17.1 Teaching Skin and Wound Principles, Procedures, and Goals

Quick Answer: A CWCN in-service starts with the goal of the plan—healable, maintenance, or palliative—then teaches staging versus moisture-associated skin damage (MASD), a measurement method two nurses can repeat, dressing-change technique, and the photo rules the unit will actually follow. Do not reverse-stage a healing pressure injury. Stop standing “wet to dry daily” language when the wound is not a debridement project.

This OpenExamPrep section is independent teaching for nurses studying how a Certified Wound Care Nurse (CWCN) educates other clinicians. It is not a WOCNCB publication and does not speak for the board.

Why most unit in-services fail by morning shift

Staff do not fail because they have never heard the word “stage.” They fail because the 15-minute huddle taught labels without teaching what the night nurse is supposed to do at 02:00. A slide deck that recites Stage 1 through Stage 4, then ends with “call the wound nurse if you have questions,” produces three predictable errors the next night: a new graduate stages incontinence-associated dermatitis as a Stage 2 pressure injury; a physician’s standing order for wet-to-dry gauze continues on a maintenance wound that should stay moist and undisturbed; and a CNA documents “turned q2h” while the patient remains on the same sacral surface.

Your job in Education and Referral content is not to make every colleague a wound specialist. It is to give each role a small, testable skill set and a clear trigger to call the CWCN. If the in-service cannot be demonstrated at the bedside, it will not change the night-shift note.

A 12-minute agenda that survives a busy unit looks like this: two minutes reading the goal line from a real chart; three minutes comparing MASD with a pressure injury using two bedside descriptions (or approved teaching photos); two minutes measuring one wound together; three minutes walking a dirty-to-clean dressing sequence; two minutes rewriting one wet-to-dry order and posting the call-the-CWCN list. That sequence is the teaching product. The slide deck is optional.

Teach the goal before you teach the dressing

Wound-bed-preparation language—healable, maintenance, and nonhealable/palliative—is the first sentence of every in-service, because the same sacral wound can correctly receive three different plans. Night shift will default to the last dressing they were praised for. If that dressing was wet-to-dry on a debridement week last month, they will wet-to-dry a comfort-goal wound tonight unless you teach the goal as an order they can see.

If the electronic record still says “wet to dry daily,” night shift will execute that sentence even after your lecture. The teaching intervention is order language, not another poster. Offer a replacement the provider can sign now: “cleanse with saline, apply [named dressing], change every [interval] or when strikethrough, goal = maintenance / odor control.” Stand there while the order is edited, or escalate if it is not. A hallway script that works with physicians who still write wet-to-dry: “The order reads wet-to-dry. The documented goal is maintenance. Wet-to-dry is nonselective mechanical debridement and will not serve this goal. I recommend [named dressing and interval]. Can we change the order on this screen?”

Wet-to-dry has a narrow historical use as mechanical debridement of slough on a healable wound when a more selective method is not available. It is painful, cools the bed, and removes granulation with the gauze. It is the wrong default for a granulating healable wound, a maintenance wound waiting on perfusion or sitting-time changes, or a palliative wound whose job is comfort. Teaching “we never use gauze” is weaker than teaching “gauze frequency must match this patient’s goal.”

Scenario. A 78-year-old with advanced dementia has a 3 cm sacral wound with slough, no palpable foot pulses, and a documented palliative goal. At 03:10 a night nurse soaks coarse gauze, packs tightly, and plans to rip it out at 07:00 because “that is how we debride.” The CWCN teaching point is not that wet-to-dry is forbidden in every setting. The point is that this wound’s goal is comfort and containment. Nonselective mechanical debridement adds pain, cooling, and trauma without a realistic closure path. Teach the night nurse the goal line in the plan, the dressing that matches it, and when to page you: spreading erythema, fever, a sudden odor change, or a dressing that cannot contain exudate.

Staging versus MASD: the new-graduate module

Pressure-injury staging names the deepest tissue you can see or palpate after you have decided the injury is from pressure and/or shear, usually over a bony prominence or under a device. MASD is inflammation from too much moisture—urine, stool, sweat, effluent, or wound exudate—often plus friction. Isolated MASD is not given a pressure-injury stage number. Incontinence-associated dermatitis is the MASD subtype new graduates meet first. Intertriginous dermatitis under a pannus and periwound maceration are the next two.

