, Question 1
A patient with a chronic venous leg ulcer has been using an Unna boot. Which
mechanism best explains its therapeutic effect?
A. Provides sustained compression and moisture retention
B. Delivers topical antibiotics to the wound bed
C. Stimulates collagen synthesis via zinc oxide
D. Creates a negative pressure environment
Correct Answer: A - Provides sustained compression and
moisture retention
RATIONALE
The Unna boot provides sustained compression and maintains a moist
wound environment, which promotes venous return and healing. It
does not deliver antibiotics, stimulate collagen directly, or create
negative pressure.
Question 2
Which phase of wound healing is primarily characterized by the deposition of
granulation tissue and angiogenesis?
A. Hemostasis
B. Inflammatory
C. Proliferative
D. Maturation
Correct Answer: C - Proliferative
RATIONALE
The proliferative phase involves fibroblast migration, angiogenesis,
and granulation tissue formation. Hemostasis and inflammation occur
earlier, while maturation involves remodeling.

, Question 3
A wound has a high bacterial burden but no signs of invasive infection. Which
intervention is most appropriate?
A. Systemic antibiotics
B. Topical antimicrobial dressing
C. Surgical debridement
D. Negative pressure wound therapy
Correct Answer: B - Topical antimicrobial dressing
RATIONALE
High bacterial burden without invasive infection is managed with
topical antimicrobials to reduce bioburden. Systemic antibiotics are
for invasive infection; debridement may be needed but topical is
first-line for localized burden.
Question 4
Which of the following best describes the concept of 'TIME' in wound bed
preparation?
A. Tissue, Infection, Moisture, Edge
B. Temperature, Infection, Moisture, Exudate
C. Tissue, Inflammation, Moisture, Environment
D. Trauma, Infection, Moisture, Edema
Correct Answer: A - Tissue, Infection, Moisture, Edge
RATIONALE
TIME stands for Tissue management, Infection/inflammation control,
Moisture balance, and Edge advancement. It is a framework for
wound bed preparation.

, Question 5
A patient with a pressure injury has a wound bed with 50% slough. Which
debridement method is most selective and appropriate for this patient?
A. Sharp debridement
B. Enzymatic debridement
C. Autolytic debridement
D. Mechanical debridement
Correct Answer: B - Enzymatic debridement
RATIONALE
Enzymatic debridement using collagenase is selective for necrotic
tissue and effective for slough. Sharp debridement is non-selective and
may damage healthy tissue; autolytic is slow; mechanical is
non-selective.
Question 6
Which dressing is most appropriate for a wound with heavy exudate and no
infection?
A. Hydrocolloid
B. Transparent film
C. Foam dressing
D. Hydrogel
Correct Answer: C - Foam dressing
RATIONALE
Foam dressings are highly absorbent and suitable for heavy exudate.
Hydrocolloids and transparent films are for low exudate; hydrogels
add moisture.
