Chapter 50 : Acid-Controlling Drugs Questions
Question 1 of 5
The nurse is providing patient teaching about antacids. Which statements about antacids are accurate? (Select all that apply.)
Correct Answer: B,C,E
Rationale: Antacids neutralize acid in the stomach. Magnesium-based antacids cause diarrhea, and aluminum-based antacids cause constipation. Calcium-based antacids often cause rebound hyperacidity.
Question 2 of 5
A patient will be receiving pantoprazole, 20 mg IV daily every morning. The medication, once reconstituted, has a strength of 40 mg/10 mL. Identify how many milliliters the nurse will draw up for this dose.
Correct Answer: 5 mL
Rationale: Calculate dose: 40 mg:10 mL::20 mg:x mL. (40 ?? x) = (10 ?? 20); 40x = 200; x = 5 mL.
Question 3 of 5
A patient is receiving an aluminum-containing antacid. The nurse will inform the patient to watch for which possible adverse effect?
Correct Answer: B
Rationale: Aluminum-based antacids have a constipating effect as well as an acid-neutralizing capacity.
Question 4 of 5
When reviewing the health history of a patient who will be receiving antacids, the nurse recalls that antacids containing magnesium need to be used cautiously in patients with which condition?
Correct Answer: B
Rationale: Both calcium- and magnesium-based antacids are more likely to accumulate to toxic levels in patients with renal disease and are commonly avoided in this patient group.
Question 5 of 5
The nurse is reviewing the medication orders for a patient who will be taking an H2 antagonist. Which drug may have an interaction if taken along with the H2 antagonist?
Correct Answer: D
Rationale: All H2 receptor antagonists may inhibit the absorption of certain drugs, such as the antifungal ketoconazole, that require an acidic gastrointestinal environment for gastric absorption.
