Learners will read skin breakdown as a downstream signal — of nutrition, perfusion, immobility, moisture, and how a person is cared for — rather than a local skin problem. Stage pressure injuries accurately, assess wounds with the TIME framework, recognize dermatologic emergencies before they kill, and treat the whole person with prevention-first, observation-first, dignity-first care.
“A pressure injury is rarely a failure of skin. It is a failure of turning, of feeding, of perfusion, of attention — the skin is simply the first place the neglect becomes visible. The western reflex treats the dressing and ignores the cause. WestNet treats the human: relieve the pressure, feed the tissue, restore the blood supply, and protect the dignity of the person whose skin you are uncovering.”

This module was developed from bedside wound-care workflow analysis across North American acute and long-term care settings — not from product brochures or dressing-company education alone. WestNet HealthOS was built because the conventional wound workflow too often treats the hole in the skin while ignoring the body that produced it.
Module 05 is not anti–wound-care. It is anti–surface-only care — the kind that orders an expensive dressing for a Stage 4 sacral wound while the patient is malnourished, dehydrated, immobile, and lying on the same pressure point for the eighth hour running.
The dressing is the smallest part of wound healing. Nutrition, perfusion, pressure relief, moisture balance, and consistent human attention do the work. A wound that will not heal is almost always a body that is not being supported to heal. Observe the whole person first; choose the dressing last.
The skin is the body’s largest organ and its most honest one. It cannot hide what is happening underneath. A breakdown over the sacrum, the heel, or the ischium is not a local accident — it is the visible endpoint of a chain: too little protein and fluid to rebuild tissue, too little blood flow to deliver it, too much pressure for too long, too much moisture macerating the surface, and too few hands turning and checking the patient.
When staff lead with the dressing, they stop seeing the body. The wound becomes a task on the cart rather than a message from the patient. That is not wound care — that is housekeeping with a sterile field.
Every wound assessment requires exposing skin that the patient may have spent a lifetime keeping private. Knock. Explain before you uncover. Drape what you are not examining. Ask permission, warm your hands, work gently, and narrate what you are doing. The same trauma-informed gentleness taught in Module 07 applies here: to a survivor of assault, being uncovered and touched without consent can re-open an old wound far deeper than the one on the skin.
Skin heals on four legs. Remove any one and the wound stalls no matter how advanced the dressing. These pillars are the lens through which every wound in this module is read.
Tissue is rebuilt from protein, calories, vitamin C, zinc, and fluid. A malnourished patient cannot close a wound — no dressing substitutes for the building blocks. Screen, feed, and involve a dietitian early (see Module 03).
Healing needs blood. Hypotension, peripheral arterial disease, anaemia, smoking, and uncontrolled diabetes starve the wound bed. Assess pulses, capillary refill, and glucose — a wound on an ischaemic limb will not heal until flow is restored.
Unrelieved pressure and shear kill tissue from the inside out; excess moisture macerates it from the outside in. Reposition, offload, manage incontinence, and keep skin clean and balanced — not too wet, not too dry.
Wounds are found, prevented, and healed by people who look. Consistent skin inspection, gentle handling, and respect for the exposed patient are clinical interventions — not courtesies. The most reliable wound prevention tool is a clinician who pays attention.
Accurate staging drives the right plan and the right resources. Staging describes the deepest tissue type visible — it is not a healing timeline, and a healing wound is never “back-staged” (a healed Stage 4 is a “healed Stage 4 pressure injury,” not a Stage 2). The NPIAP system[2] is summarised below; the interactive Stager in §13 lets you practise.
Stage 1 — intact skin, localized non-blanchable erythema. Stage 2 — partial-thickness loss, exposed dermis (shallow, pink/red, moist; or an intact/ruptured serum blister). Stage 3 — full-thickness loss into subcutaneous fat; slough may be present but bone/tendon not exposed. Stage 4 — full-thickness loss with exposed/palpable bone, tendon, or muscle. Deep Tissue Injury (DTI) — intact or non-intact skin with persistent deep red, maroon, or purple discolouration. Unstageable — full-thickness loss where the base is obscured by slough or eschar; depth cannot be determined until the bed is cleared.
Moisture-associated skin damage (incontinence dermatitis), skin tears, and arterial/venous ulcers are not pressure injuries and must not be staged as such. Stable, dry, intact eschar on an ischaemic heel is the body’s natural cover — do not debride it without confirming perfusion.
At-a-Glance — Stage Cues & Escalation. A bedside quick-reference for the six categories. Stage describes the deepest visible tissue; an obscured base cannot be numbered. Use it to orient, not to replace a hands-on assessment.
| Category | What you see | Escalate / act when |
|---|---|---|
| Stage 1 | Intact skin, localized non-blanchable erythema (often over a bony prominence) | Offload immediately and intensify SSKIN — a Stage 1 left unturned becomes an open wound |
| Stage 2 | Partial-thickness loss; shallow pink/red moist bed, or an intact/ruptured serum blister | Find and remove the pressure source; escalate if it deepens or shows infection signs |
| Stage 3 | Full-thickness loss into subcutaneous fat; slough may be present, no bone/tendon visible | Wound-care referral; reassess nutrition and perfusion; escalate if undermining or stalling |
| Stage 4 | Full-thickness loss with exposed/palpable bone, tendon, or muscle | Specialist (wound/surgical) referral now — osteomyelitis and sepsis risk are real |
| Deep Tissue Injury | Persistent deep red, maroon, or purple intact or non-intact skin — not a bruise | Offload and escalate now; it can open into a Stage 3/4 within days |
| Unstageable | Full-thickness loss whose base is hidden by slough or eschar; depth unknown | Refer for debridement (per scope/order) — but never debride stable dry eschar on an unperfused limb |
| Reading the wound | Healing — leave it to work | Infected / deteriorating — escalate |
|---|---|---|
| Tissue in the bed | Beefy-red granulation, advancing | Increasing slough or new necrosis; friable, bleeds easily |
| Exudate | Stable or decreasing, serous | Rising volume, cloudy/purulent, new odour |
| Peri-wound & edge | Pink epithelium advancing from the edge | Spreading erythema, warmth, oedema; rolled or static edge |
| Pain & the patient | Stable or easing; patient systemically well | New or rising pain; fever, tachycardia — suspect spreading infection |
Any of the following warrants prescriber/specialist review rather than another dressing change: a wound that has not shrunk in 2–4 weeks of appropriate care; new or spreading erythema, warmth, purulence, or odour; exposed bone/tendon or a probe-to-bone; rapidly advancing redness with pain out of proportion (see §08 — rule out necrotizing fasciitis); or deep purple intact skin. Verify staging definitions and management against your current local wound-care protocol and formulary — these vary by facility and jurisdiction.
