16.3 Modifiable Risk Factors and Resource Access
Key Takeaways
- Knowledge 050102 and skill 050107 cover teaching the factors that change wound course: infection control at home, nutrition, moisture, repositioning, tobacco, glycemic control, and whether the person can actually follow the plan.
- Skill 050106 adds modifiable risks: tobacco cessation, exercise (including a walking program after vascular clearance for claudication), safety such as no heating pads on numb feet, diet, and offloading.
- A heating pad or electric blanket on neuropathic feet causes burns because the person cannot feel the heat; that is a safety teaching item, not a comfort tip.
- Knowledge 050103 is available resources: support and advocacy, supply access, insurance and DME, and post-acute options such as home health, SNF, and outpatient wound clinic.
- If the household cannot afford or obtain the dressing, the plan must change; documenting 'nonadherent' without a cheaper workable option is not education.
16.3 Modifiable Risk Factors and Resource Access
Quick Answer: Teach the habits and hazards that change healing (050102, 050106, 050107): tobacco, exercise (a walking program for claudication only after vascular clearance), safety (no heating pads on numb feet), diet and protein, offloading that is actually worn, glycemic control, moisture, repositioning, and infection control at home. Then teach how to get help (050103): support groups, supply access, insurance and DME, and post-acute options—home health (HH), skilled nursing facility (SNF), outpatient wound clinic. If they cannot afford dressings, the plan must change.
Independent CWCN prep by OpenExamPrep treats "compliance" as a resource and safety problem first. A boot in a closet and an unpaid specialty-foam bill are not mysteries. They are teaching and care-planning failures.
Tobacco, walking, and heat on numb feet
Tobacco cessation is wound teaching, not a lecture about character. Nicotine and carbon monoxide reduce oxygen delivery, worsen peripheral artery disease, and slow collagen. Ask use in a matter-of-fact way every visit. Offer the plan the person will try: quitline (1-800-QUIT-NOW), nicotine replacement if medically appropriate, a prescribing clinician for medication, and a realistic stop date. "Cut down someday" is not a taught skill. Document what was offered and what they chose.
Exercise / walking for claudication. After the vascular team says walking is appropriate, a structured walking program (often supervised exercise therapy in PAD care) can lengthen the distance before cramping. Teach: walk to a moderate cramp, rest, walk again, on a schedule. Do not tell someone with rest pain, gangrene, or an untreated ischemic wound to "walk through it" the same week as an ABI of 0.3. Plantar diabetic ulcers need offloading, not a mall-walking club that loads the ulcer. Vascular OK first; then walking is a taught risk-reduction skill.
Safety: no heating pads on numb feet. Neuropathy and ischemia mean the person cannot feel a burn starting. Heating pads, electric blankets, microwave rice socks, and "warming the ulcer to bring blood" are common, dangerous home ideas. Teach: check bath water with a hand or a thermometer, never a numb foot; no space heaters aimed at the feet; inspect after any warmth they cannot grade. This is 050106 safety awareness, and it prevents a new full-thickness injury.
Diet, protein, glucose, moisture, turning, offloading
Diet and protein. Wounds consume protein. International pressure-injury guidance commonly uses about 1.25–1.5 g of protein per kilogram per day for adults with pressure injuries who are malnourished or at risk, if that matches kidney function and goals of care. Teach food, not only a powder: eggs, dairy if tolerated, beans, fish, meat, oral nutrition supplements when food is not enough. A person with advanced chronic kidney disease needs a dietitian, not a generic high-protein speech. Calories still matter; protein without enough energy is burned as fuel.
Glycemic control. High glucose impairs white-cell function and collagen. Teach the household to keep the diabetes plan (home checks, medications, hypoglycemia signs) as part of wound care. Do not invent one A1C number for every older adult. Do say: "Swings in blood sugar slow this wound. Bring your meter log to clinic." Coordinate with diabetes education when the pattern is the barrier.
Moisture management. Moisture-associated skin damage from urine, stool, sweat, or wound leakage is a modifiable factor. Teach barrier products, absorptive dressings that match drainage, and clothing that is changed when wet. A wet brief left on a sacrum overnight undoes a $40 foam.
Repositioning. Turning every two hours is a starting script for many bedbound people, then individualize (support surface, tissue tolerance, pain, contracture). Heels off the mattress. Small shifts count in a chair: stand-pivot or weight shift if they can. A written clock or a caregiver alarm is the teachable object, not "remember to move."
