A nurse is teaching a client who has a duodenal ulcer about his new prescription for cimetidine. The nurse should include which of the following instructions in the teaching?
“Take the medication on an empty stomach for better absorption”
"You should plan to take this medication for at least 6 months."
"Your doctor might need to reduce your theophylline dose While taking this medication."
"Take the medication with an antacid to minimize stomach upset."
The Correct Answer is C

A-Cimetidine should be taken with meals or at bedtime for more effective absorption and optimal therapeutic effect.
B. There is no specific duration mentioned for the treatment of duodenal ulcer with cimetidine.
D. Taking cimetidine with an antacid is not recommended as they decrease the absorption of cimetidine.
