, �Unit 1: Skin Integrity & Wound Care




Question 1
A patient has a wound that is beefy red, bleeds easily, and has a bumpy texture. The
nurse documents this finding as:

 A. Eschar
 B. Slough
 C. Granulation tissue
 D. Purulent drainage

Answer: C

Rationale: Granulation tissue is characterized by a beefy red appearance, bleeds easily,
and has a bumpy/granular texture. It indicates healthy wound healing during the
proliferative phase. Eschar is black/brown necrotic tissue, slough is yellow/white fibrous
tissue, and purulent drainage indicates infection.




Question 2
The nurse is assessing a pressure ulcer that presents as a non-blanchable area of
redness with intact skin. How should the nurse stage this wound?

 A. Stage 1
 B. Stage 2
 C. Stage 3
 D. Stage 4

Answer: A

Rationale: A Stage 1 pressure ulcer is characterized by intact skin with non-blanchable
redness, usually over a bony prominence. The area may also be warm, firm, or painful
compared to surrounding tissue.

, Question 3
A patient has a wound with full-thickness skin loss extending through the dermis to the
underlying fascia, but not through the fascia. The nurse correctly stages this ulcer as:

 A. Stage 1
 B. Stage 2
 C. Stage 3
 D. Stage 4

Answer: C

Rationale: Stage 3 pressure ulcers involve full-thickness skin loss extending through the
dermis to the subcutaneous tissue and underlying fascia. The wound appears as a deep
crater, and tunneling or undermining may be present.




Question 4
Using the RYB wound classification system, a red wound requires which type of
treatment?

 A. Debridement
 B. Cleaning to remove nonviable tissue
 C. Cover with hydrocolloid dressing
 D. Application of heat

Answer: C

Rationale: In the RYB color code system, red wounds (indicating granulation tissue)
should be protected with moist dressings like hydrocolloids to maintain a healing
environment. Yellow wounds require cleaning, and black wounds require debridement.

, Question 5
When collecting a culture from a wound, the nurse should:

 A. Swab the wound edges
 B. Use pus or pooled exudate
 C. Clean the wound first, then culture the clean tissue
 D. Apply pressure to express drainage before culturing

Answer: C

Rationale: Wound cultures should be obtained from clean tissue after cleaning the
wound with normal saline. Pus or pooled exudate contains colonized surface bacteria
and does not accurately reflect the causative organism.




Question 6
A patient's surgical incision has separated with protrusion of internal organs. The nurse
recognizes this as:

 A. Dehiscence
 B. Evisceration
 C. Fistula
 D. Approximation

Answer: B

Rationale: Evisceration is the total separation of all wound layers with protrusion of
internal organs through the incision. This is a surgical emergency requiring immediate
intervention. Dehiscence is partial or complete separation of tissue layers without organ
protrusion.




Question 7
Which assessment finding indicates a wound is healing by primary intention?
