Question 1

A construction worker fell 30 feet and has paradoxical chest wall movement over the right lateral chest. This finding is consistent with:

Accepted Answer

Flail chest

Answer

Flail chest occurs when three or more adjacent ribs are fractured in two or more places, causing a segment to move paradoxically inward with inhalation.

Question 2

Which burn percentage is used as the threshold requiring transport to a burn center per ABA guidelines for a full-thickness burn?

Accepted Answer

Any full-thickness burn

Answer

ABA guidelines recommend burn center referral for any full-thickness burn regardless of size due to complexity of care and risk of complications.

Question 3

You are treating a patient in anaphylactic shock with severe bronchospasm and hypotension. After epinephrine 0.3 mg IM, the patient remains hemodynamically unstable. What is the next appropriate intervention?

Accepted Answer

Repeat epinephrine IM and establish IV access for fluid bolus

Answer

If initial epinephrine IM fails, a repeat dose should be given while establishing IV access for fluid resuscitation to counter vasodilation.

Question 4

During a mass casualty incident using START triage, an adult patient is breathing at 24 breaths/minute, has a radial pulse, and can follow simple commands. This patient is tagged:

Accepted Answer

Yellow (delayed)

Answer

In START triage, a patient breathing >30 or <10 is red; this patient breathes at 24, has a pulse, and is responsive — meeting yellow (delayed) criteria.

Question 5

A patient with a crush injury to the lower extremities is extricated after 4 hours. You should be most concerned about which life-threatening complication upon release?

Accepted Answer

Hyperkalemia and acute renal failure from rhabdomyolysis

Answer

Crush syndrome releases myoglobin and potassium from damaged muscle into circulation, causing hyperkalemia and tubular obstruction leading to renal failure.
