Answer to Question 1
Correct Answer: 1
Rationale 1: Ethambutol affects the ability to distinguish red from green.
Rationale 2: White patches are associated with fungal infections, not with ethambutol.

Rationale 4: Alteration in smelling does not occur with ethambutol.
Global Rationale: Ethambutol has a unique adverse effect of optic neuritis that affects visual acuity and the ability to distinguish red from green. This effect is dose related, may be unilateral or bilateral, and is usually reversible when therapy is discontinued. White patches, ringing in the ears, and alteration in ability to smell do not occur.

Global Rationale: In regions where the incidence of isoniazid resistance is 4 or higher, ethambutol (Myambutol) or streptomycin is included as part of the initial therapeutic regimen. Three months of additional therapy may be indicated, depending on whether the sputum cultures have turned negative during therapy. The remaining medications do not have this indication.
