A patient is intubated and the capnography waveform shows a rising baseline between breaths. This pattern most likely indicates:
Answer: Rebreathing of CO2 due to exhausted CO2 absorber or obstructed expiratory valve
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.
Which formula is used to estimate the appropriate ETT size for a pediatric patient?
Answer: (Age / 4) + 4
The standard formula (Age/4) + 4 estimates the appropriate uncuffed ETT internal diameter in millimeters for children older than 2 years.
After intubation, breath sounds are heard only on the right side. The paramedic should first:
Answer: Withdraw the ETT 1–2 cm and reassess breath sounds
Unilateral breath sounds after intubation most commonly indicate right mainstem intubation; withdrawing the tube 1–2 cm typically corrects this.
Which sedative agent used in RSI is known for maintaining cardiovascular stability and providing analgesia, making it preferred in hypotensive patients?
Answer: Ketamine
Ketamine stimulates catecholamine release, supporting blood pressure, and provides dissociative analgesia, making it advantageous in hypotensive trauma patients.
During a surgical cricothyrotomy, after incising the cricothyroid membrane, the tracheal hook is used to:
Answer: Retract the inferior edge of the thyroid cartilage to stabilize the trachea
The tracheal hook retracts the inferior edge of the thyroid cartilage upward to stabilize the airway and hold the incision open for tube insertion.
A PEEP valve is attached to the BVM during ventilation of a patient with severe pulmonary edema. What does PEEP accomplish?
Answer: Maintains positive airway pressure at end-expiration to recruit alveoli
PEEP prevents alveolar collapse at end-expiration, recruits fluid-filled alveoli, and improves oxygenation in conditions like pulmonary edema and ARDS.
The 'sniffing position' used to optimize laryngoscopic view in adults involves:
Answer: Head extension with neck slightly flexed on a folded blanket
The sniffing position aligns the oral, pharyngeal, and laryngeal axes by flexing the neck on the chest and extending the head at the atlanto-occipital joint.
