In a trauma patient with a Glasgow Coma Scale (GCS) score of 8, which airway management approach is generally indicated?
Answer: Definitive airway via endotracheal intubation
A GCS ≤8 indicates inability to protect the airway, making definitive airway management via endotracheal intubation the standard of care.
Which sign during bag-valve-mask (BVM) ventilation suggests significant gastric insufflation?
Answer: Visible epigastric distension and regurgitation risk
Epigastric distension during BVM ventilation indicates air is entering the stomach, significantly increasing aspiration risk.
When performing BVM ventilation in an apneic trauma patient, the recommended tidal volume is approximately:
Answer: 500-600 mL or enough to produce visible chest rise
Current guidelines recommend 500-600 mL tidal volumes (visible chest rise) during BVM to reduce gastric insufflation while maintaining adequate oxygenation.
A trauma patient requiring airway management has a known allergy to succinylcholine. The most appropriate alternative paralytic for RSI is:
Answer: Rocuronium 1.2 mg/kg
High-dose rocuronium (1.2 mg/kg) provides intubating conditions comparable to succinylcholine and is the preferred alternative in RSI when succinylcholine is contraindicated.
Which finding on chest X-ray after intubation indicates right mainstem bronchus intubation?
Answer: Left lung atelectasis with right lung hyperexpansion
Right mainstem intubation selectively ventilates the right lung, causing left lung atelectasis and relative right lung hyperinflation on chest X-ray.
Sellick's maneuver (cricoid pressure) during RSI is applied to:
Answer: Reduce passive regurgitation and aspiration risk
Cricoid pressure compresses the esophagus against the vertebral body, reducing passive regurgitation during the apneic period of RSI.
Which supraglottic airway device is considered a RESCUE device but NOT a definitive airway in the TNCC framework?
Answer: King LT or LMA
Supraglottic airways like the King LT or LMA provide temporary ventilation but do not protect against aspiration and are not considered definitive airways.
