CFRN MCQ 2

Question 1

During a rotor-wing transport at 8,000 feet MSL, a patient's endotracheal tube cuff was inflated with air at sea level. What is the most appropriate management?

Accepted Answer

Deflate and reinflate the cuff with saline or water to a pressure of 20–30 cmH2O

Answer

Air-filled cuffs expand at altitude due to Boyle's Law, risking tracheal injury; filling with liquid prevents volume changes.

Question 2

A flight nurse is assessing a patient with a suspected tension pneumothorax. Which finding is MOST specific for this diagnosis in the flight environment?

Accepted Answer

Absent breath sounds on the affected side with hypotension and JVD

Answer

The triad of absent breath sounds, hypotension, and JVD strongly indicates tension pneumothorax requiring immediate needle decompression.

Question 3

Which IV fluid is MOST appropriate for initial resuscitation of a burn patient during aeromedical transport?

Accepted Answer

Lactated Ringer's solution

Answer

Lactated Ringer's is the gold-standard resuscitation fluid for burns as recommended by the Parkland formula.

Question 4

A pediatric patient (15 kg) requires succinylcholine for rapid sequence intubation. What is the correct dose?

Accepted Answer

30 mg (2 mg/kg)

Answer

Pediatric RSI dosing for succinylcholine is 2 mg/kg IV due to children's larger volume of distribution.

Question 5

During scene response to a motor vehicle crash, which mechanism most reliably predicts severe injury requiring trauma center transport?

Accepted Answer

Death of an occupant in the same vehicle

Answer

Death of another occupant in the same vehicle is a CDC field triage criterion indicating a high-energy mechanism linked to severe injury.
