  a. reduce the dose of ofloxacin.
  b. increase the dose of ofloxacin.
  c. increase the dose of theophylline.
  d. monitor coagulation levels.

Question 2

A provider orders intravenous moxifloxacin (Avelox) for a patient who has sinusitis. Before administering the drug, the nurse will review this patient's chart for:
 
  a. a history of asthma.
  b. concurrent use of digoxin.
  c. concurrent use of warfarin.
  d. recent serum electrolyte levels.

Answer to Question 1

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

Answer to Question 2

ANS: 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.
