AEMCA Airway Management and Ventilation 5

Question 1

Which of the following BEST describes the purpose of cricoid pressure (Sellick maneuver) during intubation?

Accepted Answer

To compress the esophagus and reduce risk of passive regurgitation

Answer

Cricoid pressure compresses the esophagus against the vertebral body, reducing the risk of passive gastric regurgitation during intubation.

Question 2

What is the correct ventilation rate for an adult patient who has a pulse but is apneic?

Accepted Answer

10–12 breaths per minute

Answer

Current guidelines recommend 10–12 breaths per minute (one breath every 5–6 seconds) for an adult with a pulse but no respirations.

Question 3

A patient's skin color, mental status, and SpO2 are all worsening despite BVM ventilations through an LMA. What should the AEMCA suspect?

Accepted Answer

Improper LMA placement or inadequate seal

Answer

Worsening despite LMA ventilation most commonly results from malposition or inadequate seal, requiring repositioning or a more definitive airway.

Question 4

When selecting an OPA size, the correct method is to measure from the:

Accepted Answer

Corner of the mouth to the earlobe

Answer

OPA size is estimated by measuring from the corner of the mouth to the earlobe (or center of mouth to angle of jaw).

Question 5

A trauma patient has a SpO2 of 88% on 15 L/min non-rebreather mask. Breath sounds are absent on the left. The MOST likely diagnosis is:

Accepted Answer

Left tension pneumothorax

Answer

Absent unilateral breath sounds with hypoxia despite high-flow oxygen in a trauma patient strongly suggests tension pneumothorax requiring needle decompression.