Two patients with identical wounds heal at completely different rates — because healing is a whole-body capacity, not a property of the wound. The body must have the raw materials (nutrition), a delivery system (perfusion and oxygen), and an absence of ongoing injury (pressure, moisture, infection). When that capacity is low, the most advanced dressing on the market still cannot close the wound.
This reframes the central question from “What dressing should I use?” to “What is stopping this body from healing — and can I fix it?” A wound that has not improved in two to four weeks of appropriate care is almost never a dressing problem. It is a perfusion, nutrition, pressure, or undiagnosed-cause problem.
Nutrition • Perfusion & Oxygen • Pressure / Moisture Control • Mobility. Every rung of the Healing Ladder in §10 is an expression of these four. Optimise them and most wounds heal themselves.
Myth vs. Evidence. Wound care attracts more folklore than almost any field in nursing. None of the beliefs below come from bad intentions — they come from a system that rewards the visible dressing over the invisible cause. The evidence is consistent: healing is built from protein, perfusion, offloading, and glycaemic control. Treat the person, not the label — make the human whole, and the skin follows.
| Common belief | What the evidence supports |
|---|---|
| “The right dressing will heal the wound.” | A dressing protects and optimises the local bed — it does not supply the protein, blood flow, or pressure relief that actually rebuild tissue. The international pressure-injury guideline and wound-bed-preparation evidence put nutrition, perfusion, and offloading first; the dressing supports that work.[1] |
| “Nutrition is a side issue once the wound is dressed.” | Inadequate protein, energy, and fluid are among the most common reasons a wound stalls. Screening and correcting malnutrition is a core healing intervention, not an extra — involve a dietitian early (see Module 03 — Clinical Nutrition).[6] |
| “A diabetic foot wound is a dressing problem.” | It is a perfusion, pressure (offloading), and glycaemic-control problem first. Uncontrolled glucose and arterial disease blunt healing and raise infection risk; the dressing is downstream of all three (see Module 10 — Diabetes & Endocrine). |
| “Pour antiseptic in and it will clean itself out.” | Cytotoxic agents (full-strength iodine, peroxide) can harm the very cells that heal. Gentle cleansing with saline or a non-cytotoxic cleanser, plus removing non-viable tissue, is what prepares the bed. |
| “Stalled wound? Change the dressing more often.” | A wound that has not improved in 2–4 weeks of appropriate care signals an unaddressed driver — perfusion, nutrition, pressure, or an undiagnosed cause. Re-examine the body, not the product shelf. |
None of this means a colleague who reaches for a dressing is wrong — the dressing is necessary, just not sufficient. The respectful reframe is additive, not corrective: “The dressing is doing its job; let’s make sure the body can do its part too — how are we doing on protein, hydration, turning, and glucose?” That keeps the team aligned and the focus on the human, not a turf debate.
TIME is the structured way to read a wound bed at every dressing change, so that wound-bed preparation is systematic rather than habitual. Walk the four letters in order — each one points to a specific, repeatable action. None of them require an exotic product; most require only a clinician willing to look closely.
Identify what is in the bed: healthy granulation (beefy red), unhealthy slough (yellow), or necrotic eschar (black). Non-viable tissue feeds bacteria and blocks healing.
Act: Debride non-viable tissue (per scope/order) — unless it is stable dry eschar on an ischaemic limb.Look for the signs of local infection — increasing pain, erythema, warmth, oedema, odour, and rising exudate. Distinguish normal inflammation from spreading infection.
Act: Cleanse, consider topical antimicrobials for local infection; systemic signs (fever, spreading redness) demand prescriber review.The bed should be moist, not wet, not dry. Too much exudate macerates the edges; too little desiccates the bed and stalls cell migration.
Act: Match the dressing to the exudate — absorptive for heavy, hydrating for dry. Protect the peri-wound skin.The wound edge tells you whether it is healing. Advancing pink epithelium is good; rolled (epibole), undermined, or static edges signal a stalled wound.
Act: Re-assess the whole picture — a non-advancing edge means a driver (perfusion, nutrition, pressure, infection) is unaddressed.TIME is not a checklist you run past a wound. It is a conversation you have with it. The bed is telling you what the body needs — the clinician who reads it closely rarely needs the expensive dressing.
The overwhelming majority of pressure injuries are preventable. Prevention is cheaper, safer, and infinitely kinder than treatment — and it is the truest expression of attention. Run the SSKIN bundle on every at-risk patient, every shift.
Provide the right support surface — pressure-redistributing mattress or cushion matched to risk. The bed and chair are clinical equipment, not furniture.
Inspect skin head-to-toe at least each shift, especially bony prominences and under devices. Non-blanchable redness is a Stage 1 alarm — act, do not chart and move on.
Reposition on an individualised schedule; offload heels entirely. Even small, frequent shifts of weight relieve the capillary-crushing pressure that kills tissue.
Manage moisture with prompt cleansing and a barrier; treat incontinence as a skin emergency. Screen nutrition and hydration — the tissue cannot rebuild without fuel.
Oxygen tubing, masks, catheters, casts, and cervical collars cause a large and rising share of pressure injuries — in patients of every age. Check the skin under every device. Pad, rotate, and reposition tubing. A wound under a mask is no less preventable than one over the sacrum.
A new or worsening pressure injury is a sentinel event, not an inevitability. When one appears, ask what in the bundle failed: was the surface wrong, the turning skipped, the nutrition unaddressed, the device missed, the patient too unstable to reposition? Fix the system, not just the skin.
