A patient diagnosed with tuberculosis is prescribed ethambutol (EMB). Prior to initiating this medication, what should the nurse instruct the patient?
1. Avoid this medication if allergic to eggs.
2. Have a baseline visual exam.
3. Have an influenza (flu) vaccination.
4. Have a baseline ECG (electrocardiogram).
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.
