Answer to Question 1

A
Feedback:
Some drugs are synergistic, which means that they are more powerful when given in combination. The health care provider may be encouraged to use a smaller dosage of each drug, leading to fewer adverse effects, but still having a therapeutic impact on the pathogen. Many microbial infections are caused by more than one organism; each pathogen may react to a different anti-infective agent. Combination drugs do not have a better chance at killing the microorganism and they do not increase the absorption of the drugs.

Answer to Question 2

A, B, C, D
Feedback:
Antacids neutralize stomach acid by direct chemical reaction. They are recommended for the symptomatic relief of upset stomach associated with hyperacidity, as well as the hyperacidity associated with peptic ulcer, gastritis, peptic esophagitis, gastric hyperacidity, and hiatal hernia. Duodenal ulcer is not an indication for the use of an antacid.
