Study Notes
Question 1
- Pyridoxine (vitamin B6) is often co-prescribed with isoniazid (INH) to prevent peripheral neuropathy.
- Hepatitis, optic neuritis, and skin rashes are not prevented by vitamin B6.
Question 2
- Rifampin therapy for tuberculosis can cause red-orange discoloration of urine and tears.
- Patients should not use contact lenses while taking rifampin.
- Patients should take the medication exactly as prescribed, to prevent resistance.
- Patients should report any unusual symptoms to their healthcare provider.
Question 3
- Patients on ethambutol therapy may experience difficulty distinguishing between red and green colors.
- Notify the healthcare provider for further evaluation.
- Ethambutol can cause optic neuritis, which may present as difficulty distinguishing colors or decreased visual acuity.
Question 4
- Hepatotoxicity is a primary adverse effect of pyrazinamide, which is monitored by liver function tests.
- Red-orange discoloration of body fluids is an adverse effect of rifampin.
- Peripheral neuropathy is an adverse effect of isoniazid.
- Optic neuritis is an adverse effect of ethambutol.
Question 5
- Rifater (combination therapy) is used to prevent drug resistance in tuberculosis.
- Combination therapies for tuberculosis can minimize therapy duration, improve patient compliance, and reduce side effects.
Question 6
- Tingling and numbness in hands and feet are symptoms of peripheral neuropathy.
- Administer pyridoxine (vitamin B6) as prescribed.
Question 7
- Patients should report any changes in vision to their healthcare provider when taking ethambutol.
- Ethambutol can cause optic neuritis.
- Red-orange discoloration is a side effect of rifampin.
- Tingling is a possible side effect of isoniazid.
Question 8
- Combination therapy helps prevent the development of drug resistance in tuberculosis.
- Rifampin can be effective on its own, but resistance develops quickly when not used with other drugs.
Question 9
- Assess liver function tests as a priority if a patient taking pyrazinamide reports nausea or mild upper abdominal pain.
- Monitoring liver function tests identifies potential liver damage (hepatotoxicity).
Question 10
- Conduct visual acuity and color perception tests before and during treatment to detect potential problems.
- Ethambutol can cause optic neuritis, which may result in vision changes, including decreased acuity and color blindness.
Question 11
- Rifater contains rifampin, pyrazinamide, and isoniazid.
Question 12
- Adherence is important to avoid the development of multidrug-resistant tuberculosis.
- Multiple medications are used to ensure more effective treatment.
