Nursing Knowledge: The nursing assessment of a patient indicates positive signs for Neuroleptic Malignant Syndrome (NMS). Select all that apply.

Choice A reason: NMS occurs in patients taking antipsychotics, particularly dopamine antagonists. Low suspicion of anyone on antipsychotics is incorrect because NMS is directly linked to antipsychotic use. Choice B reason: Neurological symptoms such as tremors, delirium, agitation, and seizures are hallmark signs of NMS. These reflect dopamine blockade and autonomic instability. Choice C reason: Muscular rigidity, autonomic instability (hypotension or hypertension), and tachycardia are classic features of NMS. These symptoms are critical for diagnosis and require immediate intervention. Choice D reason: NMS is associated with elevated creatine phosphokinase (CPK) due to muscle breakdown and leukocytosis from systemic stress. Low levels would not be consistent with NMS.
