COPR Airway Management and Respiratory Emergencies 2

Question 1

Which laryngoscope blade is most appropriate for a patient with a suspected anterior (anterior larynx) and with an omega-shaped epiglottis?

Accepted Answer

Miller (straight) blade

Answer

The Miller straight blade is preferred for patients with an anterior airway or a floppy omega-shaped epiglottis because it directly lifts the epiglottis to expose the cords.

Question 2

You are ventilating a patient with a BVM and notice gastric distension developing. What is the BEST intervention to reduce aspiration risk while continuing ventilation?

Accepted Answer

Apply cricoid pressure (Sellick maneuver)

Answer

Cricoid pressure compresses the esophagus against the cervical vertebrae, reducing passive regurgitation during BVM ventilation when airway is not secured.

Question 3

A patient with suspected anaphylaxis presents with stridor, hoarse voice, and rapidly developing angioedema. What airway management approach is MOST appropriate?

Accepted Answer

Perform rapid sequence intubation (RSI) early before the airway completely obstructs

Answer

Early RSI is indicated because angioedema can rapidly progress to complete obstruction, making intubation impossible and surgical airway the only option if delayed.

Question 4

Which of the following is the MOST appropriate initial approach to managing a pediatric patient with croup (laryngotracheobronchitis) exhibiting moderate respiratory distress?

Accepted Answer

Nebulized epinephrine and corticosteroids

Answer

Nebulized epinephrine reduces subglottic edema and corticosteroids reduce airway inflammation, making them first-line treatment for moderate croup.

Question 5

During RSI, succinylcholine is contraindicated in which of the following clinical situations?

Accepted Answer

Patient with a history of malignant hyperthermia or crush injury

Answer

Succinylcholine is contraindicated in crush injuries (hyperkalemia risk causing cardiac arrest) and in patients with or at risk for malignant hyperthermia due to potentially fatal muscle rigidity.
