Answer to Question 1

A
Feedback:
The antituberculosis drugs are always used in combination to affect the bacteria at various cellular stages and first-line drugs are always the first choice, using second-line drugs only when the patient is unable to take the first-line medications. Because this patient is pregnant, the safest choices would be isoniazid, ethambutol, and rifampin but no drug is administered during pregnancy unless the benefit outweighs the risk. The other drug choices would be less safe and would not be used unless the safer drugs were contraindicated.

Answer to Question 2

D
Feedback:
Locally acting antiemetics depress areas of the CNS. If combined with other CNS depressants, such as alcohol, patients could experience increasing CNS depression including dizziness and somnolence. St. John's wort, calcium channel blockers, and SSRIs are not CNS depressants.
