A patient with tuberculosis is taking rifampin, ethambutol, isoniazid, and pyrazinamide. The patient states that his contact lenses are stained orange after each use. How should the nurse respond?
Explanation
• Rifampin may cause body fluids to become red or orange. Urine, tears, sweat, sputum, and feces can all be affected. This is a benign side effect.
• Calling the physician is unnecessary, as this is an expected adverse reaction that is harmless.
• Incorrect: Administering a vitamin K injection is not indicated; there are no signs of bleeding.
• Incorrect: A patient should never discontinue tuberculosis medications without consulting a physician.
