Question

What is the purpose of monitoring laboratory results for warfarin administration?

1) To assess the effectiveness of warfarin therapy
2) To evaluate the patient's risk of bleeding
3) To determine the appropriate dosage of warfarin
4) To monitor for drug interactions

Answer 1

Monitoring laboratory results for warfarin administration is important to assess effectiveness, evaluate bleeding risk, determine appropriate dosage, and monitor for drug interactions.

Step-by-step explanation:

The purpose of monitoring laboratory results for warfarin administration is to assess the effectiveness of warfarin therapy, evaluate the patient's risk of bleeding, determine the appropriate dosage of warfarin, and monitor for drug interactions.

1) To assess the effectiveness of warfarin therapy: By monitoring laboratory results such as the international normalized ratio (INR), healthcare providers can evaluate how well warfarin is working in preventing blood clots.

2) To evaluate the patient's risk of bleeding: Monitoring laboratory results can help identify if the patient is at an increased risk of bleeding due to warfarin therapy.

3) To determine the appropriate dosage of warfarin: Laboratory results can guide healthcare providers in adjusting the dosage of warfarin to achieve the desired therapeutic effect.

4) To monitor for drug interactions: Certain medications or substances can interact with warfarin and impact its effectiveness or increase the risk of bleeding. Monitoring laboratory results can help detect these interactions.
