Answer to Question 1

D
Ofloxacin increases plasma levels of warfarin, so coagulation tests should be monitored. The of-loxacin dose should not be reduced or increased. Ofloxacin does not affect theophylline levels.

Answer to Question 2

D
Cationic compounds, including calcium supplements, can reduce the absorption of ciprofloxacin, so proper interval dosing is necessary. Consuming extra fluids is not indicated. With proper in-terval dosing, it is not necessary to discontinue the calcium while giving the ciprofloxacin. These two medications should not be given together.
