TPATC and CFRN Final Exam Practice Questions
and Answers Exam
Q1. During aeromedical transport, a patient develops hypoxia at altitude. Which gas law
explains this phenomenon?
A. Boyle’s Law
B. Dalton’s Law
C. Henry’s Law
D. Charles’s Law
Answer: B. Dalton’s Law
Rationale: Dalton’s Law explains partial pressures of gases. At altitude, reduced partial
pressure of oxygen leads to hypoxia.
Q2. A trauma patient presents with uncontrolled hemorrhage. What is the first priority in
TPATC protocol?
A. Establish IV access
B. Apply direct pressure/tourniquet
C. Administer fluids
D. Secure airway
Answer: B. Apply direct pressure/tourniquet
Rationale: Hemorrhage control precedes airway in TPATC trauma priorities when
bleeding is life-threatening.
Q3. Which intervention best mitigates barotrauma risk during helicopter ascent?
A. Increase FiO₂
B. Insert chest tube before flight
C. Administer bronchodilators
D. Place patient supine
Answer: B. Insert chest tube before flight
Rationale: Expanding trapped air at altitude can cause tension pneumothorax; chest
tube prevents this.
Q4. A patient with suspected spinal injury requires transport. What immobilization is
most appropriate?
A. Soft cervical collar
B. Rigid cervical collar + backboard
C. Sandbags
D. Semi-Fowler’s position
Answer: B. Rigid cervical collar + backboard
Rationale: Full immobilization prevents secondary spinal cord injury during transport.
Q5. Which pharmacologic agent is contraindicated in hypovolemic shock during
transport?
A. Ketamine
,B. Propofol
C. Etomidate
D. Midazolam
Answer: B. Propofol
Rationale: Propofol causes vasodilation and hypotension, worsening hypovolemic
shock.
Q6. CFRN protocols emphasize monitoring for hypoxia due to altitude. Which clinical
sign appears first?
A. Cyanosis
B. Restlessness/confusion
C. Bradycardia
D. Seizures
Answer: B. Restlessness/confusion
Rationale: Neurological changes precede cyanosis in hypoxia recognition.
Q7. In TPATC, the “platinum 10 minutes” refers to:
A. Time to establish IV access
B. Time to secure airway
C. Time to initiate transport
D. Time to control hemorrhage
Answer: C. Time to initiate transport
Rationale: Rapid evacuation within 10 minutes improves trauma survival outcomes.
Q8. Which gas law explains expansion of trapped air in sinuses during ascent?
A. Boyle’s Law
B. Dalton’s Law
C. Henry’s Law
D. Charles’s Law
Answer: A. Boyle’s Law
Rationale: Boyle’s Law: pressure decreases → volume increases, causing sinus
pain/barotrauma.
Q9. A patient with traumatic brain injury requires sedation. Which agent is preferred in
flight?
A. Ketamine
B. Midazolam
C. Propofol
D. Etomidate
Answer: A. Ketamine
Rationale: Ketamine maintains airway reflexes and supports blood pressure, safe in TBI
transport.
Q10. CFRN exam emphasizes “stressors of flight.” Which is not a stressor?
A. Hypoxia
B. Noise
, C. Vibration
D. Hyperthermia
Answer: D. Hyperthermia
Rationale: Stressors include hypoxia, noise, vibration, fatigue, but not hyperthermia.
Q11. TPATC airway management prioritizes:
A. Endotracheal intubation
B. Bag-valve-mask ventilation
C. Surgical cricothyrotomy
D. Oropharyngeal airway
Answer: A. Endotracheal intubation
Rationale: Definitive airway is prioritized in trauma protocols.
Q12. Which oxygen delivery system is most effective at altitude?
A. Nasal cannula
B. Simple face mask
C. Non-rebreather mask
D. Venturi mask
Answer: C. Non-rebreather mask
Rationale: Provides highest FiO₂, compensating for reduced partial pressure at altitude.
Q13. A trauma patient with suspected tension pneumothorax in flight should receive:
A. Needle decompression at 2nd ICS midclavicular
B. Needle decompression at 5th ICS midaxillary
C. Chest tube insertion
D. High-flow oxygen only
Answer: A. Needle decompression at 2nd ICS midclavicular
Rationale: Immediate decompression relieves life-threatening tension pneumothorax.
Q14. CFRN exam highlights “stressors of flight.” Which stressor most affects medication
pharmacokinetics?
A. Noise
B. Vibration
C. Hypoxia
D. Fatigue
Answer: C. Hypoxia
Rationale: Hypoxia alters drug metabolism and tissue perfusion.
Q15. TPATC hemorrhage control includes:
A. IV fluids first
B. Tourniquet application
C. Oxygen administration
D. Pain control
Answer: B. Tourniquet application
Rationale: Tourniquet is lifesaving in uncontrolled extremity hemorrhage.
