CERTIFIED WOUND OSTOMY CONTINENCE NURSE EXAM
(CWOCN®) COMPREHENSIVE PRACTICE QUESTIONS AND
CORRECT ANSWERS 2026-28 LATEST VERSION
Assessment Exam Overview
This comprehensive 150-question examination mirrors the structure and scope of the
Certified Wound Ostomy Continence Nurse (CWOCN®) certification. It integrates:
• Wound Care (approx. 50 questions) – Etiology, assessment, staging,
pathophysiology, debridement, dressings, adjunctive therapies, pressure
injuries, vascular wounds, diabetic foot ulcers, infection control,
prevention, quality improvement.
• Ostomy Care (approx. 50 questions) – Preoperative marking, postoperative
management, stoma complications, pouching systems, peristomal skin
conditions, patient education, nutrition, pediatric considerations.
• Continence Care (approx. 50 questions) – Urinary/fecal incontinence,
pelvic floor dysfunction, neurogenic bladder/bowel, urodynamics,
behavioral therapies, catheter management, moisture- associated skin
damage, ethical/legal issues, professional standards.
1. A patient presents with a shallow open ulcer with a red-pink wound bed
and no slough. Which stage pressure injury is this?
A. Stage 1
B. Stage 2
C. Stage 3
D. Unstageable
Stage 2 pressure injuries involve partial-thickness skin loss with exposed dermis,
presenting as a shallow open ulcer without slough.
,2
2. A wound with exposed bone and undermining is classified as:
A. Stage 2
B. Stage 3
C. Stage 4
D. Deep tissue pressure injury
Stage 4 injuries involve full-thickness tissue loss with exposed bone, tendon, or
muscle.
3. The gold standard for diagnosing osteomyelitis in a chronic pressure
injury is:
A. ESR
B. X-ray
C. MRI
D. Bone biopsy
Bone biopsy provides definitive microbiologic and histologic confirmation.
4. Which factor most impairs wound healing in diabetic patients?
A. Hypertension
B. Hyperglycemia
C. Hyperlipidemia
D. Anemia
Persistent hyperglycemia impairs leukocyte function and collagen synthesis.
,3
5. The primary purpose of autolytic debridement is to:
A. Remove viable tissue
B. Mechanically irrigate wound
C. Use endogenous enzymes to liquefy necrotic tissue
D. Surgically excise eschar
Autolysis relies on body enzymes under occlusive dressings.
6. A patient with ABI 0.4 presents with lower leg ulcer. Best initial
management?
A. High compression therapy
B. Vascular referral before compression
C. Unna boot
D. Debridement
ABI <0.5 indicates severe arterial disease; compression is contraindicated.
7. Venous ulcers are most commonly located:
A. Toes
B. Lateral foot
C. Medial malleolus
D. Heel
, 4
Venous insufficiency ulcers commonly occur at the medial gaiter region.
