A client receiving levofloxacin comes to the clinic for a follow-up visit. The client tells the nurse, 'I used sunscreen but it didn't help.' Which response by the nurse would be most helpful?

  • A. Be sure to wear long sleeves and a wide-brimmed hat in addition to using sunscreen.
  • B. I guess you didn't apply enough sunscreen to be effective.
  • C. Maybe we need to change your medication because this is unusual.
  • D. The sunscreen should have worked. Are you sure you actually did use it?
Correct Answer: A

Rationale: The fluoroquinolone drugs cause severe photosensitivity reactions. Clients may experience 'sunburn' reactions even when they use sunscreen or sunblock products. Caution clients to wear cover-up clothing with long sleeves and wide-brimmed hats when outside in addition to sunblock preparations. Remind them that sunscreen needs to be applied repeatedly throughout the day or when going into water. Clients should be aware that glare during hazy or cloudy days can cause skin reactions as readily as direct sunlight on a clear day. Telling the client that he didn't apply enough or questioning the client's actual use of sunscreen is inappropriate. There is no need to change the medication because the client's report is not unusual.
