Answer to Question 1

B
Feedback:
The histamine2 receptor antagonists (H2RAs) inhibit both basal secretion of gastric acid and the secretion stimulated by histamine, acetylcholine, and gastrin. These drugs, such as ranitidine, do not change the pH of secretions, bind to the proton pumps, or decrease gastric motility.

Answer to Question 2

D
Feedback:
The recommended dietary allowance, or RDA, for vitamin D is 600 International Units for people 1 to 70 years of age and 800 International Units daily for adults 71 years and older to prevent and treat osteoporosis.
