Answer to Question 1

D
Moxifloxacin prolongs the QT interval and poses a risk of serious dysrhythmias. Patients with hypokalemia have an increased risk, so serum electrolyte levels should be monitored. Having a history of asthma is not significant. Moxifloxacin does not alter digoxin or warfarin levels.

Answer to Question 2

A
C. difficile is resistant to fluoroquinolones; metronidazole is the drug of choice to treat this infec-tion. Metronidazole is lethal only to anaerobic organisms, so the ciprofloxacin should be contin-ued to treat the pneumonia. Increasing the dose of ciprofloxacin is not indicated, because C. dif-ficile is resistant to ciprofloxacin. Gemifloxacin is approved for use in respiratory infections.
