A nurse is preparing to educate a patient who has newly been prescribed sucralfate (Carafate) for the management of peptic ulcer disease (PUD). What is the mechanism of action for this medication?
Neutralizes the acidity of the gastric acid.
Acts as an endogenous prostaglandin in the GI tract.
Antagonizes H2 receptors on parietal cells.
Creates a protective barrier that adheres to an ulcer, which can stick to the ulcer for up to 6 hours.
The Correct Answer is D
A. Sucralfate does not neutralize gastric acid; antacids are responsible for neutralization.
B. Sucralfate does not mimic endogenous prostaglandins. Medications like misoprostol act as prostaglandins to protect the stomach lining.
C. Sucralfate does not block H2 receptors. Medications like cimetidine or ranitidine work through this mechanism to reduce acid production.
D. Sucralfate creates a viscous, protective barrier that adheres to the ulcer site, shielding it from further damage by gastric acid, bile, and pepsin for up to 6 hours, thereby promoting healing.

Explanation
A. Glucagon is not used to treat thyroid cancer; treatments for thyroid cancer often include radioactive iodine therapy or surgery.
B. Glucagon is used to treat severe hypoglycemia in diabetic patients when they are unable to take oral glucose. It works by stimulating the liver to release stored glucose into the bloodstream, rapidly raising blood sugar levels.
C. Diabetes insipidus involves a deficiency of antidiuretic hormone or kidney insensitivity to it and is treated with desmopressin or adequate hydration, not glucagon.
D. Type 2 diabetes mellitus is typically managed with lifestyle changes, oral antidiabetic agents, or insulin. Glucagon is not used for routine management but is reserved for severe hypoglycemia emergencies.
Correct Answer is ["B","D"]
Explanation
A. Restlessness is not a common side effect of cimetidine. Neurological side effects typically involve sedation or confusion rather than hyperactivity.
B. Lethargy is a potential adverse effect of cimetidine, especially in older adults or those with renal dysfunction, due to the drug’s impact on the central nervous system.
C. Increased libido is not associated with cimetidine. In fact, it may cause decreased libido and sexual dysfunction in some cases.
D. Confusion is a known complication of cimetidine, particularly in elderly clients with impaired renal function, as the drug can accumulate in the body and affect the brain.