Most skin complaints are benign. A handful are emergencies that look ordinary for a few critical hours and then become catastrophic. The skill is not memorising rashes — it is knowing which features mean stop everything and escalate now.
The cardinal rule of these emergencies: pain out of proportion to what you can see, rapid progression, and systemic illness (fever, tachycardia, confusion) are far more alarming than the appearance of the skin itself.
Suspect when pain is wildly out of proportion to visible findings, the redness advances by the hour (mark and time it), the skin develops dusky/violaceous patches, blisters, crepitus, or anaesthesia, and the patient looks systemically toxic. A rising LRINEC-style picture (high CRP, WBC, low sodium) supports the suspicion[3] — but a normal score never rules it out. This needs urgent surgical and prescriber review, not a dressing. Delay costs limbs and lives.
Cellulitis is warm, tender, spreading erythema with a relatively gradual onset and proportionate pain, usually without systemic toxicity. It is treated medically. The danger is anchoring: a wound nurse who labels every red leg “cellulitis” will eventually miss the necrotizing case hiding inside one. Re-examine, mark the border, and escalate if it outpaces the antibiotics.
SJS/TEN is a life-threatening drug reaction: painful skin, a positive Nikolsky sign (skin shears with light lateral pressure), mucosal involvement (mouth, eyes, genitals), and large sheets of detaching epidermis — like a deep burn from the inside out. Suspect it after a new medication. Stop the suspected drug, escalate immediately, and treat the patient like a burns patient. This is a medical emergency, not a rash.
A patient develops rapidly spreading, exquisitely painful erythema over a single limb in the space of 12 hours. The pain is wildly out of proportion to the skin findings; the area turns dusky and violaceous with tense bullae; the patient is febrile and tachycardic, and crepitus is felt on palpation.
Resolution: Suspect necrotizing fasciitis — a surgical emergency. Do not delay for imaging. Obtain an urgent surgical consult, start broad-spectrum antibiotics, and resuscitate the patient. A LRINEC score may support the diagnosis, but it does not rule it out.
These are surgical and dermatologic emergencies — escalate now.
Wound care is one of the most intimate acts in clinical practice. It exposes the body, often in its most vulnerable places, frequently in patients who cannot move, speak for themselves, or refuse. The WestNet protocol treats every dressing change as an encounter with a person — not a procedure on a body part.
Consent: Explain before you uncover. Ask permission to look and to touch — every time, even with the non-verbal patient.
Cover: Drape everything you are not examining. Expose the smallest area for the shortest time. Warmth and privacy are clinical care.
Gentleness: Soak adherent dressings off, never rip. Pain during care is a finding, not a given — pre-medicate when needed.
Pace: Move at the patient’s tolerance, not the cart’s schedule. Narrate each step so nothing is a surprise.
Name: Use it. Speak to the person, not over them. Not “the sacral wound in 4B.”
What to Say — and What Not To. The principles above become real in the words you choose at the bedside. The phrasing below is a starting script for an exposed, anxious, or non-verbal patient and their family — adapt it to the person in front of you.
Absence of objection is not consent, and inability to speak is not absence of feeling. Watch the face, the breathing, and the body for distress; pause when you see it. The same trauma-informed gentleness taught in Module 07 protects a patient who cannot tell you that being uncovered frightens them — assume awareness, and earn trust with every touch.
A wound that is dressed is not the same as a wound that is healing. The surface-only reflex measures success by how clean the dressing looks on rounds — the wound is covered, so it is “managed.” WestNet measures whether the wound is smaller, shallower, and advancing at the edge over time. Coverage hides the problem; closure solves it. If the trend is flat, the dressing is not the answer — the body is asking for something the dressing cannot give.
The following patterns recur across North American wound-care admissions. This section presents a composite case drawn from recurring systemic failures — not any single patient, institution, or jurisdiction. The lesson is architectural, not individual.
An immobile patient develops sacral redness. It is charted but not acted on. Repositioning is documented but not consistently delivered. The patient is eating almost nothing; no nutrition referral is made. Days later the redness is a Stage 3 ulcer. The response is an escalating series of premium dressings — while the patient remains malnourished, dehydrated, and turned only sporadically. The wound deepens. The dressing budget rises. The cause is never touched.
Every safeguard in the chain fails when staff treat the surface and ignore the system. At Rung 1 of the Healing Ladder — observing the whole person — this injury should have been prevented entirely. Instead the default pathway spends heavily to cover a wound that consistent turning, a dietitian, and attention would have closed, or never allowed to open. Quiet dressings were mistaken for healing.
Staging drives the plan. Select the features you actually observe at the wound — the tool returns the most likely stage and a management bundle in real time. It mirrors the NPIAP logic: the deepest tissue type visible determines the stage, and an obscured base means you cannot stage at all. This is a teaching aid; it never replaces a hands-on assessment by a qualified clinician.
Stage describes the deepest tissue you can see. If slough or eschar obscures the base, the wound is Unstageable until cleared. Persistent deep purple/maroon discolouration of intact skin is a Deep Tissue Injury, which can deteriorate rapidly. The tool guides the call; the bedside clinician makes it.
This is one of the highest-stakes calls in wound care. Cellulitis is common and treated medically; necrotizing fasciitis is a surgical emergency that can look like cellulitis for the first few hours, then take a limb or a life. Mark what you actually observe — the tool weighs the picture and flags the critical next step.
If any hard red flag is present — pain out of proportion, rapid hourly progression, dusky skin or blisters, crepitus, anaesthesia, or systemic toxicity — treat it as necrotizing fasciitis and escalate for urgent surgical review regardless of the meter. A normal LRINEC-style picture never rules it out. This tool supports — never replaces — prescriber and surgical assessment.
The words in the chart shape the care that follows. Vague, judgemental, or surface-only notes hide the cause and stall the wound. Objective, observation-first language drives the right action — and protects the patient’s dignity. Tap any card to flip the weak note into one that works, and see why it lands differently.
