Correct Answer is A

Explanation

A. 2 hours after the H2 antagonist: Antacids should be administered at least 1 to 2 hours after H2 antagonists to avoid reducing the effectiveness of the H2 antagonist. H2 antagonists work by reducing stomach acid, and antacids neutralize it, so taking them too close together may reduce the effectiveness of both.

B. Within an hour after the H2 antagonist: This is incorrect because taking an antacid too soon after an H2 antagonist can interfere with the drug's action.

C. With the H2 antagonist: This is incorrect because administering antacids with an H2 antagonist could reduce the effectiveness of both medications.

D. 30 minutes prior to the H2 antagonist: This is incorrect because antacids should not be given before the H2 antagonist, as it may decrease the medication's effectiveness.

A. 1 hour after meals B. 1 hour before meals C. With meals D. With a bedtime snack

Correct Answer is B

Explanation

A. 1 hour after meals: Sucralfate works by forming a protective barrier over ulcers. It is best absorbed when the stomach is empty, so taking it after meals reduces its effectiveness.

B. 1 hour before meals: Sucralfate should be administered 1 hour before meals to allow it to form a protective barrier in the stomach lining without interference from food.

C. With meals: Taking sucralfate with meals can interfere with its ability to coat the stomach effectively.

D. With a bedtime snack: Sucralfate should be taken on an empty stomach for optimal effectiveness, not with food.
