Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

b. The medication will inhibit development of gastric ulcers.
c. The medication will prevent irritation of the enlarged veins.
d. The medication will decrease nausea and improve the appetite.
Ans: c. The medication will prevent irritation of the enlarged veins.
Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acid gastric contents. Although ranitidine does decrease the risk for peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, these are not the primary purposes for H2-receptor blockade in this patient.
