Question 1

A patient is intubated and the capnography waveform shows a rising baseline between breaths. This pattern most likely indicates:

Accepted Answer

Rebreathing of CO2 due to exhausted CO2 absorber or obstructed expiratory valve

Answer

A rising baseline on capnography indicates the patient is rebreathing exhaled CO2, often caused by a faulty one-way valve or exhausted absorber in a rebreather circuit.

Question 2

Which formula is used to estimate the appropriate ETT size for a pediatric patient?

Accepted Answer

(Age / 4) + 4

Answer

The standard formula (Age/4) + 4 estimates the appropriate uncuffed ETT internal diameter in millimeters for children older than 2 years.

Question 3

After intubation, breath sounds are heard only on the right side. The paramedic should first:

Accepted Answer

Withdraw the ETT 1–2 cm and reassess breath sounds

Answer

Unilateral breath sounds after intubation most commonly indicate right mainstem intubation; withdrawing the tube 1–2 cm typically corrects this.

Question 4

Which sedative agent used in RSI is known for maintaining cardiovascular stability and providing analgesia, making it preferred in hypotensive patients?

Accepted Answer

Ketamine

Answer

Ketamine stimulates catecholamine release, supporting blood pressure, and provides dissociative analgesia, making it advantageous in hypotensive trauma patients.

Question 5

During a surgical cricothyrotomy, after incising the cricothyroid membrane, the tracheal hook is used to:

Accepted Answer

Retract the inferior edge of the thyroid cartilage to stabilize the trachea

Answer

The tracheal hook retracts the inferior edge of the thyroid cartilage upward to stabilize the airway and hold the incision open for tube insertion.
