TNCC Airway Management 3

Question 1

In a trauma patient with a Glasgow Coma Scale (GCS) score of 8, which airway management approach is generally indicated?

Accepted Answer

Definitive airway via endotracheal intubation

Answer

A GCS ≤8 indicates inability to protect the airway, making definitive airway management via endotracheal intubation the standard of care.

Question 2

Which sign during bag-valve-mask (BVM) ventilation suggests significant gastric insufflation?

Accepted Answer

Visible epigastric distension and regurgitation risk

Answer

Epigastric distension during BVM ventilation indicates air is entering the stomach, significantly increasing aspiration risk.

Question 3

When performing BVM ventilation in an apneic trauma patient, the recommended tidal volume is approximately:

Accepted Answer

500-600 mL or enough to produce visible chest rise

Answer

Current guidelines recommend 500-600 mL tidal volumes (visible chest rise) during BVM to reduce gastric insufflation while maintaining adequate oxygenation.

Question 4

A trauma patient requiring airway management has a known allergy to succinylcholine. The most appropriate alternative paralytic for RSI is:

Accepted Answer

Rocuronium 1.2 mg/kg

Answer

High-dose rocuronium (1.2 mg/kg) provides intubating conditions comparable to succinylcholine and is the preferred alternative in RSI when succinylcholine is contraindicated.

Question 5

Which finding on chest X-ray after intubation indicates right mainstem bronchus intubation?

Accepted Answer

Left lung atelectasis with right lung hyperexpansion

Answer

Right mainstem intubation selectively ventilates the right lung, causing left lung atelectasis and relative right lung hyperinflation on chest X-ray.