A chart that says “dressing changed, tolerated well” tells the next clinician nothing and lets a deteriorating wound hide in plain sight. A chart that records tissue type, size, exudate, edge, pain, and the drivers being addressed turns the note into a clinical tool — and keeps the focus on the human, not the hole.
“Chronic wound” is not a diagnosis — it is a description. Before a single dressing is chosen, the clinician must answer the question the wound is really asking: what caused you, and what is keeping you open? A venous ulcer treated as arterial, or a pyoderma treated as pressure, will never close. The five great families below cover the overwhelming majority of wounds you will meet, and each one points to a different cause that must be fixed first.
| Wound family | Typical location | Classic appearance | Cause to fix first |
|---|---|---|---|
| Pressure injury | Bony prominences — sacrum, heels, ischium, occiput, under devices | Over a bone; staged by depth; non-blanchable erythema to exposed bone | Unrelieved pressure / shear — offload (see §04, §07) |
| Venous leg ulcer | “Gaiter” area — medial lower leg above the ankle | Shallow, irregular, wet; haemosiderin staining, oedema, varicosities | Venous hypertension — compression (only if arterial flow adequate) |
| Arterial / ischaemic ulcer | Toes, foot, lateral malleolus, pressure points | “Punched-out,” dry, pale/necrotic base; cold limb, absent pulses, severe pain | Inadequate perfusion — restore blood flow; do NOT compress |
| Diabetic foot ulcer | Plantar surface, under metatarsal heads, toe tips | Round, callused rim, often painless (neuropathy); may probe deep | Pressure (offloading) + glucose + perfusion (see §18) |
| Skin tear | Forearms, hands, lower legs of fragile/elderly skin | Traumatic flap; epidermis separated from dermis; a known cause | Trauma + skin fragility — preserve the flap, protect the skin (see §19) |
Two wounds can look identical and need opposite treatment. The lethal example: a venous ulcer is treated with compression and heals; an arterial ulcer treated with compression loses the limb. Always assess perfusion before you commit to a plan. The appearance tells you what it looks like; the cause tells you what to do.
If a wound does not fit a common family, heals abnormally, has rolled/violaceous “heaped” or undermined purple borders, or fails appropriate care, think beyond the usual: pyoderma gangrenosum (do not debride — it worsens), vasculitis, malignancy (a Marjolin ulcer in a chronic wound), or calciphylaxis. These need diagnosis, not another dressing — refer.
Pick the features you actually observe. The tool leans toward the most consistent wound family and names the cause to address first. A teaching aid — it never replaces vascular assessment or clinician judgment.
Naming the family is not academic — it changes the whole plan, the dressing, and whether compression is safe or catastrophic. A wound mislabelled is a cause untreated, and a cause untreated is a wound that will not close no matter how good the dressing.
The lower leg is where the most dangerous wound-care mistake in nursing happens: applying compression to a limb that cannot tolerate it. Venous and arterial ulcers can look superficially similar, yet their treatments are opposites. The whole-person discipline of this module — assess the cause before the dressing — is nowhere more literally life-and-limb than here.
Medial “gaiter” area above the ankle. Shallow, irregular border, wet/exudative bed. Surrounding skin shows haemosiderin (brown) staining, oedema, varicose veins, and lipodermatosclerosis. Pulses usually present; pain relieved by elevation. Cause: blood pools and pressure rises in the venous system.
Toes, foot, lateral malleolus, pressure points. “Punched-out,” well-defined, dry, pale or necrotic base, minimal exudate. Limb is cold, hairless, shiny; pulses weak/absent; pain is severe and worse with elevation, better hanging down. Cause: the artery cannot deliver blood.
Compression is the cornerstone of venous-ulcer healing — and a limb-threatening error on an ischaemic leg. An ankle–brachial pressure index (ABPI) is checked before compression: a normal range supports full compression; a low value contraindicates it; a high value can be falsely elevated (calcified vessels in diabetes) and needs specialist interpretation. If you cannot confirm arterial flow is adequate, do not apply compression — refer. Verify ABPI thresholds and the compression formulary against your current local vascular protocol.
Many older patients have both venous and arterial disease. These “mixed” ulcers require specialist assessment to determine whether (and how much) reduced compression is safe. Never assume; never guess. When the picture is mixed or unclear, the safe default is no compression until a vascular clinician has weighed in.
| Feature | Venous | Arterial |
|---|---|---|
| Site | Medial gaiter area | Toes, foot, lateral malleolus |
| Edge / base | Irregular, shallow, moist | Punched-out, deep, dry/necrotic |
| Exudate | Moderate–heavy | Minimal |
| Pulses | Usually present | Weak or absent |
| Pain | Better with elevation | Worse with elevation; eased hanging down |
| Surrounding skin | Haemosiderin staining, oedema, varicosities | Cold, pale, shiny, hairless |
| Compression | Cornerstone (if ABPI adequate) | Contraindicated — restore flow first |
The diabetic foot ulcer is the clearest case in this module of a wound that is never a dressing problem. Three forces converge: neuropathy (the patient cannot feel the injury), ischaemia (perfusion is impaired), and unrelieved pressure (the patient keeps walking on it). Add elevated glucose blunting immunity and healing, and a small ulcer becomes an amputation. The dressing is the least of it; offloading, perfusion, and glycaemic control do the work (see Module 10 — Diabetes & Endocrine).
Loss of protective sensation means the patient feels no warning pain. They walk on a wound, a stone in the shoe, or an ill-fitting boot for days. Inspect the feet every visit — including between the toes and the sole — because the patient cannot.
Peripheral arterial disease starves the wound. Assess pulses and perfusion; a non-healing diabetic foot ulcer with poor flow needs urgent vascular review. Perfusion is a prerequisite for any plan — not an afterthought.
Healing is impossible while the patient walks on the ulcer. Offloading — total-contact cast, removable walker, or specialist footwear — is the single most important intervention. A dressing under a weight-bearing foot is a dressing being crushed.
High glucose impairs white cells and healing; the diabetic foot infects fast and quietly. “Probe to bone” raises osteomyelitis suspicion. Control glucose with the team and treat infection early and seriously.
