A nurse is monitoring a client who is receiving haloperidol. Which of the following findings is the priority to report to the provider?

Choice A reason: Hypoactive bowel sounds can indicate a variety of gastrointestinal issues, but they are not typically associated with haloperidol use. While it is important to monitor bowel sounds, it is not the priority in this context. Choice B reason: Dry mouth is a common side effect of many medications, including haloperidol. While it can be uncomfortable for the client, it is not usually a serious concern and can be managed with hydration and other supportive measures. Choice C reason: Constant opening and closing of the mouth, also known as tardive dyskinesia, is a serious side effect of haloperidol and other antipsychotic medications. This condition involves involuntary muscle movements and can be irreversible. It is crucial to report this finding to the provider immediately for assessment and potential adjustment of the medication regimen. Choice D reason: Photosensitivity is not a common side effect of haloperidol. While it is important to monitor for any new or unusual symptoms, photosensitivity is not typically associated with this medication.
