Which symptoms would the nurse expect to assess in a client experiencing serotonin syndrome?

Choice A reason: Hypotension, urinary retention, and blurred vision are not primary features of serotonin syndrome. These may occur in anticholinergic toxicity or other conditions. Serotonin syndrome involves hyperactive autonomic and neurological symptoms due to excessive serotonin, making this choice incorrect. Choice B reason: Dizziness, lethargy, and nausea are non-specific and not hallmark symptoms of serotonin syndrome. While nausea may occur, serotonin syndrome is characterized by more severe symptoms like confusion and tachycardia from serotonin overstimulation, making this choice less accurate. Choice C reason: Serotonin syndrome, caused by excessive serotonin (e.g., from SSRI overdose), presents with confusion, restlessness, tachycardia, and diaphoresis due to overstimulation of serotonin receptors, increasing autonomic and neurological activity. These symptoms reflect the syndrome’s hyperactive state, making this the correct choice. Choice D reason: Hypomania, arrhythmias, and panic attacks are not typical of serotonin syndrome. Hypomania relates to mood disorders, and arrhythmias are less common than tachycardia. Panic attacks are distinct, making this choice incorrect compared to the neurological and autonomic symptoms of serotonin syndrome.
