Question 1

Which skin tear classification system uses categories 1, 2, and 3 based on tissue loss?

Accepted Answer

ISTAP Skin Tear Classification

Answer

The ISTAP (International Skin Tear Advisory Panel) classification categorizes skin tears into Type 1 (no tissue loss), Type 2 (partial tissue loss), and Type 3 (total tissue loss).

Question 2

What is the MOST common cause of failure in split-thickness skin grafts?

Accepted Answer

Hematoma or seroma formation beneath the graft

Answer

Hematoma and seroma formation beneath split-thickness skin grafts prevent vascular ingrowth (inosculation), which is the most common cause of graft failure.

Question 3

A patient with a non-healing diabetic foot ulcer has transcutaneous oxygen measurement (TcPO2) of 25 mmHg at the wound site. This value suggests:

Accepted Answer

Impaired healing potential requiring further vascular evaluation

Answer

A TcPO2 below 30 mmHg indicates critically impaired tissue oxygenation with poor healing potential, warranting vascular workup and possible revascularization.

Question 4

Which moist wound healing principle does a hydrogel dressing PRIMARILY provide?

Accepted Answer

Donation of moisture to dry wounds

Answer

Hydrogels have a high water content (up to 96%) that donates moisture to dry or minimally exudating wounds, facilitating autolytic debridement.

Question 5

Epibole, also known as 'rolled wound edges' or 'epiboly,' is BEST managed by:

Accepted Answer

Mechanical or sharp disruption of the rolled epithelium

Answer

Epibole requires disruption of the rolled, non-migrating epithelial edges through sharp debridement, curettage, or chemical cauterization to restore lateral cell migration.
