WCC · Understand the traps and how to avoid them.
Assigns pressure injury stages by eyeballed depth in centimeters or by how 'deep it looks' - e.g., labels a shallow ulcer with visible subcutaneous fat as a Stage 2, or assigns a stage to a wound covered in slough/eschar instead of calling it unstageable.
Candidates memorize stage numbers and rough depth ranges but never solidify the rule that stage equals the deepest tissue layer visible, so fat, slough, and granulation get sorted by appearance rather than anatomy.
What to do instead
Drill one sentence until automatic: 'Stage by the deepest structure I can SEE, not by how deep it looks.' Then walk the ladder: intact skin with non-blanchable erythema = 1; partial-thickness dermis only, no fat = 2; fat visible = 3; muscle, tendon, cartilage, or bone = 4; obscured by slough/eschar = unstageable; intact purple/maroon or blood-filled blister = deep tissue pressure injury. If fat is visible it can never be a Stage 2.
Stages blanching erythema, incontinence-associated dermatitis, moisture-associated skin damage, or a skin tear as a pressure injury, and misses deep tissue pressure injury in patients with darkly pigmented skin.
Erythema is the most visually salient finding, and the blanching test plus palpation for temperature and induration is easy to skip at the bedside; darkly pigmented skin hides the color change candidates are trained to look for.
What to do instead
Before naming a pressure injury, apply the three-part test: correct location over a bony prominence, non-blanching under light fingertip pressure, and either intact skin or a defined tissue-loss wound. Exclude moisture, friction, tape, and shear patterns. In darkly pigmented skin, rely on temperature difference, induration, and pain rather than color alone.
Offloads heels and other bony prominences with a donut cushion, a ring, or a pillow wedged under the calf, and documents 'turn every 2 hours' as the entire offloading plan.
Donut cushions and pillows are what is physically available on the unit and were taught informally; the harm (shear and ischemia at the ring edge, pressure from the heel resting on the mattress) is not intuitive.
What to do instead
Never use ring or donut devices. Suspend the heel completely off the surface with a heel suspension boot or pillow placed lengthwise under the calf so the heel floats, and verify by sliding a hand under the heel. Write pressure-redistribution surfaces and a repositioning schedule with the specific positions and frequency into the plan, not a generic instruction.
Applies multilayer or high-compression bandaging to a leg ulcer without first establishing arterial status, or conversely withholds all compression from every patient with any vascular history.
Venous ulcers are the most common lower extremity ulcer, so the reflex is 'leg ulcer = compress'; ABI is perceived as a referral test rather than a bedside decision point.
What to do instead
Make vascular screening a gate before compression: palpable pulses, edema, skin changes, and an ABI (or toe pressure when vessels are non-compressible, as in diabetes or renal disease). Compress when arterial inflow is adequate per your protocol (commonly ABI 0.8–1.3 with supervision and reduced pressure at the lower end); do not compress an ischemic limb. Document the number you based the decision on.
Measures wounds inconsistently between visits - sometimes head-to-toe, sometimes longest-by-widest measured diagonally, no clock reference for undermining or tunneling, and tissue-type percentages that do not add to 100%.
Measurement is treated as a data-entry chore, and each clinician's ruler placement habit differs, so serial measurements reflect technique drift rather than healing.
What to do instead
Standardize one method and state it in the note: length as head-to-toe (12 to 6 o'clock) by width perpendicular (3 to 9 o'clock), depth with a moistened cotton tip, undermining and tunneling recorded by clock position and depth, and tissue types as percentages summing to 100 with a measurement method named (ruler, planimetry, photography with a scale marker). Photograph with the same camera-to-wound distance and orientation.
Treats colonization or critical colonization with systemic antibiotics, swabs the wound surface for culture, and keeps patients on topical antibiotic ointments indefinitely as 'prophylaxis'.
Purulence, odor, and heavy exudate are read as automatic infection, and a surface swab is easy; the distinction between contamination, colonization, critical colonization, and true invasive infection is fuzzy in recall.
What to do instead
Diagnose infection on host signs (increasing pain, warmth, erythema, edema, purulent drainage, fever, rising WBC/CRP, delayed healing) plus deep tissue sampling - tissue biopsy or quantitative culture from cleaned wound base, not a superficial swab. Treat critical colonization with short-course topical antiseptic (e.g., cadexomer iodine, silver) and reserve systemic antibiotics for spreading or deep infection, then stop them when signs resolve.
Selects dressings by habit or brand familiarity - gauze packed into a clean granulating wound, an occlusive hydrocolloid or film over a heavily draining or infected wound, or continuing a product because 'that's what the last nurse used'.
Product names are remembered better than the decision framework, and dressing changes are often delegated without a written rationale, so the choice is copied forward.
What to do instead
Choose by the wound's four descriptors - exudate volume, tissue type, bacterial burden, periwound condition - plus goal (debride, protect, fill dead space, manage moisture). Moist wound healing needs a moist interface and a cover matched to exudate: films and hydrocolloids for low exudate, foams and alginates/hydrofibers for moderate to heavy, no occlusive dressing over suspected infection. Write the rationale in the plan so it propagates.
Performs sharp debridement without checking perfusion, anticoagulation, or platelet status, or debrides a stable, dry, intact eschar on an ischemic heel or a heel in a patient with peripheral arterial disease.
Debridement is taught as the default first step for any non-healing wound, and the contraindication list is under-rehearsed compared with the indications.
What to do instead
Before any sharp debridement, screen for adequate perfusion, current anticoagulation or coagulopathy, immunosuppression, and wound stability. Leave stable, dry, intact eschar on an ischemic limb or a pressure area in a patient with severe PAD unless it is infected, draining, or causing pain - then obtain vascular or specialty input. Document the indication and the consent or scope of practice for each debridement.
Manages a plantar neuropathic foot ulcer with dressings and 'weight bearing as tolerated', or probes a diabetic foot wound to bone and proceeds without imaging.
The wound is the visible problem, so attention goes to topical care; offloading is treated as the patient's responsibility, and probe-to-bone is not connected to the osteomyelitis workup it triggers.
What to do instead
Offloading is the primary therapy: an irremovable total contact cast or removable cast walker made irremovable, with activity restriction, plus callus debridement and frequent re-evaluation. Treat probe-to-bone in a diabetic foot wound as osteomyelitis until imaging and bone assessment say otherwise, and refer promptly for vascular evaluation if perfusion is impaired.
Uses serum albumin or prealbumin to diagnose malnutrition and to justify a healing prognosis, and answers nutrition questions on the basis of those values alone.
Low albumin is widely quoted as 'poor nutrition', so the association is memorized without the caveat that both are acute-phase reactants suppressed by inflammation, liver disease, and renal loss.
What to do instead
Screen with a validated tool (MUST, MNA, or a nutrition screen in the history) plus weight trend, intake history, and functional status. Treat albumin and prealbumin as inflammation markers, not nutrition markers, and state that a low value reflects systemic inflammation in a patient with an open wound. Escalate to a dietitian for calorie and protein targets rather than adjusting based on a lab value.
