Question 1

A CFRN is preparing to perform cricothyrotomy. The cricothyroid membrane is located between which two structures?

Accepted Answer

Thyroid cartilage superiorly and cricoid cartilage inferiorly

Answer

The cricothyroid membrane lies between the thyroid cartilage superiorly and the cricoid cartilage inferiorly, and is the target for emergency surgical airway.

Question 2

Which ventilator setting should be adjusted first when a transport ventilator alarms for high peak airway pressure in a patient with bronchospasm?

Accepted Answer

Decrease respiratory rate and increase expiratory time (I:E ratio)

Answer

Decreasing respiratory rate and increasing expiratory time allows complete exhalation and prevents air trapping (auto-PEEP) in obstructive disease.

Question 3

A CFRN is transporting a head-injured patient requiring neuroprotective ventilation. What ETCO2 target is most appropriate?

Accepted Answer

35-40 mmHg

Answer

Normocapnia (ETCO2 35-40 mmHg) is the target for neuroprotective ventilation; hypocapnia causes cerebral vasoconstriction and worsens ischemia.

Question 4

During nasotracheal intubation in a spontaneously breathing patient, the CFRN hears peak airflow through the tube. What should be done at this moment?

Accepted Answer

Advance the tube rapidly during peak inspiratory airflow

Answer

Advancing the tube during peak inspiratory flow maximizes the chance of passing the vocal cords as they are most widely abducted during inspiration.

Question 5

What is the primary advantage of using a supraglottic airway device (SGA) such as an LMA over endotracheal intubation in certain flight patients?

Accepted Answer

It can be inserted without direct visualization of the larynx and requires no neuromuscular blockade

Answer

SGAs can be inserted blindly without laryngoscopy or neuromuscular blocking agents, making them valuable rescue airways or when intubation is not feasible.
