Question

a nurse is discussing the use of calcium carbonate with a client who has frequent heartburn. which of the following effects of calcium carbonate should the nurse reinforce in the teaching? calcium carbonate will inhibit the secretion of gastric acid. calcium carbonate will block the hydrogen potassium atpase. calcium carbonate neutralizes gastric acid. calcium carbonate will form a protective barrier over ulcers.

Explanation:

Calcium carbonate is an antacid. Antacids work by neutralizing existing gastric acid, which relieves heartburn. Inhibiting gastric acid secretion is the action of proton pump inhibitors or H2 blockers, not antacids. Blocking hydrogen potassium ATPase is the mechanism of proton pump inhibitors. Forming a protective barrier is the action of medications like sucralfate.

Answer:

Calcium carbonate neutralizes gastric acid.
