CPR Advanced Airway Management 3

Question 1

Which device is considered the gold standard for confirming endotracheal tube placement in the prehospital setting?

Accepted Answer

Continuous waveform capnography

Answer

Continuous waveform capnography is the gold standard for confirming and monitoring ETT placement, providing real-time CO2 waveforms.

Question 2

A King LT supraglottic airway is inserted, and you are unable to ventilate. What is the most likely cause?

Accepted Answer

The tube was inserted too shallowly

Answer

Shallow insertion of the King LT positions the distal cuff above the glottis rather than in the esophagus, obstructing ventilation.

Question 3

Which medication used in RSI is contraindicated in patients with burns covering more than 10% BSA, crush injuries, or prolonged immobilization?

Accepted Answer

Succinylcholine

Answer

Succinylcholine causes massive potassium release via upregulated acetylcholine receptors in denervated/damaged muscle, risking lethal hyperkalemia.

Question 4

During needle cricothyrotomy, the needle is inserted through the cricothyroid membrane and angled:

Accepted Answer

45 degrees caudad (toward the feet)

Answer

The needle is angled 45 degrees caudally (toward the feet) to direct it into the tracheal lumen and avoid the vocal cords.

Question 5

A patient in cardiac arrest has an LMA in place. During CPR, you notice gastric contents in the LMA tube. You should:

Accepted Answer

Remove the LMA and insert an ETT after pre-oxygenation

Answer

Regurgitation through an LMA indicates inadequate airway protection; the LMA should be removed and a definitive airway (ETT) established.
