A client is receiving a fluoroquinolone and is also taking ibuprofen for pain relief. The nurse would be alert for which of the following?
- A. Increased risk for bleeding
- B. Decreased effectiveness of the fluoroquinolone
- C. Increased risk for seizures
- D. Delayed elimination of the fluoroquinolone
Correct Answer: C
Rationale: When a nonsteroidal anti-inflammatory drug such as ibuprofen is used in conjunction with a fluoroquinolone, the patient has an increased risk for seizures. An increased risk of bleeding would occur with oral anticoagulants in conjunction with fluoroquinolone therapy. Decreased effectiveness of the fluoroquinolone would occur if it was given with antacids, iron salts, or zinc because of decreased absorption of the antibiotic. Cimetidine interferes with the elimination of the fluoroquinolone, leading to prolonged presence of the drug in the bloodstream.
