The nurse is caring for a patient who has a peptic ulcer. To treat the ulcer and prevent more ulcers from forming, the nurse should be prepared to administer:
a. H2-histamine receptor blockers.
b. gastrin.
c. vagal stimulation.
d. vitamin B12.
A
Stimulants of hydrochloric acid secretion include vagal stimulation, gastrin, and the chemical properties of chyme. Histamine, which stimulates the release of gastrin, also stimulates the secretion of hydrochloric acid. Current drug therapies for ulcer disease use H2-histamine receptor blockers that block the effects of histamine and therefore hydrochloric acid stimulation. Vitamin B12 is critical for the formation of red blood cells (RBCs), and a deficiency in this vitamin causes anemia but has no effect on ulcer formation. Gastrin is a hormone that stimulates acid. The vagus nerve helps digestion; however, vagal stimulation is not a treatment for peptic ulcer disease.
