Question 1

The gold standard method for confirming correct endotracheal tube placement after intubation is:

Accepted Answer

Continuous waveform capnography detecting exhaled CO₂

Answer

Continuous waveform capnography is the gold standard for ETT placement confirmation because it provides real-time, objective evidence that ventilated gas contains CO₂ originating from the lungs.

Question 2

High-flow nasal oxygen (HFNO) extends safe apnea time primarily by:

Accepted Answer

Flushing anatomical dead space with oxygen and generating a small CPAP effect

Answer

HFNO extends apneic oxygenation time by continuously flushing dead space with fresh oxygen and creating a small positive pressure (CPAP effect) in the airway, maintaining O₂ delivery even without active breathing.

Question 3

Surgical tracheostomy is typically performed at which level of the trachea?

Accepted Answer

Between the 2nd and 4th tracheal rings

Answer

Surgical tracheostomy is performed between the 2nd and 4th tracheal rings to avoid damage to the cricoid cartilage (subglottic stenosis risk) while remaining within safe upper tracheal territory.

Question 4

The most important step after inserting a double-lumen endobronchial tube (DLT) is:

Accepted Answer

Fiberoptic bronchoscopic confirmation of correct tube position

Answer

Fiberoptic bronchoscopy is mandatory after DLT insertion to confirm correct positioning, as clinical signs alone are insufficient to reliably exclude malposition, which can cause critical failure of lung isolation.

Question 5

The most common immediate complication of percutaneous dilatational tracheostomy (PDT) is:

Accepted Answer

Bleeding at the insertion site

Answer

Bleeding at the tracheostomy site is the most frequent immediate complication of PDT, typically minor and controlled with local pressure, though significant hemorrhage can occur if anterior jugular veins or thyroid vessels are injured.