If a sterile probe in the ulcer reaches bone, suspect osteomyelitis until proven otherwise — escalate for imaging and specialist review. A diabetic foot ulcer with spreading redness, swelling, odour, or systemic signs is a limb emergency, not a routine dressing change. The classic trap is the “painless” foot that looks calm while infection tracks deep — neuropathy hides the alarm.
Diabetic foot ulcers are commonly graded (e.g., the Wagner system, 0–5, by depth and the presence of infection or gangrene) to standardise communication and trigger the right referral. The strongest evidence in this field is for the team: podiatry, vascular, endocrine, wound care, and nursing acting together prevent amputations. The lone dressing change does not. Verify grading and referral pathways against your current local diabetic-foot protocol.
A skin tear is a traumatic wound caused by shear, friction, or blunt force that separates the epidermis from the dermis (a partial-thickness tear) or both layers from underlying tissue (a full-thickness tear). They are overwhelmingly a problem of fragile skin — the very old, the very young, the steroid-dependent, the dehydrated — and they are largely preventable. They are not pressure injuries and must not be staged as such.
The International Skin Tear Advisory Panel groups skin tears by how much of the skin flap remains and can be re-approximated: Type 1 — no skin loss; the flap can be realigned to cover the wound. Type 2 — partial flap loss; the flap cannot fully cover the bed. Type 3 — total flap loss; the wound bed is fully exposed. Classifying guides the dressing and the prognosis; the goal in every type is to preserve viable tissue.
If a viable flap is present, the single most valuable action is to gently re-approximate it over the wound bed — it is the patient’s own best dressing. Irrigate, ease the flap back into place (a moistened cotton tip helps), and secure with a non-adherent, low-trauma dressing. Mark the dressing with an arrow showing the direction of removal so the next clinician peels toward the flap’s attached base, never lifting it off again.
Standard adhesive tape on fragile skin causes the next tear when it is removed — a self-inflicted, iatrogenic wound. Use silicone or non-adherent contact layers and tubular/roll retention rather than tape directly on the skin. Removing a dressing should never create a new wound.
Prevention is the real treatment. Fragile-skin patients live one careless transfer away from the next tear. The prevention bundle is simple, cheap, and dignified — and it reflects the same attention-first philosophy as the SSKIN bundle in §07.
Twice-daily emollient on fragile limbs measurably reduces skin-tear incidence. Hydrated skin tears less. This is one of the highest-yield, lowest-cost interventions in the whole module.
Long sleeves, shin guards, padded bed rails and wheelchair leg-rests, and clearing sharp edges from the environment prevent the blunt knocks that tear thin skin.
Use proper transfer technique and slide sheets; never drag a limb or grip fragile forearms. Shear during a transfer is the classic mechanism — lift, don’t drag.
Systemic hydration and adequate protein make skin more resilient. The same nutrition that closes wounds also helps skin resist tearing in the first place.
Most surgical wounds heal predictably by primary intention — clean edges held together by sutures, staples, glue, or strips, sealing within hours and epithelialising over days. The clinician’s job is to protect that closure, recognise when it is failing, and know the difference between normal healing and surgical-site infection (SSI) or dehiscence.
| Healing pathway | What it means | Typical example |
|---|---|---|
| Primary intention | Edges approximated and closed; minimal tissue loss | Sutured surgical incision, clean laceration |
| Secondary intention | Left open to granulate and contract from the base up | Pressure injury, abscess cavity, dehisced wound |
| Tertiary (delayed primary) | Left open initially (e.g., for contamination), then closed later | Contaminated abdominal wound closed after a few days |
Dehiscence is partial or complete separation of a closed surgical wound — often heralded by a sudden gush of serosanguineous fluid and a “giving way” sensation reported by the patient. Evisceration — protrusion of viscera (e.g., bowel) through the wound — is a surgical emergency: cover the exposed organs with saline-moistened sterile gauze, keep the patient still and flat with knees flexed, keep them NPO, and call surgery now. Do not attempt to push anything back in.
Suspect SSI with increasing pain after the early post-op days, spreading erythema beyond the immediate incision, warmth, swelling, purulent drainage, wound breakdown, or new fever. The honest reading is timing: a little redness on day one is expected; increasing redness, pain, and drainage on day four is a warning. Escalate for prescriber review rather than simply re-dressing.
Keep the incision clean and dry for the initial sealing window per surgical orders; handle with clean/aseptic technique; do not disturb strips or glue prematurely; and teach the patient to support the wound (a pillow splint) when coughing or moving. Closure is fragile until the tissue catches up — the dressing buys time for biology, it does not replace it.
Excess moisture destroys skin from the outside in — and it is constantly mistaken for a pressure injury, then mistreated. Moisture-associated skin damage (MASD) is inflammation and erosion of the skin from prolonged exposure to urine, stool, sweat, wound exudate, or fistula output. Distinguishing it from a Stage 2 pressure injury is one of the most common — and consequential — bedside calls in this module.
| Feature | Moisture damage (MASD) | Pressure injury (Stage 2) |
|---|---|---|
| Location | Skin folds, peri-anal, peri-wound — wherever moisture sits | Over a bony prominence |
| Shape / edges | Diffuse, irregular, “blotchy,” ill-defined | More distinct; conforms to the bony point |
| Depth | Superficial erosion; rarely full-thickness alone | Partial-thickness loss with a defined bed |
| Cause | Moisture ± friction | Pressure / shear over a bone |
| First fix | Remove the moisture; barrier protect | Offload the pressure |
IAD (incontinence-associated dermatitis) — from urine/stool. ITD (intertriginous dermatitis) — trapped moisture and friction in skin folds. Peri-wound maceration — from excess exudate. Peristomal/peri-fistula MASD — from effluent. The cause differs but the principle is identical: the skin is wet for too long.
Cleanse gently with a pH-balanced no-rinse cleanser — not harsh soap and a rough cloth. Protect with a barrier (cream, film, or paste) so the skin is shielded before the next episode. Contain the source — a continence plan, appropriate absorbent products, exudate-matched wound dressings, a well-fitted stoma appliance. Treating MASD with a “cream” while leaving the skin soaking is treating the surface and ignoring the cause — the same error this whole module is built to correct.
