SECTION 1: WOUND CARE & PRESSURE INJURIES (Questions 1-25)
Q1. When changing the dressing on a client's partial-thickness wound, the nurse
observes a beefy-red translucent wound bed. Which action should the nurse
take?
A) Contact the primary health care provider immediately
B) Document the findings as abnormal and continue to observe
C) Culture the wound and place the client in isolation
D) Discard the old dressing and cover the wound with a new dressing
✅ Answer: D
Rationale: A beefy-red translucent wound bed indicates healthy granulation
tissue, which is expected in a healing partial-thickness wound. The nurse should
gently discard the old dressing and apply a new dressing using sterile technique.
,Q2. The nurse is teaching about risk factors for wound dehiscence. Which factor
should be included?
A) Altered mental status
B) Nutritional deficiencies
C) Advanced age
D) Immobility
✅ Answer: B
Rationale: Nutritional deficiencies, especially lack of protein, vitamin C, and zinc,
impair wound healing and increase dehiscence risk.
Q3. When collecting a culture from a wound, what should the nurse avoid using?
A) Sterile swab
B) Pus or pooled exudates
C) Normal saline
D) Tissue from the wound edge
✅ Answer: B
,Rationale: The nurse should avoid using pus or pooled exudates because these
represent old, non-viable material that may contain colonizing bacteria rather
than the infectious organism.
Q4. To prevent skin trauma from shearing, what should the nurse consider using?
A) Moisturizing lotion
B) Alcohol-free barrier film
C) Adhesive tape directly on skin
D) Powder
✅ Answer: B
Rationale: Alcohol-free barrier film protects the skin from friction and shearing
forces by creating a protective layer between the skin and external surfaces.
Q5. Using the RYB color code for wounds, a RED wound requires which type of
dressing?
A) Debridement
B) Cleaning to remove nonviable tissue
C) Cover with hydrocolloid dressing
D) Leave open to air
, ✅ Answer: C
Rationale: Red wounds indicate healthy granulation tissue and require protection
with a moist, transparent dressing such as a hydrocolloid or transparent film.
Q6. Using the RYB color code, a YELLOW wound requires which intervention?
A) Cover with hydrocolloid dressing
B) Debridement
C) Cleaning to remove nonviable tissue
D) Apply dry gauze
✅ Answer: C
Rationale: Yellow wounds indicate the presence of slough (nonviable tissue) and
require cleaning to remove the yellow fibrinous material before healing can
proceed.
Q7. Using the RYB color code, a BLACK wound requires which intervention?
A) Cover with hydrocolloid dressing
B) Debridement
C) Apply antimicrobial ointment
