Question 1

What is the purpose of cricoid pressure (Sellick maneuver) during intubation?

Accepted Answer

To reduce the risk of passive regurgitation and aspiration

Answer

To open the vocal cords for easier intubation

Answer

To increase oxygen saturation before intubation

Answer

To stabilize the cervical spine

Question 2

Which sign indicates that a supraglottic airway (e.g., LMA) is appropriately placed?

Accepted Answer

Bilateral chest rise and breath sounds with minimal leak

Answer

End-tidal CO₂ waveform identical to ETT

Answer

No air entry heard over the epigastrium

Answer

SpO₂ above 95%

Question 3

In ACLS, what FiO₂ should be used during resuscitation (before ROSC)?

Accepted Answer

100% oxygen (FiO₂ = 1.0)

Answer

40% oxygen

Answer

21% (room air)

Answer

60% oxygen

Question 4

How should ventilation be adjusted after ROSC to prevent hyperoxia?

Accepted Answer

Titrate FiO₂ to maintain SpO₂ 92–98%

Answer

Continue 100% O₂ indefinitely

Answer

Reduce to room air immediately

Answer

Target SpO₂ above 99%

Question 5

During two-rescuer bag-mask ventilation, how should the mask be held?
