Answer to Question 1

D
Feedback:
Histamine-2 antagonists are administered to reduce the amount of hydrochloric acid secreted in the stomach, which helps to prevent peptic ulcer disease. H2 antagonists do not act as an antibiotic to kill bacteria (i.e., H. pylori) coat and protect the stomach lining like sucralfate (Carafate), or increase the pH of the secreted hydrochloric acid.

Answer to Question 2

C
Feedback:
The onset of intramuscular lidocaine is 5 to 10 minutes, peaks within 5 to 15 minutes, and the duration of action is 2 hours. Options A, B, and D are distracters.
