AEMT Airway Management and Ventilation

Question 1

Which airway adjunct is inserted through the mouth and used to keep the tongue from obstructing the airway in an unconscious patient?

Accepted Answer

Oropharyngeal airway

Answer

An oropharyngeal airway (OPA) is inserted through the mouth to prevent the tongue from blocking the airway in unconscious, non-responsive patients.

Question 2

At what rate should you deliver ventilations to an adult patient who is not breathing but has a pulse?

Accepted Answer

10–12 breaths/min

Answer

For an apneic adult with a pulse, AEMT protocols call for rescue breathing at 10–12 breaths per minute (one breath every 5–6 seconds).

Question 3

Which sign is the BEST indicator of correct BVM placement and effective ventilation?

Accepted Answer

Visible chest rise

Answer

Visible bilateral chest rise is the primary clinical indicator that the bag-valve-mask is correctly positioned and ventilations are effective.

Question 4

A supraglottic airway device such as the King LT or LMA is best described as:

Accepted Answer

An advanced airway placed above the glottis to channel air into the trachea

Answer

Supraglottic airways sit above the glottic opening and create a sealed channel that directs ventilations into the trachea without passing through the cords.

Question 5

After inserting a supraglottic airway in a cardiac arrest patient, you should confirm placement by:

Accepted Answer

Auscultating breath sounds and checking waveform capnography

Answer

Auscultating bilateral breath sounds and confirming waveform capnography are the standard methods for verifying supraglottic airway placement.