Teach a side-by-side, not a monologue:

• Location: pressure over sacrum, heel, trochanter, ischium, occiput, or under a device; MASD in the natal cleft, perineum, under a pannus, under a leaking pouch, or in a skin fold.
• Shape: pressure often has a more distinct edge; MASD is irregular and “water-color,” and may show kissing or satellite lesions if yeast is present.
• Color and blanching: Stage 1 is intact skin with nonblanchable erythema, or a persistent color change that does not blanch in darker skin. Many MASD areas remain blanchable and sting.
• Depth and necrosis: isolated MASD is typically partial thickness and does not produce dry eschar. Full-thickness loss, slough, or eschar over a bony prominence is not “just moisture.”
• Combined injury: a moist, sheared sacrum can be both. Teach staff to describe what they see and call the CWCN rather than force a single label at 02:00.

CNAs do not stage. Teach them to report new redness that does not fade after pressure is removed, a new open area, a device mark, wet linen, or a patient who says the skin burns. That report is a successful in-service. Correcting a CNA for “not knowing Stage 2” trains silence. New graduates get a different standard: they may draft a stage when the anatomy is classic, but they call before they enter a number when the border is irregular, the site is perineal, or satellite papules are present.

Do not reverse-stage, and do not let the record do it for you

Lost dermis, subcutaneous fat, and muscle are not rebuilt as the original tissue. A healing Stage 4 remains a healing Stage 4, and a closed injury remains a closed Stage 4 (or the facility’s equivalent closed-full-thickness language). Measurements, tissue percentages, exudate, and a tool such as PUSH document progress. If a physician or coder writes “now Stage 2” because the wound is smaller and pink, the in-service correction is: do not reverse-stage; keep the original stage and describe the current bed. Show one before-and-after note pair so staff can copy the pattern. If the EHR drop-down invites reverse-staging, teach a workaround the health-records team will accept, then fix the drop-down.

How to measure so the next shift can repeat it

Pick the facility method and drill it until two nurses get the same numbers. Consistency beats a debate about which published method is slightly better.

1. Position the patient the same way each time.
2. Length along the head-to-toe axis; width left-to-right, perpendicular to length; depth with a moist cotton-tipped applicator at the deepest point, then measured against a ruler—not guessed from a photo.
3. Undermining and tunneling by the clock, with 12:00 toward the patient’s head.
4. Record centimeters, percent tissue types, and exudate amount and character after cleansing.
5. If you cannot see the base, say so. Do not invent a stage or a depth through eschar.

Teach when to measure: on the scheduled assessment day, not at every linen change. Extra measurements that do not change the plan still cool the bed and hurt the patient.

Dressing-change technique and photo policy you can watch

A teachable sequence beats a product catalog:

1. Premedicate when the wound is painful; wait long enough for the drug to work.
2. Hand hygiene, privacy, and a clean field for new supplies.
3. Gloves on; remove the old dressing; fold contaminants inward; discard.
4. Change gloves before you touch the clean dressing or the open bottle.
5. Cleanse per plan; do not cut foam or gauze over the open wound (loose fibers).
6. Pack loosely if packing is ordered; date, time, and initial the outer dressing.

Watch one change. If the nurse sets dirty gauze on the sterile pad, stop and reset. Skill check-offs belong in the education record.

Photos support the note; they do not replace it. Teach: obtain consent the way the facility requires; use a secure device, not a personal camera roll; exclude faces, room numbers, and wristbands; include a measurement guide; match distance and lighting; store only in the approved location. If two photos disagree with the bedside measurement, believe the bedside measurement and retake the photo. A photo policy that nobody can recite at 02:00 is not a policy.

When to call the CWCN

Post a short list: new full-thickness loss or suspected deep-tissue pressure injury; a wound that is not tracking toward the documented goal; disagreement about stage versus MASD; a wet-to-dry or heat-lamp order on a granulating or palliative wound; spreading redness, crepitus, or systemic signs; device-related marks that do not resolve; need for a support-surface or offloading change. New graduates should call early. Physicians should call when they want a dressing that matches the goal rather than a default gauze order.

Close the in-service with one role-play: the CNA reports moisture, the new graduate describes without forcing a stage, and you rewrite the wet-to-dry order in front of the team.
