NPTE-PTA Integumentary System 1 — Questions and Answers
Question 1: A pressure injury that presents with partial-thickness skin loss with exposed dermis is classified as:
- Stage 1
- Stage 2 (Correct answer)
- Stage 3
- Stage 4
Correct answer: Stage 2
Stage 2 pressure injuries involve partial-thickness skin loss with exposed dermis, appearing as a shallow open ulcer or intact blister.
Question 2: The rule of nines estimates burn surface area. The entire head and neck accounts for:
- 4.5%
- 9% (Correct answer)
- 18%
- 36%
Correct answer: 9%
The head and neck together account for 9% of total body surface area in the rule of nines for adults.
Question 3: Which wound dressing maintains a moist environment and is appropriate for a clean, granulating wound?
- Dry gauze
- Hydrocolloid dressing (Correct answer)
- Wet-to-dry dressing
- Calcium alginate
Correct answer: Hydrocolloid dressing
Hydrocolloid dressings maintain a moist wound environment that promotes granulation and epithelialization.
Question 4: Ankle-brachial index (ABI) below 0.5 indicates:
- Normal circulation
- Mild arterial insufficiency
- Moderate arterial insufficiency
- Severe arterial insufficiency with rest pain risk (Correct answer)
Correct answer: Severe arterial insufficiency with rest pain risk
An ABI below 0.5 indicates severe peripheral arterial disease with critical limb ischemia and high amputation risk.
Question 5: Venous stasis ulcers typically occur at which location on the lower extremity?
- Tips of toes
- Heel
- Medial malleolus and gaiter area (Correct answer)
- Dorsum of foot
Correct answer: Medial malleolus and gaiter area
Venous ulcers classically occur around the medial malleolus and gaiter area due to venous hypertension from incompetent valves.
Question 6: Which type of debridement uses selective enzymatic agents applied to necrotic tissue?
- Sharp debridement
- Autolytic debridement
- Enzymatic debridement (Correct answer)
- Mechanical debridement
Correct answer: Enzymatic debridement
Enzymatic debridement uses topical enzymes such as collagenase to selectively break down necrotic tissue.
