Accepted Answer

Proliferation/repair phase

Question 4

A patient with diabetes develops a foot ulcer. Which of the following factors is most likely to impede wound healing in this patient?

Accepted Answer

Peripheral arterial disease and neuropathy

Question 5

Which of the following is a primary function of the skin that is directly related to the prevention of infection?

Accepted Answer

Acts as a barrier to microorganisms and ultraviolet rays

Question 6

A patient is at risk for pressure injury due to immobility. Which intervention is most effective in preventing pressure injuries?

Accepted Answer

Turning and repositioning the patient every two hours

Question 7

Which of the following wound types is most likely to heal by secondary intention?

Accepted Answer

A large, open burn wound requiring tissue replacement

Question 8

A nurse observes a patient’s wound with full-thickness tissue loss, visible subcutaneous fat, and rolled wound edges, but no exposed bone or muscle. According to pressure injury staging, this wound is classified as:

Accepted Answer

Stage 3

Question 9

Which laboratory value below indicates a patient is at nutritional risk for developing a pressure injury?

Accepted Answer

Prealbumin $$\u003c 15\ 	ext{mg/dL}$$

Question 10

A patient’s wound is covered with dry, black, leathery tissue. What is the recommended action for stable eschar on the heel?

Accepted Answer

Leave the eschar intact if it is dry, adherent, and without erythema or fluctuance

Question 11

Which of the following best explains why excessive moisture increases the risk of skin breakdown?

Accepted Answer

Moisture creates an environment for microorganism growth and maceration.

Question 12

A patient with a surgical wound is prescribed negative pressure wound therapy (NPWT). Which of the following is a contraindication for NPWT?

Accepted Answer

Active bleeding or exposed blood vessels

Question 13

Which of the following statements about wound healing is correct?

Accepted Answer

Adequate nutrition and oxygenation are essential for all phases of wound healing.

Question 14

A patient’s wound is healing by tertiary intention. Which of the following best describes this process?

Accepted Answer

The wound is left open for several days to allow edema or infection to resolve, then closed.

Question 15

Which of the following is a systemic factor that can delay wound healing?

Accepted Answer

Immunosuppression due to disease or medication

Question 16

A nurse is teaching a patient about heat therapy. Which of the following is a potential systemic effect of applying heat to a large area for an extended period?

Accepted Answer

Hypovolemic shock due to decreased blood flow to other body parts

Question 17

A patient with a chronic wound is prescribed hyperbaric oxygen therapy (HBOT). What is the primary mechanism by which HBOT promotes wound healing?

Accepted Answer

It delivers 100% oxygen under pressure, increasing oxygen dissolved in plasma and stimulating angiogenesis.

Question 18

A patient’s wound is draining a thick, foul-smelling, dark yellow fluid. This type of drainage is best described as:

Accepted Answer

Purulent

Question 19

A nurse is caring for a patient with a pressure injury over the sacrum. Which of the following is the most important initial step in wound management?

Accepted Answer

Remove necrotic tissue to promote healing.

Question 20

A patient with a wound is prescribed a transparent film dressing. Which of the following is an advantage of this dressing type?

Accepted Answer

It allows visualization of the wound while providing a waterproof barrier.
