A Patient Is Taking Azithromycin (Zithromax)-Doxycycline Prescribed by His Physician

A patient is taking azithromycin (Zithromax) -doxycycline prescribed by his physician for acute bronchitis.He tells the nurse that the information provided by his pharmacy indicates that this drug causes photosensitivity,and he asks about what will happen to him if he is exposed to sunlight while taking the drug.What is the nurse's best response?

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