A nurse is caring for a client who has severe depression and is scheduled to receive electroconvulsive therapy. The nurse should recognize that the client will receive succinylcholine to prevent which of the following adverse effects?

Choice A reason: Aspiration is a risk during ECT due to anesthesia, but succinylcholine, a neuromuscular blocker, does not prevent it. Anti-aspiration measures like fasting or airway management are used, as succinylcholine targets muscle paralysis, not gastrointestinal or respiratory protection. Choice B reason: Elevated blood pressure is a common ECT side effect due to sympathetic stimulation, but succinylcholine does not address it. Antihypertensives or beta-blockers are used to manage cardiovascular responses, as succinylcholine’s role is limited to neuromuscular effects during ECT. Choice C reason: Decreased heart rate may occur post-ECT due to vagal stimulation, but succinylcholine does not prevent it. Atropine or other anticholinergics are used to manage bradycardia, as succinylcholine’s paralytic effect targets skeletal muscles, not autonomic cardiac regulation. Choice D reason: Succinylcholine is administered during ECT to prevent muscle contractions during induced seizures, reducing injury risk like fractures. As a depolarizing neuromuscular blocker, it paralyzes skeletal muscles, ensuring safety by minimizing physical convulsion effects while allowing therapeutic brain stimulation.
