A nurse is reinforcing teaching for a client who has a duodenal ulcer and a new prescription for sucralfate. The client asks the nurse how sucralfate works. Which of the following statements should the nurse make?
A.
“This medication adheres to the ulcer and protects it from gastric acid”
B.
“This medication neutralizes gastric acid after it is secreted”
C.
This medication kills the bacteria which cause ulcers
D.
“This medication prevents gastric acid secretion in the stomach”
The Correct Answer and Explanation is:
The correct answer is:
A. “This medication adheres to the ulcer and protects it from gastric acid.”
Explanation:
Sucralfate is a medication primarily used to treat and manage duodenal ulcers. Its main mechanism of action is unique among ulcer medications. Sucralfate is a sulfated polysaccharide that forms a sticky, viscous gel when it comes into contact with the acidic environment of the stomach. This gel adheres to the surface of the ulcer and creates a protective barrier. By binding to the ulcer, sucralfate shields it from gastric acid, pepsin, and bile salts, which helps to prevent further irritation and promotes healing.
Here’s a breakdown of why the other options are incorrect:
- B. “This medication neutralizes gastric acid after it is secreted”: This statement describes the action of antacids, not sucralfate. Antacids work by neutralizing stomach acid directly, which can help alleviate symptoms of heartburn and acid indigestion but do not provide a protective barrier over ulcers.
- C. “This medication kills the bacteria which cause ulcers”: This option describes the action of antibiotics, particularly those used to treat Helicobacter pylori (H. pylori) infection. H. pylori is a bacterium that can contribute to ulcer formation, and antibiotics are prescribed to eradicate it. Sucralfate does not have antibiotic properties and does not target bacteria.
- D. “This medication prevents gastric acid secretion in the stomach”: This describes the action of proton pump inhibitors (PPIs) or H2-receptor antagonists. PPIs and H2-blockers work by reducing the production of stomach acid, which helps in managing acid-related conditions but does not specifically protect the ulcer directly like sucralfate does.
Sucralfate is thus valuable in ulcer management due to its protective mechanism. By adhering to the ulcer and providing a physical barrier, it creates a more favorable environment for the ulcer to heal and minimizes irritation from gastric acids. This approach complements other treatments that may involve reducing acid production or addressing infection.
