ACLS ACLS Airway Management 3

Question 1

When using an oropharyngeal airway (OPA), the appropriate size is determined by measuring from:

Accepted Answer

The corner of the mouth to the earlobe

Answer

The correct OPA size is selected by measuring from the corner of the patient's mouth to the earlobe or the center of the mouth to the angle of the jaw.

Question 2

What is the primary advantage of video laryngoscopy over direct laryngoscopy in emergency intubation?

Accepted Answer

Provides an improved glottic view, particularly in difficult airways

Answer

Video laryngoscopy improves glottic visualization and first-pass success rates, especially in patients with difficult airway anatomy.

Question 3

In ACLS, passive oxygenation during cardiac arrest refers to:

Accepted Answer

Placing a non-rebreather mask on the patient with O2 flowing during CPR without active ventilation

Answer

Passive oxygenation delivers high-flow O2 via a mask to take advantage of the small tidal volumes generated by chest compressions without active ventilation.

Question 4

A patient is intubated and PETCO2 suddenly drops to zero. What is the most likely cause?

Accepted Answer

Esophageal intubation or tube dislodgement

Answer

A sudden drop of PETCO2 to zero indicates no CO2 in exhaled gas, most commonly due to esophageal intubation, tube dislodgement, or circuit disconnection.

Question 5

Which of the following is the recommended oxygen saturation (SpO2) target after ROSC during post-arrest care?

Accepted Answer

94–99%

Answer

Post-ROSC oxygen therapy should target SpO2 of 94–99% to avoid both hypoxia and hyperoxia, which can worsen neurologic outcomes.
