A patient is receiving doxycycline as short-term therapy for malaria. Which of the following instructions would the nurse include in the teaching plan about the possible side effects of the drug?
A) Avoid taking warfarin because it increases the risk of bleeding.
B) Avoid exposure to the sun by wearing protective clothing.
C) Take the drug with food, or immediately afterward.
D) Do not drive or perform other activities requiring alertness.
Ans: B
Feedback:
The nurse should instruct the patient to avoid exposure to the sun by wearing protective clothing (e.g., long-sleeved shirts, wide-brimmed hats) and by using sunscreen. Combining warfarin with quinine, not doxycycline, increases the risk of bleeding. Doxycycline should be taken on an empty stomach. Doxycycline does not impair alertness, so the patient can drive or perform other activities requiring alertness.
