ACLS ACLS Airway Management

Question 1

What is the preferred initial airway management technique during cardiac arrest before an advanced airway is placed?

Accepted Answer

Bag-mask ventilation

Answer

Endotracheal intubation

Answer

Nasopharyngeal airway only

Answer

Surgical cricothyrotomy

Question 2

When performing bag-mask ventilation during CPR, what is the recommended tidal volume?

Accepted Answer

500–600 mL (enough to produce visible chest rise)

Answer

800–1000 mL for maximum oxygenation

Answer

1200 mL to ensure deep lung inflation

Answer

200–300 mL to avoid hyperventilation

Question 3

After placement of an advanced airway during CPR, what is the recommended ventilation rate?

Accepted Answer

1 breath every 6 seconds (10 breaths/min)

Answer

1 breath every 3 seconds (20 breaths/min)

Answer

1 breath every 2 seconds (30 breaths/min)

Answer

2 breaths every 30 compressions

Question 4

Which waveform capnography value indicates adequate CPR quality and likely myocardial perfusion during resuscitation?

Accepted Answer

PETCO2 ≥ 20 mmHg

Answer

PETCO2 ≥ 10 mmHg

Answer

PETCO2 < 5 mmHg

Answer

PETCO2 ≥ 40 mmHg

Question 5

What is the most reliable confirmation method to verify correct endotracheal tube placement?

Accepted Answer

Waveform capnography

Answer

Auscultation of breath sounds

Answer

Chest rise observation

Answer

Pulse oximetry reading

Question 6

A supraglottic airway device (SGA) is considered an acceptable alternative to endotracheal intubation in ACLS because it:

Accepted Answer

Can be inserted without interrupting chest compressions and provides effective ventilation

Answer

Is more secure than an ETT and has a lower misplacement risk

Answer

Eliminates the need for PETCO2 monitoring

Answer

Is the preferred airway for all cardiac arrests per 2020 guidelines
