Question 1

Which of the following is a contraindication to nasopharyngeal airway insertion?

Accepted Answer

Suspected basilar skull fracture

Answer

Patient is unconscious

Answer

Patient has no gag reflex

Answer

Oropharyngeal airway cannot be tolerated

Question 2

In a patient with a cardiac arrest, a sudden rise in PETCO2 to 35–40 mmHg during CPR most likely indicates:

Accepted Answer

Return of spontaneous circulation (ROSC)

Answer

Hyperventilation by the rescuer

Answer

Correct ETT placement confirmed

Answer

Metabolic alkalosis developing

Question 3

What is the appropriate action if PETCO2 is persistently below 10 mmHg after 20 minutes of CPR in an adult?

Accepted Answer

Consider terminating resuscitation efforts

Answer

Increase ventilation rate to 20 breaths/min

Answer

Administer sodium bicarbonate immediately

Answer

Switch to mouth-to-mouth ventilation

Question 4

During CPR, which action should be avoided to prevent hyperventilation?

Accepted Answer

Delivering breaths faster than 10 per minute with an advanced airway

Answer

Using bag-mask ventilation with two rescuers

Answer

Waiting for visible chest fall before next breath

Answer

Maintaining a 30:2 compression-to-ventilation ratio without an advanced airway

Question 5

The cricoid pressure (Sellick maneuver) during intubation is currently:

Accepted Answer

Not routinely recommended as it may worsen laryngeal view

Answer

Mandatory for all emergency intubations per AHA guidelines

Answer

Required only in pediatric patients

Answer

Proven to prevent aspiration in all patients

Question 6

Which of the following best describes the two-thumb encircling technique during bag-mask ventilation?

Accepted Answer

It is preferred over the C-E clamp in two-rescuer CPR for better mask seal

Answer
