Answer to Question 1

ANS: D
Gemfibrozil is highly protein-bound and competes for receptor sites with drugs such as warfarin. The anticoagulant dose should be decreased, and the INR should be closely monitored. Decreasing the dose of gemfibrozil is not recommended. Giving the warfarin at a different time of day does not change this drug interaction. The warfarin dose should be decreased not increased.

Answer to Question 2

ANS: B
Patients taking statins should report immediately any muscle aches or weakness, which can lead to rhabdomyolysis, a muscle disintegration that can become fatal. All statins carry this risk, so changing to another statin is not indicated. Ibuprofen may be useful, but notifying the provider is essential. Patients should not abruptly discontinue statins without discussing this with the provider.