Macerated, eroded skin is the perfect launch pad for a pressure injury and for infection — the two often co-exist. Moisture and pressure compound each other. Treat incontinence as a skin emergency, not a laundry problem: every hour of contact is more damage. Verify product choices against your facility skin-care formulary.
The dressing is the smallest part of healing — but choosing it well still matters, because the wrong dressing actively stalls a wound (a dry dressing on a dry bed desiccates it; an absorbent one on a dry bed sticks and traps). The discipline is simple: match the dressing to the wound bed and the exudate, protect the peri-wound skin, and step down as the wound improves. Below is a working knowledge of the major families. None of this overrides your facility formulary.
| Dressing family | Best for | Watch out for |
|---|---|---|
| Hydrocolloid | Light exudate; shallow Stage 2; promotes autolysis | Not for heavy exudate or infected wounds; can macerate edges |
| Hydrogel | Dry or sloughy beds; donates moisture; aids autolytic debridement | Will macerate a wet wound — wrong for heavy exudate |
| Foam | Moderate–heavy exudate; cushioning; many anatomical shapes | Too absorbent for a dry bed — can dry it out |
| Alginate | Heavy exudate; bleeding/packing cavities (very absorbent, gels) | Needs moisture to work — dries out and sticks on a dry wound |
| Hydrofiber | Heavy exudate; locks fluid vertically, protecting edges | Same caution as alginate on dry beds |
| Transparent film | Superficial wounds, securing other dressings, protecting at-risk skin | Non-absorbent — never on a moderately/heavily exuding wound |
| Antimicrobial (e.g., silver, iodine, PHMB) | Locally infected or high-bioburden wounds, short courses | Not routine; reassess and step down — not for clean granulating beds |
| Non-adherent contact layer | Fragile beds, skin tears, low-trauma cover under a secondary dressing | Needs a secondary dressing to manage exudate |
Everything above reduces to one idea from the “M” of TIME (§06): a dry bed needs moisture donated; a wet bed needs moisture absorbed; a balanced bed needs to be protected and left alone. Get the moisture wrong and even the most expensive product fails. Get it right and a simple dressing usually suffices.
Describe the bed in front of you. The selector suggests a dressing category and explains the reasoning — it is a teaching aid, not a product endorsement, and never overrides your facility formulary or a prescriber order.
Dressing names and indications vary by manufacturer and by facility formulary, and infected wounds, ischaemic limbs, and atypical wounds change the rules. Verify every choice against your current local wound-care formulary and the prescriber’s plan. When a wound is not progressing, change the assessment — not just the product.
Debridement is the removal of non-viable tissue — slough and necrotic eschar — that feeds bacteria, harbours biofilm, and physically blocks healing (the “T” of TIME, §06). It is one of the most powerful wound interventions and one of the most consequential to get wrong. The first decision is never how to debride; it is whether to debride at all.
Do not debride stable, dry, intact eschar on an ischaemic or unperfused limb — that dry cover is the body’s natural protection, and removing it on a limb that cannot heal exposes a wound that will not close and may invite infection or amputation. Confirm perfusion first. Debridement is also contraindicated or specialist-only in pyoderma gangrenosum, in actively bleeding or anticoagulated patients (for sharp methods), and wherever it exceeds your scope of practice.
| Method | How it works | Speed | Notes |
|---|---|---|---|
| Autolytic | The body’s own enzymes liquefy non-viable tissue under a moisture-retentive dressing | Slow | Gentle, selective, low pain; widely within nursing scope; needs a perfused wound |
| Enzymatic | A topical enzyme preparation digests non-viable tissue | Moderate | Selective; requires an order; follow product directions exactly |
| Mechanical | Physical removal — monofilament pads, irrigation, (historically) wet-to-dry | Moderate | Wet-to-dry gauze is non-selective and painful — largely outdated; prefer monofilament/irrigation |
| Sharp / surgical | Scalpel, scissors, or curette remove non-viable tissue | Fast | Most rapid; requires advanced competency/credentialing and often a prescriber; check scope |
| Biological (larval) | Sterile medical maggots selectively digest slough | Fast (selective) | Highly selective; specialist-initiated; useful when surgery is unsuitable |
Describe the situation. The matcher suggests a reasonable method and flags when not to debride at all. A teaching aid only — method choice depends on scope, credentialing, perfusion, and a prescriber order.
Sharp/surgical debridement is an advanced skill restricted by jurisdiction and facility credentialing. Never exceed your scope; when in doubt, refer to a wound specialist. Always confirm perfusion before removing eschar, and verify against your current local protocol.
Every open wound carries bacteria — contamination is universal and not, by itself, infection. The clinically useful idea is a continuum: bacteria move from harmless presence to active tissue invasion along a spectrum, and the clinician’s task is to recognise where a wound sits and act proportionately. Over-treating contamination wastes antimicrobials and breeds resistance; under-treating invasion costs tissue.
Classic infection signs (heat, redness, swelling, pus) are overt. But chronic wounds often show covert signs first: a wound that simply stops progressing, bright-red friable granulation that bleeds easily, increasing or new odour, new wound pain, and pocketing or bridging at the base. A non-healing wound with no obvious pus may still be locally infected — read the subtle signs, not just the dramatic ones.
Biofilm is a community of bacteria that builds a protective self-made matrix, anchoring to the wound bed and shrugging off antibiotics and the immune system. It is invisible to the eye, reforms within hours of disruption, and is a leading reason chronic wounds stall despite “good” dressings. You cannot dressing your way through biofilm.
The evidence-aligned response to biofilm is mechanical and repeated: cleanse the whole wound and peri-wound at every change, debride non-viable tissue to physically break up biofilm (see §23), refashion the edge, and dress — using a topical antimicrobial for a defined period when local infection is suspected, then stepping down. Because biofilm reforms fast, consistency beats potency. This is wound hygiene, not a one-time clean. Antibiotic and antiseptic choices must follow your local antimicrobial-stewardship and wound-care protocols.
