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

Bilateral decreased breath sounds

Answer

High peak airway pressure with equal breath sounds

Answer

Absent CO₂ on waveform capnography

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

Administer epinephrine and continue CPR

Answer

Increase ventilation rate

Answer

Recheck pulse and continue monitoring

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

Increase ventilation pressure

Answer

Switch immediately to endotracheal intubation

Answer

Use a smaller mask

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

Placing a non-rebreather mask at 15 L/min on an intubated patient without active ventilation

Answer

Delivering oxygen via nasal cannula during chest compressions without bag-mask ventilation

Answer

Giving supplemental O₂ between compression cycles only

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

Deeply unconscious patients with no gag reflex

Answer

Patients with nasal trauma

Answer

Patients with suspected basilar skull fracture

Question 6

What ventilation rate is recommended during two-rescuer CPR with bag-mask ventilation (no advanced airway)?

Accepted Answer

1 breath after every 30 compressions (30:2 ratio)

Answer

1 breath every 6 seconds

Answer

2 breaths every 15 compressions

Answer

Continuous ventilation at 10 breaths/min
