Question 1

Which cellular component is primarily responsible for collagen synthesis during the proliferative phase of wound healing?

Accepted Answer

Fibroblasts

Fibroblasts migrate into the wound bed during the proliferative phase and are the primary cells responsible for synthesizing collagen to rebuild the extracellular matrix.

Question 2

A patient presents with a lower extremity wound that has irregular borders, moderate to heavy exudate, and is located near the medial malleolus. What is the MOST likely etiology?

Accepted Answer

Venous insufficiency ulcer

Answer

Venous insufficiency ulcers typically present near the medial malleolus with irregular borders and moderate to heavy exudate due to venous hypertension.

Question 3

What is the primary purpose of negative pressure wound therapy (NPWT)?

Accepted Answer

To promote granulation tissue formation by applying subatmospheric pressure

Answer

Negative pressure wound therapy applies subatmospheric pressure to promote granulation tissue formation, reduce edema, and increase local blood flow to the wound.

Question 4

A full-thickness burn that appears white or brown, is dry and leathery, and is insensate to pain is classified as what degree?

Accepted Answer

Full-thickness burn

Answer

A full-thickness (third-degree) burn destroys the entire epidermis and dermis, resulting in a white or brown leathery eschar that is insensate due to nerve destruction.

Question 5

Which position should a patient with a burn across the anterior neck maintain to prevent contracture?

Accepted Answer

Neck extension without a pillow

Answer

Neck extension without a pillow is the anti-contracture position for anterior neck burns, as it counteracts the natural pull of scar tissue toward flexion.
