The nurse is caring for a client receiving ciprofloxacin (Cipro) for treatment of a urinary tract infection (UTI). The nurse will include which black box warning (BBW) in the discharge education?

The correct answer is A: This drug has a black box warning for causing tendon rupture. Ciprofloxacin belongs to the fluoroquinolone class of antibiotics, which carries a black box warning for tendon rupture, especially in older adults. Tendon rupture can occur within hours to weeks of starting the medication. This warning is crucial for patient safety as it can lead to severe complications. Thrombocytopenia (B), thromboembolic events (C), and endometrial cancers (D) are not associated with ciprofloxacin and are not part of its black box warning. Therefore, choices B, C, and D are incorrect. It is essential for the nurse to educate the client about the specific black box warning related to the medication they are receiving to ensure safe and effective treatment.
