Question 1

Volkmann's ischemic contracture is a devastating complication that most commonly results from:

Accepted Answer

Unrelieved compartment syndrome in the forearm

Answer

Volkmann's ischemic contracture results from untreated compartment syndrome causing ischemic necrosis of forearm muscles, leading to permanent flexion contracture.

Question 2

A cast window is most appropriately cut in order to:

Accepted Answer

Inspect a wound site or assess vascular access

Answer

A cast window is cut to provide direct access to a specific area such as a wound for inspection, or to palpate a pulse when there is concern about vascular status.

Question 3

The dorsalis pedis pulse is most reliably palpated on the:

Accepted Answer

Dorsum of the foot between the first and second metatarsals

Answer

The dorsalis pedis artery crosses the dorsum of the foot between the first and second metatarsals and is the standard site for assessing dorsal foot perfusion.

Question 4

When compartment syndrome is suspected in a casted extremity, the MOST appropriate immediate action is to:

Accepted Answer

Bivalve the cast and notify the physician immediately

Answer

Bivalving (splitting the cast on both sides) along with cutting the underlying padding relieves pressure immediately, while prompt physician notification ensures definitive treatment.

Question 5

Sensation in the first dorsal web space between the first and second toes is supplied by which nerve?

Accepted Answer

Deep peroneal nerve

Answer

The deep peroneal nerve provides sensory innervation exclusively to the first dorsal web space of the foot and is assessed to detect compression at the anterior ankle.
