Which of the following BEST describes the purpose of cricoid pressure (Sellick maneuver) during intubation?
Answer: To compress the esophagus and reduce risk of passive regurgitation
Cricoid pressure compresses the esophagus against the vertebral body, reducing the risk of passive gastric regurgitation during intubation.
What is the correct ventilation rate for an adult patient who has a pulse but is apneic?
Answer: 10–12 breaths per minute
Current guidelines recommend 10–12 breaths per minute (one breath every 5–6 seconds) for an adult with a pulse but no respirations.
A patient's skin color, mental status, and SpO2 are all worsening despite BVM ventilations through an LMA. What should the AEMCA suspect?
Answer: Improper LMA placement or inadequate seal
Worsening despite LMA ventilation most commonly results from malposition or inadequate seal, requiring repositioning or a more definitive airway.
When selecting an OPA size, the correct method is to measure from the:
Answer: Corner of the mouth to the earlobe
OPA size is estimated by measuring from the corner of the mouth to the earlobe (or center of mouth to angle of jaw).
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:
Answer: Left tension pneumothorax
Absent unilateral breath sounds with hypoxia despite high-flow oxygen in a trauma patient strongly suggests tension pneumothorax requiring needle decompression.
Which of the following is a sign of adequate ventilation during CPR without an advanced airway?
Answer: Visible bilateral chest rise with each delivered breath
Visible bilateral chest rise with each ventilation is the primary clinical confirmation that ventilations are effective during CPR.
A 3-year-old child presents in respiratory arrest. Which BVM mask size and ventilation rate are most appropriate?
Answer: Pediatric mask, 20–30 breaths per minute
A pediatric mask sized to fit the child's face is used, and the recommended ventilation rate for children in arrest is 20–30 breaths per minute.
