A patient develops a superinfection due to fluoroquinolone therapy. The patient asks the nurse why this happened. Which response by the nurse would be most appropriate?
- A. Your infection was really severe, so the drug wasn't as effective as it could have been.
- B. This happens when your original infection begins to clear.
- C. The drug disrupts your normal bacteria so it allows other organisms to grow.
- D. We really don't know why this happens; it just does sometimes.
Correct Answer: C
Rationale: Antibiotics can disrupt the normal flora (nonpathogenic bacteria in the bowel), causing a secondary infection or superinfection. This new infection is 'superimposed' on the original infection. The destruction of large numbers of nonpathogenic bacteria (normal flora) by the antibiotic alters the chemical environment. This allows uncontrolled growth of bacteria or fungal microorganisms that are not affected by the antibiotic being administered. It has nothing to do with the drug's effectiveness or the original infection being cleared.

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.
A client is receiving a fluoroquinolone as an extended-release formulation. Which of the following would be most important to include in the client's teaching plan?
- A. To chew, crush, or break the medication
- B. To swallow the medication whole
- C. To limit the daily fluid intake
- D. To take the drug with an antacid
Correct Answer: B
Rationale: When an extended-release formulation is prescribed, the client needs instructions to swallow the medication whole and not to chew, crush, or break the medication. Otherwise, the amount of drug released would be too great for the body all at once Clients should be encouraged to increase their fluid intake and to separate administration by 1 to 2 hours.
