Answer to Question 1

Ans: C
Feedback:
Combining warfarin with quinine increases the risk of bleeding. There is no risk of increased absorption or increased metabolism and no increased risk of heart attack associated with taking warfarin and quinine.

Answer to Question 2

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.
