A patient is prescribed benztropine for Parkinson's disease. The nurse should closely monitor which of the following to assess for a common side effect of benztropine?
• Benztropine is an anticholinergic medication and has typical anticholinergic side effects such as urinary retention, tachycardia, dry mouth, dry eyes, constipation, and blurred vision.
• The nurse should closely monitor the patient's intake and output while taking benztropine.
• Benztropine does not affect oxygen saturation, respirations, or hemoglobin. Benztropine can cause sedation, but it does not suppress the respiratory system.
