Acid Reducing Meds Pharmacology #4

Question

Which statement by the nursing student should be corrected by the nursing instructor?

Answers

  1. “Antacids and cimetidine can be administered at the same time to patients.”
    • Rationale:

      This answer is correct because antacids should be given at least one hour apart from most medications, including cimetidine. Antacids decrease absorption of many medications, which could cause significant consequences to the patient. This should be taught if antacids are taken by the patient.

  2. “Famotidine and ranitidine do not have to be administered with food.”
    • Rationale:

      This answer is not correct because famotidine and ranitidine do not have to be taken with food. Absorption of these medications is not affected by food, but antacids decrease absorption of these and other medications. Patients should be educated regarding this.

  3. “Ranitidine is a histamine (H2) receptor antagonist used to suppress gastric acid.”
    • Rationale:

      This answer is not correct because ranitidine is a histamine (H2) receptor antagonist used to suppress gastric acid. This class of medication is effectively used as treatment of gastroesophageal reflux disease (GERD) and peptic ulcers.

  4. “The dosage of cimetidine should be reduced in patients with renal impairment.”
    • Rationale:

      This answer is not correct because the dosage of cimetidine should be reduced in patients with renal impairment. Cimetidine competes for renal tubular handling, which can affect renal function.

Overview

Histamine (H2) receptor antagonists should be given at least 1 hour apart from antacids. Antacids can decrease absorption of many medications, including cimetidine.

Explanation

Learning Outcomes

Antacids should be given at least one hour apart from most medications. Antacids can decrease absorption of many medications. Medication actions are often significantly affected if antacids are given at the same time as other drugs. This could be very dangerous or life threatening, depending on the medication. This should be taught if antacids are taken by the patient.

Test Taking Tip

Focus your study time on the common health problems that nurses most frequently encounter.
