Question 1

Which bacteria is MOST commonly isolated from infected diabetic foot ulcers in patients with no prior antibiotic exposure?

Accepted Answer

Staphylococcus aureus

Answer

Staphylococcus aureus is the most frequent causative organism in previously unexposed diabetic foot infections, though MRSA is common in healthcare-associated infections.

Question 2

A wound culture is obtained by the Levine technique. This involves:

Accepted Answer

Rotating a swab with 10 seconds of pressure over 1 cm² of clean wound tissue

Answer

The Levine technique applies firm rotating pressure over a 1 cm² area of clean wound bed for 10 seconds to capture deeper wound tissue organisms rather than surface contaminants.

Question 3

When documenting wound measurements, the MOST clinically consistent method for measuring wound length and width is:

Accepted Answer

Head-to-toe axis by side-to-side axis regardless of wound shape

Answer

Using a consistent head-to-toe by side-to-side orientation eliminates clinician variability and allows accurate serial comparisons over time.

Question 4

A patient with a chronic venous leg ulcer has lipodermatosclerosis of the lower leg. This finding indicates:

Accepted Answer

Chronic venous hypertension causing fibrosis of subcutaneous tissue

Answer

Lipodermatosclerosis is induration and fibrosis of subcutaneous tissue caused by chronic venous hypertension and resulting hemosiderin deposition.

Question 5

Which factor in the local wound environment MOST directly impairs oxygen delivery to healing tissue?

Accepted Answer

Wound edema increasing interstitial fluid pressure

Answer

Edema raises interstitial fluid pressure, compressing capillaries and increasing the diffusion distance for oxygen from vessels to cells.
