1. Which layer of the skin provides the primary barrier against microbial
invasion?
A. Dermis
B. Epidermis
C. Subcutaneous tissue
D. Fascia
B. Epidermis
The epidermis is the outermost layer of the skin and serves as the
first protective barrier against pathogens and environmental
exposure.
2. What is the primary characteristic of a stage 1 pressure injury?
A. Full-thickness tissue loss
, B. Non-blanchable erythema of intact skin
C. Visible fat layer
D. Bone exposure
B. Non-blanchable erythema of intact skin
Stage 1 pressure injuries present as persistent redness that does not
blanch when pressure is applied, indicating early tissue damage.
3. Which tool is commonly used to assess pressure injury risk?
A. Glasgow Coma Scale
B. Braden Scale
C. APGAR Score
D. Aldrete Score
B. Braden Scale
The Braden Scale evaluates sensory perception, moisture, activity,
mobility, nutrition, and friction/shear to predict pressure injury risk.
4. Which wound type is most associated with arterial insufficiency?
A. Shallow, exudative wound with irregular edges
B. Deep, painful wound on toes or feet
C. Painless sacral ulcer
D. Moist wound with heavy drainage
B. Deep, painful wound on toes or feet
Arterial ulcers are typically painful, located on distal extremities, and
have a “punched-out” appearance due to poor perfusion.
,5. What is the primary goal of moist wound healing?
A. Dry out the wound completely
B. Promote scab formation
C. Accelerate epithelial cell migration
D. Prevent collagen formation
C. Accelerate epithelial cell migration
Moist wound environments facilitate faster cell migration and
healing while reducing tissue desiccation.
6. Which organism is most commonly associated with chronic wound
infection?
A. Escherichia coli
B. Staphylococcus aureus
C. Plasmodium falciparum
D. Candida albicans
B. Staphylococcus aureus
Staphylococcus aureus is a frequent cause of wound infections,
including MRSA strains in chronic wounds.
7. What is the primary purpose of debridement?
A. Reduce pain
B. Remove necrotic tissue
C. Increase scar formation
D. Promote dehydration
B. Remove necrotic tissue
, Debridement removes devitalized tissue to reduce infection risk and
promote healthy wound healing.
8. Which type of wound healing occurs when edges are approximated
with sutures?
A. Secondary intention
B. Tertiary intention
C. Primary intention
D. Delayed closure
C. Primary intention
Primary intention healing occurs when wound edges are closed
surgically, resulting in minimal tissue loss and scarring.
9. What is a common sign of wound infection?
A. Pale wound bed
B. Decreased pain
C. Increased purulent drainage
D. Dry wound bed
C. Increased purulent drainage
Purulent drainage indicates infection and often accompanies
redness, warmth, and swelling.
10. Which dressing is most appropriate for a heavily exudative
wound?
A. Hydrocolloid
B. Alginate