Offloading adherence. The device only works when it is on during every step. Teach bathroom trips, kitchen trips, and "just to the mailbox." A removable boot that lives by the door is not offloading. If they will not wear it because of stairs, stigma, or balance, change the device or the environment (wheelchair for a short window, instant total contact cast if appropriate, home health). Shame does not increase steps protected.
Infection control at home. Hands, a clean surface, new dressings, trash bagged, no sharing of scissors between people, pets off the field. Teach when to call: spreading redness, fever, new odor, sudden drainage, confusion, blood that will not stop. Do not teach them to finish a leftover antibiotic from a cousin.
| Risk you can change | What to teach | Trap to name |
|---|---|---|
| Tobacco | Quit plan, quitline, medication options | "I only smoke outside, so the wound is fine" |
| Claudication walking | After vascular OK, walk-rest-walk on a schedule | Walking on rest pain or an unloaded ischemic ulcer |
| Numb feet | No heating pad, no electric blanket on the feet | "Warmth brings blood" |
| Protein / calories | Food first, supplement if needed, dietitian if CKD | Powder without food access |
| Offloading | Boot or cast on for every step | Bathroom exceptions |
| Glucose | Meter, meds, hypo signs as wound care | "The wound nurse doesn't do diabetes" |
| Moisture / turning | Barrier, dry brief, turn clock | Foam dressing on a wet, unturned sacrum |
Resources: if they cannot get the dressing, rewrite the plan
Support and advocacy. Diabetes education, PAD or amputation support, caregiver groups, social work, Area Agency on Aging, faith-community nurses if the person wants them. Isolation is a healing risk; a group is not a luxury add-on.
Supply access. Count what is in the house. Teach how to order, how long shipping takes, and which items are not interchangeable (do not substitute a kitchen paper towel for a prescribed contact layer). Manufacturer samples are a bridge, not a clinic business model.
Insurance and DME. Durable medical equipment and surgical dressings under Medicare Part B (and many other payers) usually need a qualifying wound, an order, and frequency documentation. Quantity limits and prior authorization are real. Teach the household who bills, what a denial means, and that an appeal or a different covered product is part of your job. Compression garments, walkers, and offloading devices each have their own rules; guesswork creates gaps.
Post-acute. Home health when the person is homebound and needs skilled nursing or therapy. SNF when 24-hour nursing or a stay is required to complete the plan. Outpatient wound clinic for procedures, total contact casts, and weekly reassessment when they can travel. Name the option that matches function, not the option that is convenient for the hospital census.
If they cannot afford dressings, you do not keep writing the same specialty list and label them nonadherent. You change the plan: a lower-cost dressing they can buy this week, a frequency they can staff, home health to bring supplies, Medicaid or charity care, a covered DME product, or clinic application until supply is stable. Document the barrier and the new plan. Education without a obtainable product is theater.
Scenario: Ms. Cole's closet boot and unpaid foam
Ms. Cole, 64, has a plantar diabetic ulcer, smokes 10 cigarettes a day, A1C last checked 10.2%, and keeps a heating pad on her feet "for circulation." The removable boot is by the door. She cancelled the last two visits because the foam dressing was $48 each and her DME claim denied. She lives alone.
Education that matches the blueprint: stop the heating pad today (safety). Tobacco: a quit plan, not a scolding. Glucose: meter and diabetes-education referral as wound teaching. Offloading: the boot goes on for bathroom and kitchen, or the device changes. Walking is not the first prescription on an un-offloaded plantar ulcer; vascular and offloading come first. Resources: social work for DME appeal and a covered or affordable dressing this week; home health if she is homebound and skilled need is present; wound clinic for weekly offloading if she can travel. Rewrite the dressing to something she can obtain. Show-me: she puts the boot on and walks to the sink. If she cannot pay for foam Friday, Friday's plan is already wrong.
A person with diabetic neuropathy wants to use a heating pad on the feet to "bring blood to the wound." What should the nurse teach?
A clinic plan lists a specialty foam the patient cannot buy, and the DME claim was denied. What is the correct next education and planning step?
Which walking-program teaching is appropriate?
A homebound adult cannot perform daily dressing changes and has no reliable caregiver. Which resource teaching belongs in the plan?
