The nurse caring for a patient who has tuberculosis and who is taking isoniazid, rifampin, and streptomycin reviews the medical record and notes the patient's sputum cultures reveal resistance to streptomycin. The nurse will anticipate that the provider will take which action?
- A. Add ethambutol (Myambutol)
- B. Change the streptomycin to clarithromycin
- C. Change the streptomycin to kanamycin
- D. Order renal function tests
Correct Answer: C
Rationale: Kanamycin replaces streptomycin in phase I resistance; ethambutol is for INH resistance, and clarithromycin is phase II. The patient's current regimen is first-phase treatment. If resistance to streptomycin develops, the provider can change to kanamycin or to ciprofloxacin.

Rationale: It is important to follow package directions because OTCs are medications that can cause serious harm if not taken properly.

They may have originally been prescription drugs that were tested by the FDA or they may have been grandfathered in when the FDA laws changed. OTC education should always be included as a part of the hospital discharge instructions.
