Question 1

A patient with a Wagner Grade 3 diabetic foot ulcer most likely has which clinical finding?

Accepted Answer

Deep abscess or osteomyelitis

Answer

Wagner Grade 3 indicates a deep ulcer complicated by abscess, osteomyelitis, or joint sepsis, distinguishing it from Grade 2 (tendon/capsule) and Grade 4 (gangrene).

Question 2

Which radiographic finding is most specific for osteomyelitis underlying a diabetic foot ulcer?

Accepted Answer

Cortical destruction on plain X-ray

Answer

Cortical bone destruction on plain X-ray is the most specific radiographic finding for osteomyelitis, though MRI remains more sensitive overall.

Question 3

Negative pressure wound therapy (NPWT) is contraindicated in which wound type?

Accepted Answer

Wounds with untreated osteomyelitis

Answer

NPWT is contraindicated in wounds with untreated osteomyelitis because it can spread infection and does not substitute for adequate bone debridement and antibiotic therapy.

Question 4

Which organism is most commonly the primary pathogen in early, acute, non-limb-threatening diabetic foot infections?

Accepted Answer

Staphylococcus aureus

Answer

Staphylococcus aureus (including MRSA) is the predominant organism in acute, non-limb-threatening diabetic foot infections.

Question 5

A patient's wound shows 80% red granulation tissue and 20% yellow slough. Which treatment approach best accelerates healing?

Accepted Answer

Selective debridement of slough and moist wound dressing

Answer

Selective debridement of remaining slough combined with a moist wound dressing optimizes the healing environment and removes barriers to epithelialization.
