VERSION QUESTIONS AND AN
1. What is the primary function of the stratum corneum?
A. To produce melanin
B. To provide a waterproof barrier
C. To house sensory receptors
D. To generate new skin cells
Correct Answer: B
Rationale: The stratum corneum is the outermost layer of the epidermis,
composed of dead, flattened keratinocytes. Its primary role is to provide a
waterproof, protective barrier against environmental threats, pathogens, and fluid
loss. Option A is incorrect; melanin is produced by melanocytes in the basal layer.
Option C is incorrect; sensory receptors are located in the dermis. Option D is
incorrect; new skin cells are generated in the basal layer of the epidermis.
2. A patient presents with a wound on their sacrum. The wound is full-
thickness, extending to the subcutaneous fat, but does not involve bone,
tendon, or muscle. According to the NPUAP staging system, what stage is
this pressure injury?
A. Stage 1
B. Stage 2
C. Stage 3
D. Stage 4
Correct Answer: C
Rationale: A Stage 3 pressure injury is defined as full-thickness loss of skin,
where adipose tissue is visible in the ulcer, but bone, tendon, or muscle are not
exposed. Option A is incorrect; a Stage 1 injury is non-blanchable erythema of
intact skin. Option B is incorrect; a Stage 2 injury involves partial-thickness loss of
,skin with exposed dermis. Option D is incorrect; a Stage 4 injury involves exposed
bone, tendon, or muscle.
3. Which of the following is the most appropriate initial cleansing agent for a
clean, granulating wound?
A. Hydrogen peroxide
B. Povidone-iodine
C. Normal saline
D. Acetic acid
Correct Answer: C
Rationale: Normal saline (0.9% sodium chloride) is isotonic and does not
damage or impede the growth of new tissue. It is the safest and most effective
choice for cleansing clean, granulating wounds. Options A, B, and D are all
cytotoxic to healthy granulation tissue and can impede the healing process. They
should be used sparingly, if at all, for specific indications like heavy bioburden.
4. A wound has a large amount of necrotic, black, hard eschar covering it.
What type of debridement is the fastest method to remove this tissue?
A. Autolytic
B. Enzymatic
C. Sharp/Surgical
D. Mechanical
Correct Answer: C
Rationale: Sharp or surgical debridement is the fastest method for removing
necrotic tissue, including tough eschar. Option A (autolytic) is the slowest, using
the body's own enzymes. Option B (enzymatic) uses topical agents and is slower
than sharp debridement. Option D (mechanical) is non-selective and can be
painful and slow.
5. What is the primary purpose of a hydrocolloid dressing?
A. To donate moisture to a dry wound
B. To absorb heavy exudate
C. To maintain a moist wound environment and facilitate autolytic
, debridement
D. To deliver topical antibiotics
Correct Answer: C
Rationale: Hydrocolloid dressings are occlusive or semi-occlusive. They
interact with wound exudate to form a gel, which maintains a moist environment
and promotes autolytic debridement of slough and necrotic tissue. Option A is
incorrect; hydrogels are used to donate moisture. Option B is incorrect; alginates
or foams are better for heavy exudate. Option D is incorrect; they do not typically
contain antibiotics unless specially formulated.
6. A patient with diabetes has a neuropathic foot ulcer. What is the most
critical factor in the treatment plan to promote healing?
A. Application of a hydrogel dressing
B. Offloading pressure from the ulcer site
C. Systemic antibiotic therapy
D. Daily whirlpool therapy
Correct Answer: B
Rationale: For a neuropathic foot ulcer, pressure and repetitive trauma are
the primary causes. Offloading is the single most critical intervention to allow the
wound to heal. Option A may be helpful for moisture balance but is secondary to
offloading. Option C is only indicated if there is a clinical infection. Option D,
whirlpool therapy, is generally not recommended as it can macerate the wound
and introduce bacteria.
7. Which of the following best describes a Stage 1 pressure injury?
A. Partial-thickness loss of skin with exposed dermis
B. Full-thickness skin loss with visible adipose tissue
C. Intact skin with non-blanchable erythema
D. Intact skin with blanching erythema
Correct Answer: C
Rationale: The defining characteristic of a Stage 1 pressure injury is intact skin
with a localized area of non-blanchable erythema, which may appear differently in
, darkly pigmented skin. Option A describes a Stage 2 injury. Option B describes a
Stage 3 injury. Option D is incorrect; blanching erythema is a normal reactive
hyperemic response, not a pressure injury.
8. A wound culture is indicated when:
A. A wound is chronic and has been present for over 4 weeks
B. There are clinical signs of infection (e.g., increasing pain, erythema,
purulent drainage)
C. The wound has a small amount of serous exudate
D. Granulation tissue is present
Correct Answer: B
Rationale: Wound cultures should be obtained when there are clinical signs
and symptoms of infection, not just based on chronicity. Option A is incorrect
because many chronic wounds are colonized, not infected. Option C describes a
normal, healing wound. Option D indicates a healthy healing process.
9. What is the term for the separation of wound edges?
A. Dehiscence
B. Evisceration
C. Eschar
D. Slough
Correct Answer: A
Rationale: Dehiscence is the partial or complete separation of the layers of a
surgical wound. Option B, evisceration, is a more severe complication where
abdominal organs protrude through the wound. Option C, eschar, is thick, leathery
necrotic tissue. Option D, slough, is soft, moist, stringy necrotic tissue.
10.Which dressing is best suited for a wound with significant dead space (a
deep cavity)?
A. Transparent film
B. Hydrocolloid
C. Alginate rope
D. Gauze soaked in saline
