1. Periwound maceration is caused by: → Prolonged exposure of surrounding skin to wound moisture
2. When teaching an ostomy patient about food-related odor management, the nurse should advise that which food DECREASES stomal odor? → Yogurt and buttermilk
3. An unstageable pressure injury is characterized by: → Full-thickness tissue loss covered by slough or eschar obscuring depth
4. Collagen synthesis during wound healing is primarily the responsibility of which cell type? → Fibroblasts
5. Factors that impair wound healing include all of the following EXCEPT: → Adequate tissue oxygenation
6. A wound measuring 4 cm long and 3 cm wide has a surface area of how many square centimeters? → 12 cm²
7. A wound swab culture is most appropriately collected using the: → Levine technique (rotating swab under pressure over 1 cm² of clean tissue)
8. Which vitamin is essential for collagen cross-linking and deficiency of which directly impairs wound healing? → Vitamin C
9. A wound exhibiting the NERDS acronym criteria is best described as having: → Superficial critical colonization that may respond to topical antimicrobials
10. The peristomal skin complication most commonly associated with enzymatic damage from small bowel effluent is: → Irritant contact dermatitis (chemical dermatitis)
11. Which of the following is the most reliable method to confirm biofilm presence in a chronic wound? → Wound biopsy and microscopy
12. Parastomal hernia management includes all of the following EXCEPT: → Immediate surgical repair in all asymptomatic cases
13. Intermittent catheterization (IC) is preferred over indwelling urethral catheterization for long-term bladder management because IC: → Significantly reduces the risk of catheter-associated urinary tract infection (CAUTI)
14. Biofilm in a chronic wound is best characterized as: → A structured polymicrobial community encased in a protective extracellular matrix
15. The recommended daily fluid intake for a continent adult to maintain normal voiding and prevent UTI is approximately: → 1500–2000 mL/day
16. A Stage 3 pressure injury is defined as: → Full-thickness skin loss without exposed fascia, bone, tendon, or muscle
17. A wound care nurse notes that a patient's pressure injury has increased pain, warmth, and new purulent exudate. The FIRST priority intervention is to: → Notify the provider and obtain a wound culture
18. Stress urinary incontinence (SUI) is caused by: → Inadequate urethral sphincter resistance during increased intra-abdominal pressure
19. Polyhexamethylene biguanide (PHMB) is used as a wound antiseptic primarily because it: → Has broad-spectrum antimicrobial action with low cytotoxicity to host cells
20. Hypertrophic scarring differs from keloid scarring in that hypertrophic scars: → Remain within the original wound margins and may regress over time
21. A wound that has been present for more than 30 days without measurable progress toward closure is classified as: → A chronic wound
22. Double incontinence (combined urinary and fecal incontinence) significantly increases the risk of: → Severe incontinence-associated dermatitis (IAD) and pressure injury
23. Which of the following best defines a critically colonized wound? → A wound with bacteria causing tissue damage and delayed healing without systemic signs
24. Which psychosocial issue most commonly affects quality of life in patients with a new ostomy? → Altered body image, fear of odor, and concerns about intimacy
25. Which pressure redistribution device is considered the gold standard for prevention of pressure injuries in high-risk patients? → Active (alternating pressure) support surface
26. Negative pressure wound therapy (NPWT) is contraindicated in wounds with: → Exposed blood vessels, organs, or anastomotic sites
27. The recommended frequency for routine pouch change in a stable ostomy patient is: → Every 3–7 days based on pouching system manufacturer guidelines
28. Bladder training for urge incontinence involves: → Gradually increasing the interval between voids to re-establish normal bladder capacity
29. Convex pouching systems are indicated for patients with: → Retracted or flush stomas and peristomal skin folds causing leakage
30. When caring for a patient with a methicillin-resistant Staphylococcus aureus (MRSA) wound infection, which isolation precaution level is required? → Contact precautions
