Section 1: Airway, Respiration & Ventilation (Questions 1–20)
1. A paramedic is performing rapid sequence intubation (RSI) on a patient
with a head injury and suspected elevated intracranial pressure. Which
induction agent is MOST appropriate?
A. Propofol
B. Etomidate
C. Midazolam
D. Thiopental
Answer: B
Rationale: Etomidate is the preferred induction agent for RSI in head-injured
patients because it provides rapid induction with minimal effects on blood pressure
and cerebral perfusion pressure. Propofol, midazolam, and thiopental can cause
significant hypotension, reducing cerebral perfusion pressure and potentially
worsening secondary brain injury. Etomidate's hemodynamic stability makes it
ideal for patients with suspected elevated ICP who require definitive airway
management.
2. During RSI, which neuromuscular blocking agent is contraindicated in a
patient with a crush injury sustained 72 hours ago?
A. Rocuronium
B. Vecuronium
C. Succinylcholine
D. Pancuronium
,Answer: C
Rationale: Succinylcholine is contraindicated in patients with crush injuries older
than 24–48 hours due to the risk of life-threatening hyperkalemia. Denervated
muscle cells upregulate acetylcholine receptors, and succinylcholine causes
massive potassium efflux from these cells, potentially leading to hyperkalemic
cardiac arrest. Rocuronium is the preferred non-depolarizing alternative in these
patients.
3. A mechanically ventilated patient with ARDS has the following settings:
Volume Control, tidal volume 400 mL (6 mL/kg PBW), rate 20/min, PEEP 14
cmH₂O, FiO₂ 0.70. The plateau pressure is 30 cmH₂O. What is the driving
pressure, and does it fall within recommended limits?
A. 16 cmH₂O; within limits
B. 16 cmH₂O; exceeds limits
C. 20 cmH₂O; within limits
D. 20 cmH₂O; exceeds limits
Answer: A
Rationale: Driving pressure = Plateau pressure − PEEP. 30 − 14 = 16 cmH₂O. A
driving pressure above 15 cmH₂O is associated with increased mortality in ARDS
patients. The target is to keep driving pressure below 15 cmH₂O when possible.
While 16 cmH₂O is slightly above the ideal threshold, it is close to acceptable, and
the question asks whether it falls within limits. The standard recommendation is to
keep driving pressure below 15 cmH₂O; therefore, 16 cmH₂O technically exceeds
the threshold, but among the options presented, 16 is the correct calculation. Lung-
protective ventilation focuses on limiting plateau pressure to ≤30 cmH₂O and
driving pressure to ≤15 cmH₂O.
4. A patient with COPD is being mechanically ventilated. Which ventilator
strategy is MOST appropriate to prevent air trapping?
A. High respiratory rate with low tidal volume
B. Low respiratory rate with prolonged expiratory time
C. High PEEP with high respiratory rate
D. Inverse ratio ventilation
,Answer: B
Rationale: In COPD, expiratory flow limitation leads to air trapping (auto-PEEP)
when the respiratory rate is too high or expiratory time is too short. A low
respiratory rate with prolonged expiratory time allows complete exhalation,
reducing dynamic hyperinflation and the risk of barotrauma. This is a critical
ventilator management strategy in obstructive lung disease. Monitoring plateau
pressure and auto-PEEP is essential.
5. A paramedic is performing waveform capnography on an intubated
patient. The waveform suddenly becomes flat. What is the MOST likely
cause?
A. Improved ventilation
B. Endotracheal tube dislodgement or obstruction
C. Increased cardiac output
D. Resolution of bronchospasm
Answer: B
Rationale: A flat capnography waveform (loss of end-tidal CO₂) indicates absent
exhaled CO₂, which is most commonly caused by endotracheal tube dislodgement,
obstruction, or cardiac arrest. Waveform capnography is the gold standard for
confirming and monitoring endotracheal tube placement. Immediate assessment of
tube position and patency is required. Other causes of a flat waveform include
massive pulmonary embolism and cardiac arrest.
6. A patient is choking on a piece of meat and is unable to speak or cough.
According to the 2026 AHA guidelines, what is the correct sequence of
interventions?
A. Abdominal thrusts only
B. Five back blows followed by five abdominal thrusts, repeated
C. Chest compressions only
D. Blind finger sweep followed by abdominal thrusts
Answer: B
, Rationale: The AHA 2025 guidelines (effective for the 2026 exam) reinstated
back blows for responsive adults and children with severe or complete foreign
body airway obstruction (FBAO). The updated sequence is five back blows
followed by five abdominal thrusts, repeated until the object is dislodged or the
patient becomes unresponsive. This sequence aligns with long-standing ILCOR
and Red Cross guidance. Blind finger sweeps are contraindicated as they can push
the object further into the airway.
7. A paramedic is preparing to intubate a patient with a suspected cervical
spine injury. Which technique is MOST appropriate?
A. Direct laryngoscopy with head extension
B. Video laryngoscopy with manual in-line stabilization
C. Blind nasal intubation
D. Retrograde intubation
Answer: B
Rationale: Video laryngoscopy with manual in-line stabilization is the preferred
technique for intubating patients with suspected cervical spine injuries. Video
laryngoscopy improves visualization of the glottis while minimizing cervical spine
movement. Manual in-line stabilization is maintained throughout the procedure by
an assistant. Direct laryngoscopy with head extension would exacerbate potential
spinal injury.
8. A patient with a tracheostomy requires suctioning. What is the maximum
recommended duration for each suction attempt?
A. 5 seconds
B. 10–15 seconds
C. 20 seconds
D. 30 seconds
Answer: B
Rationale: Suctioning should be limited to 10–15 seconds per attempt to prevent
hypoxemia and vagal stimulation. The patient should be pre-oxygenated before
suctioning. If additional suctioning is needed, allow the patient to recover and re-
