- Do it
The Correct Answer and Explanation is:
Correct Answer: a) Coumadin
Explanation:
Mrs. King’s symptoms of bloody gums when brushing and bruising on her arms and legs are classic signs of bleeding tendencies. These are especially concerning when evaluating a patient’s medication regimen, as certain drugs can interfere with the body’s ability to form blood clots.
Coumadin (generic name: warfarin) is an anticoagulant, commonly referred to as a blood thinner. It is prescribed to prevent the formation of dangerous blood clots in conditions such as atrial fibrillation, deep vein thrombosis (DVT), pulmonary embolism (PE), or after certain surgeries. Coumadin works by inhibiting the synthesis of vitamin K-dependent clotting factors (factors II, VII, IX, and X), which are essential for normal blood clotting.
Because Coumadin reduces the body’s ability to clot blood, patients are at increased risk for bleeding, even with minor injuries. Common signs of excessive anticoagulation or bleeding include:
- Bleeding gums, especially when brushing
- Easy bruising or unexplained bruises
- Blood in the urine or stool
- Nosebleeds
- Prolonged bleeding from cuts
Mrs. King’s symptoms are consistent with these side effects, making Coumadin the most likely drug of concern. This situation should be immediately reported to the healthcare provider, as it may indicate that her INR (International Normalized Ratio) level is too high, putting her at increased risk for serious or even life-threatening bleeding. The provider may need to adjust the dose or temporarily discontinue the medication.
Option b: Lasix (furosemide) is a diuretic used to reduce fluid retention. While it may cause electrolyte imbalances, it does not commonly cause bleeding or bruising.
Option c: Insulin is used to manage blood sugar levels in diabetes. Though hypoglycemia is a concern, bleeding is not a typical side effect.
Conclusion: Coumadin is the drug most associated with Mrs. King’s bleeding symptoms and warrants immediate attention.
