ACLS ACLS Airway Management and Ventilation 3

Question 1

Which of the following is a sign of right mainstem bronchus intubation?

Accepted Answer

Absent breath sounds on the left side

Answer

Right mainstem intubation causes the ETT to ventilate only the right lung, resulting in absent or decreased breath sounds on the left.

Question 2

What should a rescuer do if a flat capnography waveform is observed after intubation?

Accepted Answer

Assume esophageal intubation and remove the tube immediately

Answer

A persistently flat capnography waveform after intubation strongly suggests esophageal placement; the tube must be immediately removed and the patient re-oxygenated.

Question 3

What is the recommended approach when bag-mask ventilation is difficult due to a poor mask seal?

Accepted Answer

Reposition the head, use two hands, and consider an airway adjunct (OPA/NPA)

Answer

Repositioning the head, using a two-hand technique, and adding an OPA or NPA can significantly improve mask seal and ventilation effectiveness.

Question 4

In ACLS, passive oxygenation during CPR refers to which technique?

Accepted Answer

Allowing the chest recoil to passively draw in oxygen-enriched air through an open airway

Answer

Passive oxygenation during CPR uses chest recoil to draw oxygen-enriched air into the lungs through an open airway without active positive-pressure ventilation.

Question 5

For which patient population is a nasopharyngeal airway (NPA) preferred over an oropharyngeal airway (OPA)?

Accepted Answer

Semi-conscious patients with an intact gag reflex

Answer

An NPA is preferred for semi-conscious patients who have an intact gag reflex because it is better tolerated and less likely to trigger vomiting than an OPA.
