The nurse is providing care to a client diagnosed with schizophrenia and is experiencing anticholinergic side effects from long-term use of typical antipsychotics. Which of the following symptoms would the nurse expect to see during an assessment?

Choice A reason: Akinesia, dystonia, and pseudoparkinsonism are extrapyramidal symptoms caused by dopamine receptor blockade in the nigrostriatal pathway from typical antipsychotics. These motor-related side effects differ from anticholinergic effects, which involve muscarinic receptor blockade affecting the parasympathetic system. The client’s symptoms do not align with these movement disorders. Choice B reason: Hyperglycemia and diabetes are metabolic side effects associated with atypical antipsychotics, not typical ones, due to effects on insulin regulation. Anticholinergic side effects from typical antipsychotics involve muscarinic receptor blockade, not metabolic pathways, making this an incorrect choice for the expected symptoms in this scenario. Choice C reason: Typical antipsychotics, like haloperidol, block muscarinic receptors, causing anticholinergic side effects such as dry mouth (reduced salivation), constipation (decreased gastrointestinal motility), and urinary retention (impaired bladder contraction). These symptoms result from parasympathetic inhibition, precisely matching the expected side effect profile for long-term use of these medications. Choice D reason: Muscle rigidity, hyperpyrexia, and tachycardia are symptoms of neuroleptic malignant syndrome, a rare, life-threatening reaction to antipsychotics, not routine anticholinergic side effects. This syndrome involves dopamine dysregulation and autonomic instability, distinct from the muscarinic receptor blockade causing anticholinergic effects, making it an incorrect choice.
