ACLS ACLS Airway Management 2

Question 1

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

Accepted Answer

Suspected basilar skull fracture

Answer

A suspected basilar skull fracture is a contraindication to NPA insertion due to the risk of intracranial placement through a cribriform plate fracture.

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

A sudden significant rise in PETCO2 during CPR is a reliable indicator of ROSC, reflecting restored cardiac output and pulmonary blood flow.

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

A persistently low PETCO2 (<10 mmHg) after 20 minutes of CPR indicates poor prognosis and may support a decision to terminate resuscitative efforts.

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

Hyperventilation increases intrathoracic pressure, reduces venous return, and decreases cardiac output; ventilation rates above 10/min with an advanced airway should be avoided.

Question 5

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

Accepted Answer

Not routinely recommended as it may worsen laryngeal view

Answer

Routine cricoid pressure is not recommended because evidence shows it may impair laryngeal visualization and does not reliably prevent aspiration.
