A nurse is caring for a client who has schizophrenia and is taking haloperidol. The nurse should monitor for which of the following adverse effects of haloperidol?

Choice A reason: Extrapyramidal symptoms (EPS) are a common adverse effect of haloperidol, a first-generation antipsychotic. EPS includes symptoms such as tremors, rigidity, bradykinesia, and tardive dyskinesia. These symptoms result from the drug’s effect on the dopaminergic pathways in the brain. Choice B reason: Intractable hiccups are not a known adverse effect of haloperidol. This symptom is more commonly associated with other conditions or medications, but not with antipsychotic drugs like haloperidol. Choice C reason: Excessive salivation is not typically associated with haloperidol. Antipsychotic medications can cause dry mouth rather than excessive salivation. This symptom is more commonly seen with other medications or conditions. Choice D reason: Fever is not a common adverse effect of haloperidol. While fever can occur in the context of neuroleptic malignant syndrome (a rare but serious reaction to antipsychotics), it is not a typical side effect of haloperidol use. The primary concern with haloperidol is the development of extrapyramidal symptoms.
