- A. Decrease the dose if adverse effects occur.
- B. Chew the tablets well before swallowing.

Correct Answer: C
Rationale: The nurse should instruct the client to take frequent sips of water or chew gum to avoid dryness of the mouth.

They should be swallowed whole. Taking the drug on an empty stomach may cause gastric upset. The drug should be taken with food.
