Question 1

Which finding indicates right mainstem intubation after ETT placement?

Accepted Answer

Absent breath sounds on the left with unilateral chest rise

Answer

Right mainstem intubation occurs when the tube passes too deeply into the right bronchus, causing absent left breath sounds and right-sided chest rise only.

Question 2

What is the recommended tidal volume for ventilated patients to prevent ventilator-induced lung injury?

Accepted Answer

6–8 mL/kg ideal body weight

Answer

Lung-protective ventilation uses low tidal volumes of 6–8 mL/kg IBW to prevent barotrauma and volutrauma in ventilated patients.

Question 3

Which supraglottic airway device is considered an advanced alternative to BVM ventilation for cardiac arrest?

Accepted Answer

King LT or LMA (laryngeal mask airway)

Answer

Supraglottic airways like the King LT and LMA can be rapidly placed without visualization and provide effective ventilation during CPR.

Question 4

Preoxygenation before RSI is performed to extend the apneic window. What SpO2 target indicates adequate preoxygenation?

Accepted Answer

SpO2 ≥ 93–95% or higher before paralysis

Answer

Adequate preoxygenation aims for SpO2 ≥93–95% or higher, ideally 100%, to maximize oxygen reserves and extend the safe apneic period during RSI.

Question 5

Which complication is indicated by a sudden rise in peak airway pressure in a ventilated patient after ETT placement?

Accepted Answer

Tension pneumothorax, bronchospasm, or tube obstruction

Answer

Sudden high peak airway pressures after intubation suggest tube obstruction, acute bronchospasm, right mainstem intubation, or tension pneumothorax.
