Answer to Question 1

Correct Answer: 2
Before starting on ethambutol (EMB), a baseline visual examination is indicated. Eye exams also may be scheduled during the course of treatment. This medication can cause optic neuritis. An allergy to eggs or administration of a flu vaccine or an ECG is not warranted prior to the implementation of this medication.

Answer to Question 2

Correct Answer: 1
INH should be taken one hour before meals or on an empty stomach, since food interferes with the absorption of the drug. To avoid drug interactions, patients should advise all healthcare providers that they are taking the medication. The patient should avoid alcohol because of the harmful effects to the liver while taking this medication. Because of the risk of hepatotoxicity, the patient should have baseline and monthly evaluations of liver function while on INH.
