Section 1: Respiratory Emergencies (Questions 1–25)
1. A 22-year-old male is experiencing a severe asthma attack. He is in severe
respiratory distress with a silent chest on auscultation. What does this finding
indicate?
A. Mild asthma exacerbation
B. Moderate asthma exacerbation
C. Severe, life-threatening asthma exacerbation
D. The patient is improving
Answer: C
Rationale: A silent chest indicates that airflow is so severely compromised that air
is no longer moving through the airways, resulting in no audible wheezing. This is
a sign of a life-threatening asthma exacerbation requiring immediate intervention,
including BVM ventilation and possible epinephrine administration. The 2025
AHA Guidelines added two new recommendations for adults and children with
life-threatening asthma.
2. A 67-year-old male with a history of COPD presents with increased sputum
production, worsening dyspnea, and a change in sputum color from clear to
yellow-green. What is the most likely diagnosis?
A. Asthma exacerbation
B. COPD exacerbation with possible infection
C. Pulmonary embolism
D. Pneumothorax
Answer: B
,Rationale: Increased sputum production with a change in color (e.g., from clear to
yellow or green) indicates possible infection and COPD exacerbation. This
requires prompt intervention and communication with the patient's physician.
COPD exacerbations are commonly triggered by respiratory infections.
3. A 6-month-old male has a two-day history of low-grade fever, tachypnea,
and wheezing. Auscultation of lung sounds reveals inspiratory and expiratory
wheezes to all lobes bilaterally. You suspect that the patient has:
A. Epiglottitis
B. Pneumonia
C. Croup
D. Bronchiolitis
Answer: D
Rationale: Bronchiolitis is a common lower respiratory tract infection in infants,
most often caused by respiratory syncytial virus (RSV). It presents with low-grade
fever, tachypnea, and diffuse wheezing. Epiglottitis presents with drooling and
stridor. Croup presents with a barking cough and inspiratory stridor. Pneumonia
typically presents with focal crackles and higher fever.
4. A patient with a suspected pulmonary embolism is being transported.
Which diagnostic finding is most consistent with this condition?
A. V/Q mismatch leading to hypoxemia
B. Normal oxygen saturation
C. Bradycardia
D. Hypertension
Answer: A
Rationale: Pulmonary embolism causes V/Q mismatch due to obstruction of
pulmonary arteries, leading to areas of dead space (high V/Q) and areas of shunt
(low V/Q). This results in hypoxemia. The primary mechanism of hypoxemia in
PE is V/Q mismatch.
,5. A 72-year-old female is in respiratory distress with a history of COPD. Her
oxygen saturation is 88% on room air. What is the target oxygen saturation
for this patient?
A. 100%
B. 88–92%
C. 94–98%
D. 85–90%
Answer: B
Rationale: In patients with COPD, the target oxygen saturation is 88–92%.
Excessive oxygen can lead to hypercapnia and respiratory depression in patients
with chronic CO₂ retention. Oxygen should be titrated to the target range rather
than administered at high flow rates indiscriminately.
6. A patient with acute respiratory distress syndrome (ARDS) is being
transported on a ventilator. Which ventilator strategy is most appropriate?
A. High tidal volumes (10–12 mL/kg predicted body weight)
B. Low tidal volumes (4–6 mL/kg predicted body weight) with adequate PEEP
C. Zero PEEP to prevent barotrauma
D. High respiratory rate (30–40 breaths/min) with low tidal volumes
Answer: B
Rationale: Lung-protective ventilation with low tidal volumes (4–6 mL/kg
predicted body weight) and adequate PEEP is the standard of care for ARDS. This
strategy reduces ventilator-induced lung injury and mortality. The ARDSNet
protocol demonstrated significant mortality benefit with this approach.
7. A patient with a suspected tension pneumothorax is being transported.
Which intervention is within the paramedic scope of practice?
A. Needle decompression
B. High-flow oxygen and rapid transport
C. Chest tube insertion
D. Pericardiocentesis
, Answer: A
Rationale: Needle decompression is within the paramedic scope of practice for
tension pneumothorax. Chest tube insertion and pericardiocentesis are physician-
level procedures. High-flow oxygen and rapid transport are also appropriate, but
needle decompression is the definitive prehospital intervention for tension
pneumothorax.
8. A patient with a suspected opioid overdose has a respiratory rate of 6
breaths per minute. According to 2026 AHA guidelines, which intervention is
the priority?
A. Administer naloxone immediately
B. Begin BVM ventilation
C. Apply oxygen via non-rebreather
D. Place the patient in the recovery position
Answer: B
Rationale: The priority for a patient with inadequate breathing is to provide
ventilation. BVM ventilation should be initiated immediately. According to the
AHA 2025 update, naloxone might be considered in suspected opioid-related
cardiac arrests but only after high-quality CPR is underway. In a patient with
respiratory depression but not cardiac arrest, ventilation takes precedence because
it addresses the immediate life threat (hypoxia).
9. 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
