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

Cricoid pressure occludes the esophagus against the vertebral body to reduce the risk of passive regurgitation during intubation, though its routine use is debated.

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

Bilateral chest rise and equal breath sounds with minimal air leak confirm appropriate supraglottic airway placement.

Question 3

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

Accepted Answer

100% oxygen (FiO₂ = 1.0)

Answer

During cardiac arrest resuscitation, 100% oxygen should be used to maximize oxygen delivery to vital organs.

Question 4

How should ventilation be adjusted after ROSC to prevent hyperoxia?

Accepted Answer

Titrate FiO₂ to maintain SpO₂ 92–98%

Answer

After ROSC, titrate FiO₂ to maintain SpO₂ of 92–98% to avoid both hypoxia and hyperoxia-related injury.

Question 5

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

Accepted Answer

One rescuer uses both hands in E-C clamp technique to seal mask; second rescuer squeezes bag

Answer

In two-rescuer BVM, the first rescuer uses the E-C clamp with both hands for an effective mask seal while the second rescuer squeezes the bag.
