Correct Answer is C

Explanation

A. Take the medication in the morning to prevent insomnia: This instruction is not directly

related to minimizing anticholinergic effects; it's more about managing the timing of medication administration.
B. Use cooling measures to decrease fever: Anticholinergic effects do not typically cause fever, so this instruction is not relevant.
C. Chew sugarless gum to moisten the mouth: Anticholinergic medications can cause dry mouth (xerostomia), and chewing gum can stimulate saliva production, alleviating this side effect.
D. Take an antacid to relieve nausea: Anticholinergic effects can include nausea, but taking an antacid is not a specific strategy for managing this side effect.

A. Do slow position changes to avoid falls from lowering blood pressure." B. if you feel short of breath, use a rescue inhaler. C. "If possible, try to avoid rooms that are cold." D. "Make sure to seek care immediately if you're not able to urinate."

Correct Answer is D

Explanation

A. Do slow position changes to avoid falls from lowering blood pressure: This is not the priority teaching point for an anticholinergic medication. While some anticholinergics can cause orthostatic hypotension, the risk of urinary retention is a more significant concern.
B. If you feel short of breath, use a rescue inhaler: This instruction is unrelated to the use of anticholinergic medication and may be more relevant for patients with emphysema.
C. "If possible, try to avoid rooms that are cold.": Avoiding cold rooms is not directly related to the use of anticholinergic medication. The priority teaching point should address potential adverse effects specific to the medication.
D. "Make sure to seek care immediately if you're not able to urinate.": Anticholinergic medications can exacerbate urinary retention, particularly in older adults with benign prostatic hyperplasia. It's crucial for the patient to understand the importance of seeking medical attention if they experience difficulty urinating.
