Answer to Question 1

ANS: A
Polyarthralgias occur in 40 of patients during the initial phase of treatment with pyrazinamide and can be managed with a nonsteroidal anti-inflammatory drug (NSAID). Renal function tests and uric acid levels are not indicated. Unless the pain cannot be managed with NSAIDs, there is no need to reduce the dose of pyrazinamide.

Answer to Question 2

ANS: A
Rifampin induces cytochrome P450 enzymes and can accelerate the metabolism of many drugs, including oral contraceptive pills (OCPs). Women taking OCPs should consider a nonhormonal form of birth control. Reducing the dose of rifampin or isoniazid is not indicated. Increasing the OCP dose is not recommended.
