ERABORATION
True or False? Severe respiratory acidosis is a cause of cardiac arrest
that requires immediate treatment. - CORRECT ANSWER True
True or False? Succinylcholine is a depolarizing neuromuscular
blocking agent used as a continuous infusion to facilitate mechanical
ventilation in patients with acute respiratory distress syndrome. -
CORRECT ANSWER False
Which of the following is the best explanation of the mechanism of
succinylcholine, a depolarizing neuromuscular blocking agent?
A. It breaks down and inactivates acetylcholine.
B. It competes with acetylcholine for the nicotinic receptors at the
neuromuscular junction.
C. It causes depolarization at the motor endplate so receptors cannot
react with acetylcholine. - CORRECT ANSWER It causes
depolarization at the motor endplate so receptors cannot react with
acetylcholine
