81. Which of the following is a potential adverse effect of warfarin?
Answer: B
Bleeding
Warfarin is an anticoagulant medication that works by inhibiting blood clot formation, which can lead to an increased risk of bleeding as a potential adverse effect.
A) Hypoglycemia
Hypoglycemia is a condition characterized by abnormally low blood glucose levels and is not a known adverse effect of warfarin. Warfarin primarily affects blood coagulation and does not influence blood sugar levels directly.
B) Bleeding
Bleeding is a significant and well-documented adverse effect of warfarin. Due to its anticoagulant properties, warfarin increases the risk of both minor and major bleeding events, making this option the correct answer.
C) Hypertension
Hypertension, or high blood pressure, is not a direct adverse effect of warfarin. While blood pressure can be influenced by various factors, warfarin’s mechanism does not typically cause an increase in blood pressure levels.
D) Tachycardia
Tachycardia refers to an increased heart rate and is not a recognized adverse effect of warfarin. Warfarin's primary role is to prevent clotting rather than to directly impact heart rate.
Conclusion
Bleeding is the correct answer as it directly relates to the anticoagulant effects of warfarin, which can lead to serious complications if not monitored properly. The other options—hypoglycemia, hypertension, and tachycardia—are not associated with warfarin use, confirming that they do not pose the same risk as bleeding.