Negative pressure wound therapy — “wound VAC” in common speech — applies controlled sub-atmospheric pressure to a sealed wound through a foam or gauze filler and an occlusive drape connected to a pump and canister. Used for the right wound, it is a powerful adjunct. Used for the wrong wound, it causes serious harm. It is an adjunct, never a substitute for treating the cause.
Continuously draws away excess fluid and infectious material, reducing oedema and keeping the bed balanced — especially useful in heavily exuding wounds.
Mechanical micro-deformation of the bed stimulates perfusion and granulation tissue, and the suction draws the wound edges inward (macrostrain), helping contraction.
Helps prepare large, deep, or dehisced wounds for delayed closure, flaps, or grafts — and protects certain closed surgical incisions at high risk of breakdown.
A sealed system can stay in place for days, reducing disturbance of the bed and the burden of frequent changes — when the seal and the wound allow.
NPWT is contraindicated or hazardous with: untreated osteomyelitis or untreated wound infection; necrotic tissue with eschar still present (debride first); malignancy in the wound; exposed blood vessels, anastomoses, organs, or nerves (risk of catastrophic bleeding — a recognised cause of death); and unexplored fistulae. Bleeding is the most dangerous complication. If a patient on NPWT has frank blood in the canister or tubing, stop and escalate immediately. Application and settings are a prescriber/specialist decision per local protocol.
Watch the seal (loss of vacuum stalls therapy and can macerate skin), the canister (volume and colour — frank blood is an emergency), the peri-wound skin under the drape, the foam count (every piece placed must be removed — document the count), and the patient’s pain and systemic signs. NPWT does not excuse neglecting nutrition, perfusion, and offloading — those still do the healing.
Burns are a wound where the first minutes shape the outcome. Two questions drive everything: how deep is the burn (which governs healing and grafting) and how large is it as a percentage of total body surface area (TBSA, which governs fluids and transfer). The skin’s lost barrier means fluid loss, hypothermia, and infection are immediate threats — a large burn is a whole-body emergency, not a skin problem.
| Depth | Layers involved | Appearance | Pain & healing |
|---|---|---|---|
| Superficial (1st degree) | Epidermis only | Red, dry, no blisters; blanches | Painful; heals in days, no scar (e.g., sunburn) |
| Superficial partial-thickness | Epidermis + upper dermis | Moist, pink/red, blisters; blanches | Very painful; heals in ~2–3 weeks, usually no graft |
| Deep partial-thickness | Epidermis + deeper dermis | Wet/waxy, red-and-white, sluggish or no blanch | Variable pain; slow; may need grafting |
| Full-thickness (3rd degree) | Entire dermis ± below | Leathery, white/charred/brown, dry; no blanch | Painless in the centre (nerves destroyed); needs grafting |
For a rapid adult TBSA estimate, the body is divided into regions of roughly 9% (or multiples): head & neck 9%, each arm 9%, the front of the torso 18%, the back of the torso 18%, each leg 18%, and the perineum 1%. The patient’s own palm (with fingers, “palmar surface”) approximates ~1% and is handy for small or scattered burns. Children differ (proportionally larger heads) — use a paediatric chart. Estimate only partial- and full-thickness areas; superficial (red, non-blistered) burns are not counted in TBSA for fluid decisions.
Stop the burning (cool running water for a sustained period, never ice), remove non-adherent hot clothing and jewellery, cover with a clean non-adherent layer, keep the patient warm, and manage pain. Escalate / consider burn-centre referral for: large TBSA; any full-thickness burn; burns to the face, hands, feet, genitals, or over joints; circumferential burns; electrical, chemical, or inhalation injury; and burns in the very young, very old, or medically frail. Airway first if there is any inhalation concern. Verify fluid formulas and referral thresholds against your current local protocol — this module does not specify volumes.
Most rashes are not emergencies (those live in §08), but the bedside clinician is often the first to see them and the first asked “what is this?” A working vocabulary helps you describe a lesion accurately, recognise the common benign patterns, and — most importantly — know when something ordinary-looking deserves a closer look. The discipline is the same as the rest of this module: describe what you see objectively before you label it.
Macule — flat, <1cm colour change. Patch — flat, >1cm. Papule — raised, <1cm. Plaque — raised, flat-topped, >1cm. Vesicle — small fluid blister. Bulla — large fluid blister. Pustule — pus-filled. Wheal — transient raised oedematous (hives). Nodule — deeper, solid. Note distribution, colour, whether it blanches, and whether mucosa is involved — a clear description travels better than a guessed diagnosis.
A bedside atlas. Tap each card to turn the everyday presentation into the key recognition feature and the practical action. These are common, generally non-emergent patterns — but each card notes the line at which it stops being routine.
One rash rule overrides everything in this section: a non-blanching rash (petechiae/purpura that stays visible when pressed — the “glass test”) in an unwell, especially febrile, patient may signal meningococcal sepsis or another life-threat. That is not a dermatosis — it is an emergency. Escalate immediately. When in doubt about any rash, describe it precisely and ask for review rather than guessing.
Clinicians who undress patients for wound and skin care are in the single best position in the health system to catch a skin cancer early — often on skin the patient cannot see (the back, the scalp, the soles). You are not expected to diagnose; you are expected to notice and refer. The most dangerous common skin cancer, melanoma, is highly curable when caught early and lethal when missed. A few seconds of attention during routine care saves lives.
Basal cell carcinoma (BCC) — the most common; a pearly, translucent papule with fine surface vessels, often on sun-exposed skin; may ulcerate (“rodent ulcer”) and rarely spreads but grows locally. Squamous cell carcinoma (SCC) — a scaly, crusted, or ulcerated firm lesion on sun-damaged skin; can metastasise. Melanoma — the deadliest; arises in a new or changing pigmented lesion. Any non-healing “wound” that will not close, especially on sun-exposed skin, may be a skin cancer — a Marjolin ulcer can also arise in a chronic wound or scar. Refer rather than re-dress.
