A nurse is planning care for a client who is taking benztropine to reduce extrapyramidal manifestations developed secondary to taking an antipsychotic medication. For which of the following adverse effects of benztropine should the nurse monitor?

Choice A reason: Benztropine has anticholinergic properties, which decrease sweating rather than increase it. Clients are at risk for heat intolerance and hyperthermia, not diaphoresis. Choice B reason: Tachycardia is a common anticholinergic adverse effect due to vagal inhibition and increased heart rate. Monitoring cardiovascular status is essential, especially in older adults or those with cardiac disease. Choice C reason: Anticholinergic medications reduce gastrointestinal motility, leading to constipation rather than diarrhea. Therefore, diarrhea is not expected. Choice D reason: Benztropine causes urinary retention, not polyuria. Clients may have difficulty initiating urination or experience bladder distention.
