Wound Care Certification Exam Wound Care Certification Beginner's Guide 4

Question 1

Which condition is a contraindication to applying compression therapy for a venous leg ulcer?

Accepted Answer

Severe peripheral arterial disease (ABI < 0.5)

Answer

Compression therapy is contraindicated when severe arterial disease is present (ABI < 0.5) because it can critically reduce arterial perfusion and worsen ischemia.

Question 2

A wound care nurse documents 'eschar' in a wound assessment. What is eschar?

Accepted Answer

Stable, dry, black or brown leathery dead tissue

Answer

Eschar is thick, hard, dry, and leathery necrotic tissue that is typically black or dark brown in color, and may require debridement unless on a heel wound with stable dry gangrene.

Question 3

Negative pressure wound therapy (NPWT) promotes wound healing primarily by:

Accepted Answer

Applying continuous or intermittent sub-atmospheric pressure to remove exudate and stimulate granulation

Answer

NPWT (vacuum-assisted closure) applies sub-atmospheric pressure to remove excess fluid, decrease edema, and stimulate perfusion and granulation tissue formation.

Question 4

Which phase of wound healing is characterized by collagen remodeling and scar maturation?

Accepted Answer

Maturation/remodeling phase

Answer

The maturation or remodeling phase begins approximately 21 days after injury and can last up to 2 years, during which type III collagen is replaced by stronger type I collagen.

Question 5

A patient with a diabetic neuropathic ulcer has 'callus' surrounding the wound. What is the most appropriate initial intervention?

Accepted Answer

Debride the callus to allow proper wound assessment and offloading

Answer

Callus removal (debridement) is essential in diabetic neuropathic ulcers because callus increases plantar pressure and obscures wound depth; debridement improves healing outcomes.
