WOUND, OSTOMY & CONTINENCE NURSING (WOCN) EXAM — 250 Practice
Questions
SECTION 1: WOUND ASSESSMENT AND CLASSIFICATION (Questions 1-50)
1. A nurse is assessing a wound on a patient's sacrum. The wound is characterized by
full-thickness skin loss with visible subcutaneous fat, but bone, tendon, and muscle are
not exposed. There is no undermining or tunneling. According to the NPUAP/EPUAP
staging system, which stage of pressure injury is this?
A. Stage 1 pressure injury.
B. Stage 2 pressure injury.
C. Stage 3 pressure injury.
D. Stage 4 pressure injury.
Answer: C. Rationale: A Stage 3 pressure injury involves full-thickness skin loss with visible
adipose tissue (subcutaneous fat). Bone, tendon, or muscle are not exposed. Undermining and
tunneling may be present. Stage 2 is partial-thickness, Stage 1 is non-blanchable erythema,
and Stage 4 involves exposed bone, tendon, or muscle.
2. A nurse is assessing a wound on a patient's heel. The wound has a black, dry, hard
eschar that is firmly adherent to the wound bed. The surrounding tissue is intact with
no signs of infection. According to the NPUAP/EPUAP staging system, how should this
wound be staged?
A. Stage 2 pressure injury.
, Page 2 of 74
B. Stage 3 pressure injury.
C. Stage 4 pressure injury.
D. Unstageable pressure injury.
Answer: D. Rationale: When a wound is covered with eschar or slough, the depth cannot be
accurately assessed. This wound should be classified as an Unstageable pressure injury until
the eschar is removed. Stable eschar on the heel should not be removed. Unstageable is the
correct staging when the wound bed is obscured.
3. A nurse is evaluating a patient's venous leg ulcer. Which of the following
characteristics is most consistent with a venous ulcer?
A. Location over bony prominences.
B. Pale, dry, and well-defined wound margins.
C. Irregularly shaped, shallow wound with moderate to heavy exudate.
D. Punched-out appearance with minimal exudate.
Answer: C. Rationale: Venous ulcers are typically irregularly shaped, shallow, and located
on the gaiter area of the lower leg (medial malleolus area). They have moderate to heavy
exudate, are associated with edema, and the surrounding skin may be brownish (hemosiderin
staining). Arterial ulcers have pale, dry, punched-out appearance (D). Pressure ulcers occur
over bony prominences (A).
4. A nurse is assessing a patient's foot ulcer. The wound has a pale, dry, well-
demarcated appearance with minimal exudate. The patient reports severe pain in the
foot, especially when elevated. Which type of ulcer is most likely?
A. Venous ulcer.
B. Arterial ulcer.
C. Diabetic neuropathic ulcer.
D. Pressure ulcer.
Answer: B. Rationale: Arterial ulcers are characterized by pale, dry, well-demarcated
wounds with minimal exudate and severe pain, especially with elevation. They typically
occur on the toes, heels, or other pressure points of the foot. Venous ulcers (A) have more
exudate and edema. Diabetic ulcers (C) are often on pressure points but may be less painful
due to neuropathy.
5. A nurse is assessing a patient with a diabetic foot ulcer. The wound is located on the
plantar surface of the foot over the metatarsal head. The wound is surrounded by callus
and has a pale, granular wound bed. Which type of ulcer is this most consistent with?
A. Venous ulcer.
, Page 3 of 74
B. Arterial ulcer.
C. Neuropathic ulcer.
D. Pressure ulcer.
Answer: C. Rationale: Diabetic neuropathic ulcers are typically located on weight-bearing
areas of the foot (plantar surface, metatarsal heads). They are often surrounded by callus and
may have a pale or granular wound bed. Pain may be diminished due to neuropathy. The
location and callus formation are classic features.
6. A nurse is assessing a patient's wound. The nurse notes that the wound edges are
rolled under (epibole). What does this finding indicate?
A. The wound is healing normally.
B. The wound is infected.
C. The wound is stalled in the inflammatory phase.
D. The wound is in the proliferative phase.
Answer: C. Rationale: Epibole (rolled wound edges) indicates that the wound is stalled in the
inflammatory phase. The epithelial cells are unable to migrate across the wound bed,
preventing closure. This requires debridement of the rolled edges to promote healing. Epibole
is not a normal finding.
7. A nurse is documenting a wound assessment. Which of the following is the correct
acronym for a comprehensive wound assessment?
A. PUSH.
B. Bates-Jensen Wound Assessment Tool (BWAT).
C. Braden Scale.
D. Norton Scale.
Answer: B. Rationale: The Bates-Jensen Wound Assessment Tool (BWAT) is a
comprehensive tool for assessing wound characteristics including size, depth, edges, necrotic
tissue, exudate, and surrounding skin. The PUSH tool is for pressure ulcer healing, Braden
and Norton are risk assessment scales.
8. A nurse is assessing a patient's wound and notes the presence of tunneling. Which of
the following is the correct definition of tunneling?
A. A narrow passageway that extends from the wound edge into the subcutaneous tissue.
B. A pocket of fluid under the wound edges.
C. A small area of tissue loss within the wound bed.
D. A narrow passageway that extends from the wound edge in a single direction.
, Page 4 of 74
Answer: A. Rationale: Tunneling is a narrow passageway that extends from the wound edge
into the subcutaneous tissue in any direction. Undermining is a pocket of tissue loss under the
wound edges. Tunneling is assessed by gently inserting a sterile cotton-tipped applicator into
the wound to probe the tract.
9. A nurse is assessing a patient's wound and notes the presence of undermining. Which
of the following is the correct definition of undermining?
A. A narrow passageway that extends from the wound edge into the subcutaneous tissue.
B. A pocket of tissue loss under the wound edges.
C. A small area of tissue loss within the wound bed.
D. A narrow passageway that extends from the wound edge in a single direction.
Answer: B. Rationale: Undermining is a pocket of tissue loss under the wound edges, where
tissue destruction extends beneath intact skin. It is assessed by gently inserting a sterile
cotton-tipped applicator under the wound edges to determine the extent of tissue loss.
Tunneling (A) is a narrow passageway.
10. A nurse is assessing a patient's wound for signs of infection. Which of the following
is a classic sign of wound infection?
A. Pink, healthy granulation tissue.
B. Serous drainage.
C. Purulent drainage with foul odor.
D. Decreased pain.
Answer: C. Rationale: Purulent drainage with foul odor, along with erythema, warmth,
swelling, and increased pain, are classic signs of wound infection. Pink granulation tissue and
serous drainage are normal healing findings. Pain typically increases with infection.
11. A nurse is assessing a patient's wound for biofilm. Which of the following is a
characteristic of biofilm?
A. A single layer of bacteria that is easily treated with antibiotics.
B. A thin, clear layer of exudate on the wound surface.
C. A complex community of bacteria embedded in a protective matrix.
D. A type of necrotic tissue that requires surgical debridement.
Answer: C. Rationale: Biofilm is a complex community of bacteria embedded in a protective
matrix that is resistant to antibiotics and host defenses. It is often associated with chronic,
non-healing wounds. Biofilm requires mechanical disruption (debridement) and topical
antimicrobials for management. It is not easily treated (A).
