The nurse is planning to administer an antacid to a patient diagnosed with PUD who will receive an H2 antagonist at 8:00 AM. When is the most appropriate time for the nurse to provide the antacid to this patient?

2 hours after the H2 antagonist

Within an hour after the H2 antagonist

With the H2 antagonist

30 minutes prior to the H2 antagonist

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is D

Explanation

A. Lubricates the intestinal wall and softens stool: This describes the action of lubricant laxatives, such as mineral oil, not stimulant laxatives.

B. Draws water into the bowel to facilitate the passage of feces: This describes osmotic laxatives, such as polyethylene glycol or lactulose.

C. Increases bulk and stimulates peristalsis: This describes bulk-forming laxatives, like psyllium, which absorb water and increase stool size.

D. Irritates the intestine directly, promoting peristalsis and evacuation: This is the correct mechanism for stimulant laxatives, such as bisacodyl and senna. They stimulate the nerve endings in the intestinal lining, leading to increased bowel movement activity.

A. Heartburn B. Nausea C. Anorexia D. Vomiting
