AMLS Airway Management

Question 1

Which airway adjunct is preferred for an unconscious patient without a gag reflex who cannot be intubated immediately?

Accepted Answer

Oropharyngeal airway (OPA)

Answer

An OPA is appropriate for unconscious patients without a gag reflex to maintain tongue displacement and allow effective BVM ventilation.

Question 2

Which is the most reliable method to confirm correct endotracheal tube placement?

Accepted Answer

Waveform capnography showing consistent ETCO2 waveform

Answer

Continuous waveform capnography is the gold standard for confirming and monitoring ETT placement, as it detects every breath delivered to the lungs.

Question 3

In rapid sequence intubation (RSI), what is the purpose of the defasciculating dose of a non-depolarizing agent before succinylcholine?

Accepted Answer

Prevent fasciculations and associated intracranial and intraocular pressure rise

Answer

A defasciculating dose of a non-depolarizing NMBA blunts the muscle fasciculations from succinylcholine, which can transiently raise ICP and IOP.

Question 4

Which neuromuscular blocking agent is contraindicated in burn patients, crush injury, or hyperkalemia due to risk of fatal hyperkalemia?

Accepted Answer

Succinylcholine

Answer

Succinylcholine causes potassium release from acetylcholine receptors; in burns, crush injuries, or upregulated receptors, this can cause fatal hyperkalemia.

Question 5

What is the LEMON law mnemonic used for in airway management?

Accepted Answer

Predicting difficult laryngoscopy and intubation

Answer

LEMON (Look externally, Evaluate 3-3-2, Mallampati, Obstruction, Neck mobility) is used to predict difficult laryngoscopy before RSI.
