Correct Answers and Rationals
Domain 1: Wound Assessment and Classification (Questions 1-28)
Q1. A patient presents with a wound over the sacrum that is shallow with a
pink/red wound bed. There is no slough or bruising. How should the nurse
document this pressure injury?
• A) Stage 1 Pressure Injury
• B) Stage 2 Pressure Injury
• C) Stage 3 Pressure Injury
• D) Deep Tissue Pressure Injury
Correct Answer: B. Stage 2 Pressure Injury
Rationale: A Stage 2 pressure injury presents as partial-thickness skin loss with
exposed dermis. The wound bed is viable, pink or red, and moist, without slough
or bruising. Stage 1 is intact skin with non-blanchable erythema. Stage 3 involves
full-thickness skin loss with visible subcutaneous fat. Deep Tissue Pressure Injury
presents as intact skin with non-blanchable deep red, maroon, or purple
discoloration .
,Q2. When assessing a wound, what is the best way to differentiate between
granulation tissue and muscle tissue?
• A) Observe for color
• B) Measure temperature difference
• C) Observe for location in the wound
• D) Palpate and gently pinch tissue
Correct Answer: D. Palpate and gently pinch tissue
Rationale: Granulation tissue is soft, friable, and bleeds easily when touched.
Muscle tissue is firmer and contracts when pinched. While color can provide clues
(granulation tissue is red and moist, muscle is darker red), palpation is the
definitive method for differentiation .
Q3. What does "epibole" refer to in wound care?
• A) Hardened tissue surrounding the wound
• B) The rolled or curled edges of a wound that impede healing
• C) New tissue formed during healing
• D) Softening of tissue due to moisture
Correct Answer: B. The rolled or curled edges of a wound that impede
healing
Rationale: Epibole refers to rolled or curled wound edges that prevent epithelial
migration across the wound surface. This condition indicates a chronic, non-
healing wound that may require edge debridement to promote healing .
,Q4. A wound with irregular edges, minimal exudate, and surrounding
hyperpigmentation is MOST consistent with:
• A) Arterial ulcer
• B) Venous ulcer
• C) Pressure injury
• D) Diabetic neuropathic ulcer
Correct Answer: B. Venous ulcer
Rationale: Venous ulcers typically have irregular borders, moderate to heavy
exudate, and surrounding hyperpigmentation (hemosiderin staining from red blood
cell breakdown). They are commonly located at the medial malleolus .
Q5. Which finding BEST differentiates an arterial ulcer from a venous ulcer?
• A) Presence of exudate
• B) Location near ankle
• C) Pain increased with elevation
• D) Presence of edema
Correct Answer: C. Pain increased with elevation
Rationale: Arterial ulcers cause pain that increases with elevation (due to
decreased blood flow when the leg is raised against gravity) and decreases when
the leg is dependent (gravity assists blood flow). Venous ulcers often present with
edema and significant exudate .
, Q6. What is the primary advantage of the clock method of measuring a
wound as opposed to the greatest length by greatest width (GLBGW) method?
• A) GLBGW underestimates wound size and the clock method does not
• B) Clock method is the most commonly used
• C) Clock method requires less precision
• D) Clock method tracks the same site consistently
Correct Answer: D. Clock method tracks the same site consistently
Rationale: The clock method (using 12 o'clock as the patient's head) allows
consistent measurement of the same anatomical location over time, enabling
accurate tracking of wound progression or regression. The GLBGW method may
vary depending on how the clinician orients the wound .
Q7. What does nonblanching erythema indicate regarding pressure ulcer
development?
• A) Normal blood flow response
• B) Impaired blood flow suggesting tissue destruction
• C) Superficial fungal infection
• D) Allergic contact dermatitis
Correct Answer: B. Impaired blood flow suggesting tissue destruction
Rationale: When pressure is applied to an erythematous area, normal skin
becomes white (blanches) as blood is temporarily displaced, then returns to pink.
In nonblanching erythema, the skin does not blanche—indicating impaired blood
