AIRWAY MANAGEMENT &
MECHANICAL VENTILATION EXAM
QUESTIONS AND ANSWERS 100% PASS
What is the purpose of an artificial airway? - ANS To bypass upper airway obstructions and
maintain a patent airway.
Rationale: Ensures ventilation and oxygenation in patients who cannot maintain an open airway.
What are the two main types of artificial airways? - ANS Endotracheal (ET) tube and
tracheostomy.
Rationale: ET tubes are temporary; tracheostomies are longer-term.
What are indications for artificial airway placement? - ANS Upper airway obstruction, apnea,
risk of aspiration, ineffective secretion clearance, respiratory distress.
Rationale: These prevent adequate ventilation or airway protection.
How is an endotracheal (ET) tube inserted? - ANS Via mouth or nose into the trachea.
Rationale: Provides direct access for mechanical ventilation.
Why are there numbers printed on ET tubes? - ANS To mark depth and ensure correct
positioning.
Rationale: Prevents mainstem bronchus intubation or accidental extubation.

, What is the purpose of the ET tube cuff? - ANS Keeps the tube in place and prevents air leaks
or aspiration.
Rationale: Inflated cuff seals the airway during positive pressure ventilation.
What is the advantage of oral ET intubation? - ANS It can be secured rapidly, reduces work of
breathing, and allows easier secretion removal.
Rationale: Larger tube diameter decreases airway resistance.
When is nasal ET intubation contraindicated? - ANS With facial or basilar skull fractures.
Rationale: Risk of intracranial insertion or trauma.
What position is used for intubation? - ANS The "sniffing position" (head back, nose up).
Rationale: Aligns airway structures for easier visualization.
What is rapid sequence intubation (RSI)? - ANS Concurrent administration of sedative and
paralytic drugs for fast intubation.
Rationale: Minimizes aspiration and airway trauma risk.
What should be done before intubation? - ANS Preoxygenate with 100% O₂ via bag-valve
mask.
Rationale: Prevents hypoxemia during the procedure.
What is the maximum time allowed per intubation attempt? - ANS Less than 30 seconds.
Rationale: Prolonged attempts increase risk of hypoxia.
