A Patient Who Is Taking Azithromycin (Zithromax) Tells the Nurse

A patient who is taking azithromycin (Zithromax) tells the nurse that the information provided by the pharmacy indicates this drug causes photosensitivity. The patient asks what will happen with exposure to sunlight while taking the drug. The best response by the nurse is that

A) heat from the sun is readily absorbed by the body and may lead to problems with heat intolerance.
B) the most common effect of photosensitivity is corneal damage because the drug causes corneal absorption of UV light.
C) sun exposure may cause an exaggerated sunburn with redness, swelling, and blistering on exposed areas.
D) photosensitivity causes abnormal melanocyte activity on exposure to UV light, resulting in splotchy, abnormally dark tanning.
