Q1. Which skin change is commonly associated with normal aging?
A) Increased epidermal thickness
B) Increased sebaceous-gland activity
C) Thinner skin with reduced elasticity
D) Increased subcutaneous tissue
Correct Answer: C) Thinner skin with reduced elasticity
Rationale: Aging commonly causes thinning of the skin, reduced elasticity,
decreased subcutaneous tissue, and decreased activity of some glands,
making the skin more vulnerable to injury.
Q2. Which assessment finding is most concerning for impaired
tissue perfusion in a skin wound?
A) Warm pink wound edges
B) Dusky wound tissue with delayed capillary refill
C) Small amount of serous drainage
D) Intact surrounding skin
Correct Answer: B) Dusky wound tissue with delayed capillary refill
Rationale: Dusky or poorly perfused tissue and delayed capillary refill can
indicate inadequate blood flow, which impairs healing and increases the risk
of tissue necrosis.
Q3. Which diagnostic procedure is commonly used to identify the
cause of a suspicious skin lesion?
A) Skin biopsy
B) Electrocardiogram
C) Spirometry
D) Bone scan
Correct Answer: A) Skin biopsy
Rationale: A skin biopsy removes a sample of tissue for microscopic
examination and can help distinguish benign, inflammatory, infectious, and
malignant lesions.
Q4. What is the primary purpose of a wound culture?
, A) Determine blood type
B) Identify microorganisms contributing to infection
C) Measure oxygen saturation
D) Determine bone density
Correct Answer: B) Identify microorganisms contributing to infection
Rationale: A wound culture can identify organisms present in an infected
wound and help guide antimicrobial therapy.
Q5. Which skin disorder is characterized by chronic inflammatory
plaques with silvery scales?
A) Intertrigo
B) Psoriasis

C) Consistent sleep
D) Balanced nutrition
Correct Answer: A) Stress
Rationale: Emotional stress is a recognized trigger for psoriasis flares and
may worsen existing skin inflammation.
