Section 1: Airway, Respiration, and Ventilation (14 questions)
1. A 72-year-old male has labored breathing, use of accessory muscles, and an SpO₂ of 84% on
room air. He can speak 2–3 word sentences. You should:
• A) Apply a nasal cannula at 4 L/min
• B) Assist ventilations with a BVM and supplemental oxygen
• C) Place in the recovery position
• D) Apply a non-rebreather at 15 L/min
Answer: D – He is hypoxic but breathing spontaneously with adequate tidal volume; NRB is first-line.
2. A patient has gurgling respirations and vomitus in the mouth. Your immediate action:
• A) Insert an OPA
• B) Suction with a rigid (Yankauer) catheter
• C) Place in the prone position
• D) Begin BVM ventilations
Answer: B – Gurgling indicates fluid in the airway; suction first.
3. A 6-month-old has a respiratory rate of 65, nasal flaring, and grunting. The best initial oxygen
delivery is:
• A) Non-rebreather mask
• B) Blow-by oxygen
• C) Nasal cannula at 2 L/min
• D) BVM ventilation
Answer: B – Infants tolerate blow-by better; avoid distress from masks.
,4. You hear stridor in a 3-year-old who is drooling and sitting upright. You should:
• A) Lay the child supine
• B) Inspect the throat with a tongue depressor
• C) Transport immediately with parent calm
• D) Attempt blind finger sweep
Answer: C – Suspect epiglottitis; do NOT agitate or examine the airway.
5. A patient has a tracheostomy tube and is in respiratory distress. The inner cannula is clogged.
Your first action:
• A) Remove and replace the inner cannula
• B) Ventilate over the stoma with a pediatric mask
• C) Cut the tube shorter
• D) Suction through the outer cannula
Answer: A – Removing a clogged inner cannula restores the airway.
6. An adult patient has a facial burn, singed nasal hairs, and sooty sputum. You should:
• A) Apply an NRB at 15 L/min
• B) Prepare for early intubation
• C) Place a nasal cannula
• D) Suction oropharynx for 30 seconds
Answer: B – Signs of inhalation injury; airway swelling may occur rapidly.
7. During BVM ventilation, you see the stomach enlarging. This is most likely due to:
• A) Too rapid ventilation rate
• B) Inadequate mask seal
• C) Excessive tidal volume
• D) High oxygen concentration
Answer: C – Excessive volume/pressure forces air into the stomach (gastric distension).
8. A patient has agonal respirations at 4 breaths/min and a palpable pulse of 50. You should:
, • A) Start chest compressions
• B) Ventilate at 10–12 breaths/min
• C) Apply an AED
• D) Give oxygen via NRB
Answer: B – Respiratory arrest with a pulse requires BVM ventilations.
9. A 45-year-old has sudden dyspnea, sharp chest pain, and hemoptysis after knee surgery 2
weeks ago. SpO₂ 88%. You suspect:
• A) Pneumothorax
• B) Pulmonary embolism
• C) Asthma exacerbation
• D) Pericarditis
Answer: B – Post-surgical + sudden dyspnea + hemoptysis = PE.
10. A 14-year-old with asthma has diminished breath sounds, no wheezing, and is drowsy. This
indicates:
• A) Improvement
• B) Silent chest – impending respiratory failure
• C) Foreign body obstruction
• D) Pneumonia
Answer: B – Silent chest in asthma is a life-threatening emergency.
11. A patient is on a BVM with an SpO₂ of 94%. The heart rate drops from 88 to 42. You should:
• A) Increase ventilation rate
• B) Decrease ventilation rate
• C) Switch to NRB
• D) Check for gastric distension
Answer: B – Bradycardia during BVM may be due to hyperventilation; slow down.
12. Which finding confirms correct BVM ventilation in an adult?
• A) Abdomen rises visibly
