Question

a nurse is providing teaching for a client who takes an oral contraceptive and is about to begin rifampin therapy to treat tuberculosis. which of the following instructions should the nurse include?

• increase the rifampin dose.
• increase the oral contraceptive dose.
• allow 2 hr between taking the two medications.
• use a non - hormonal form of contraception.

Explanation:

Rifampin is a liver enzyme inducer that significantly reduces the effectiveness of oral hormonal contraceptives, making them unreliable for pregnancy prevention. Increasing the rifampin dose, increasing the oral contraceptive dose, or spacing the medications does not adequately mitigate this interaction. The only reliable instruction is to switch to a non-hormonal contraceptive method.

Answer:

D. Use a non-hormonal form of contraception.
