Select the 3 client statements that indicate an understanding of the teaching.

A. "I can expect my contact lenses to turn red or orange.” Rifampin causes red-orange discoloration of body fluids, including tears, sweat, urine, and saliva. This effect is harmless but can stain soft contact lenses permanently, so clients should be advised to use glasses instead. B. “I should notify my provider if I start taking new over-the-counter or prescription medications.” Rifampin is a potent enzyme inducer that can alter the metabolism of many drugs, including oral contraceptives and anticoagulants. The provider should be informed of any new medications to avoid potential drug interactions and ensure therapeutic effectiveness. C. “I will need to have someone observe me when I take my medication.” Directly observed therapy (DOT) is recommended to ensure adherence to tuberculosis treatment. A healthcare provider or designated individual supervises medication intake to improve compliance and reduce the risk of drug resistance. D. “I will need to have a repeat Mantoux test in 4 weeks.” A repeat Mantoux test is unnecessary for diagnosing active tuberculosis, as this condition is confirmed through sputum cultures and chest X-ray findings. Mantoux testing is primarily used for screening latent TB infections. E. “I am no longer contagious.” Clients with active tuberculosis remain contagious until they complete at least two weeks of effective multidrug therapy and show clinical improvement. Until then, infection control measures such as respiratory isolation should be followed. F. “I will need to take my medications for a total of 6 weeks.” The standard treatment for active tuberculosis lasts at least six months, typically involving a four-drug regimen for the first two months, followed by two drugs for the remaining four months. A six-week course is insufficient for eradication. G. "I can continue my current alcohol intake." Alcohol should be avoided due to the hepatotoxic effects of isoniazid, rifampin, and pyrazinamide. Combining alcohol with these medications increases the risk of liver damage, requiring clients to abstain or limit intake.