The ABCDE rule for pigmented lesions. A practical screen for which moles deserve a closer professional look. Tick the features you observe on a pigmented lesion — the tool tallies the warning signs and frames the next step. It does not diagnose; concerning lesions need a clinician’s assessment.
Evolution — any change over time — is the strongest single warning sign, even when A–D look reassuring. A lesion that is new, growing, changing colour or shape, itching, bleeding, or simply “different from the others” (the ugly-duckling sign) warrants referral. Also escalate any pigmented lesion that bleeds or ulcerates without trauma. When in doubt, photograph (with consent) and refer — never shave, freeze, or “treat” a suspicious pigmented lesion yourself.
Of the four pillars (§03), nutrition is the one most often acknowledged and least often acted on. A wound is a construction site, and construction needs materials: a malnourished body literally cannot manufacture the collagen, immune cells, and new tissue that close a wound. Screening and correcting nutrition is not an adjunct to wound care — it is wound care, and it belongs in the plan from day one (see Module 03 — Clinical Nutrition).[6]
| Building block | Role in healing | Practical note |
|---|---|---|
| Protein | The raw material for collagen, granulation, and immune cells; demand rises with a wound | The most important macronutrient for healing; deficiency stalls wounds. Involve a dietitian for targets. |
| Energy (calories) | Fuels the whole repair process; without it, the body burns protein for energy instead of building tissue | Adequate non-protein calories “spare” protein for healing. |
| Fluid / hydration | Maintains perfusion to the wound bed and skin turgor | Often the simplest deficit to miss and to fix; dehydration impairs delivery. |
| Vitamin C | Essential cofactor for collagen cross-linking and capillary integrity | Deficiency impairs collagen; correct a documented deficiency — do not megadose blindly. |
| Zinc | Cofactor in protein synthesis, cell proliferation, and immune function | Supplement a documented deficiency only; excess impairs healing and copper status. |
| Vitamin A, iron, copper | Support epithelialisation, oxygen delivery, and collagen | Address as part of overall status; iron supports the perfusion/oxygen pillar. |
This module specifies no doses. Routinely flooding patients with high-dose vitamin C or zinc “to heal a wound” is not evidence-based, can cause harm (zinc excess impairs copper and immune function), and substitutes a supplement for the real work of feeding the patient. Correct documented deficiencies, optimise overall protein and energy, and let a dietitian set targets. Verify any supplementation against your current local protocol and the dietitian’s plan.
Reach for real food and fluid before reaching for the supplement shelf. Screen every at-risk and wounded patient for malnutrition (a validated tool, per facility policy), make eating possible and dignified (positioning, assistance, dentures, preferences, time), fortify meals, and bring in a dietitian early. The body that is fed heals the wound; the most expensive dressing on a starving patient still fails. Make the human whole, and the skin follows.
When a colleague is reaching for another premium dressing on a stalled wound, the additive, non-corrective question is simple and diplomatic: “The dressing’s fine — are we sure this patient is actually eating and drinking enough to build new tissue? Should we get a nutrition screen and the dietitian in?” It keeps the team aligned and moves the focus to the cause.
Pressure is the cause; offloading is the cure. No dressing, nutrient, or antimicrobial can heal tissue that is being crushed against bone hour after hour. This section turns the “Keep moving” and “Surface” elements of SSKIN (§07) into concrete bedside practice — the mechanical work that prevents most pressure injuries and is non-negotiable for healing the ones that occur.
Capillaries are crushed when external pressure exceeds the pressure inside them, cutting off oxygen and nutrients to the tissue between skin and bone. Shear (skin dragged one way while deeper tissue stays) and friction compound the damage. The danger is a product of pressure × time: high pressure for a short time, or modest pressure for a long time, both kill tissue. Relieving the load — even briefly, even often — is what lets blood back in.
Turn and reposition at-risk patients on an individualised schedule, and encourage small frequent weight shifts in chairs. The schedule is documented and delivered, not just charted — a turn written but not done heals nothing.
The heel has almost no padding over bone. Float it off the surface entirely with a pillow under the calf (not under the heel), or a heel-offloading device. Heels are second only to the sacrum for pressure injuries.
A 30-degree side-lying tilt (and limiting head-of-bed elevation, which drives sacral shear) keeps weight off the bony trochanter and sacrum better than lying directly on the hip. Position with pillows to hold the angle.
Choose the support surface for the patient’s risk — from a pressure-redistributing foam mattress to powered alternating-pressure or low-air-loss systems for high risk. The bed and cushion are clinical equipment; reassess as risk changes.
The most advanced mattress does not replace repositioning — it buys margin, it does not abolish the need to move the patient. Equally, seated patients are at high risk: time in a chair concentrates pressure on the ischium and needs its own offloading and weight-shift plan. Reassess offloading whenever the patient’s mobility, weight, or medical stability changes. Verify repositioning frequency and surface selection against your current local protocol.
Every theme of this module converges here: the most reliable pressure-injury prevention “device” is a clinician who returns, looks, and moves the patient — gently, with consent, on the patient’s schedule. Offloading is the four pillars and the “Be Human” protocol (§09) expressed as hands on a patient at the bedside.
Eight applied, single-best-answer scenarios that draw the deep-dive sections together. Pick an answer to see whether it is correct and why — the reasoning matters more than the score. This is formative self-check practice; it is separate from the graded Competency Assessment in §33.
If an answer surprises you, return to the section it draws from and re-read the reasoning. Every scenario here reflects a real decision point from this module — perfusion before compression, offloading before dressings, cause before cover. Verify all clinical decisions against your current local protocols.
The clinical guidance in this module is drawn from peer-reviewed literature indexed by the U.S. National Library of Medicine (PubMed / PMC) and from current clinical-practice guidelines published by major wound-care and infectious-disease bodies. Each citation below links to its source — journal articles to a PubMed title search, guideline bodies to their official publication.
Staging definitions follow NPIAP/EPUAP; prevention reflects the international pressure-injury guideline; the cellulitis-vs-necrotizing-fasciitis logic draws on the IDSA skin-and-soft-tissue guideline and the LRINEC literature. These sources inform — but never replace — facility policy, physician orders, and jurisdictional scope of practice.
