When monitoring a client taking benztropine mesylate, the nurse should focus on which aspect?

When monitoring a client taking benztropine mesylate, it's essential to focus on the voiding pattern. Benztropine is an anticholinergic medication commonly used in the treatment of Parkinson's disease and to manage extrapyramidal symptoms caused by antipsychotic medications. One of the notable side effects of anticholinergic drugs like benztropine is urinary retention, which can lead to difficulty in urination or an altered voiding pattern.

Close observation of the patient's urinary habits helps identify any potential complications early on, such as urinary hesitancy or abnormal frequency, which can impact the patient’s comfort and overall health. Early detection of urinary retention allows for timely intervention, which is critical in preventing further complications.

While monitoring respiratory rate, heart rate, and visual changes can also be relevant in certain contexts, they are not the primary focus when it comes to the specific side effects associated with benztropine mesylate. The primary concern for a nurse would be to ensure that any issues with urinary function are promptly addressed, making it vital to monitor the voiding pattern closely.
