Question

When coumadin therapy is therapeutic, the International Normalized Ratio (INR) should ideally be between:

a) 1.5 and 2.5
b) 2 and 3
c) 3 and 4
d) 4 and 5

Answer 1

The ideal therapeutic International Normalized Ratio (INR) range for coumadin therapy is typically between 2 and 3 for most indications, although certain conditions may require a different range.

Step-by-step explanation:

When undergoing coumadin therapy, which is a form of anticoagulant medication to prevent blood clots, the International Normalized Ratio (INR) is used as a standard measure to ensure the treatment is effective without increasing the risk of bleeding. The optimal therapeutic range of INR for most indications falls between 2 and 3. Therefore, the correct answer to the question 'When coumadin therapy is therapeutic, the International Normalized Ratio (INR) should ideally be between:' is b) 2 and 3. However, there are certain conditions that might require a slightly higher INR range, such as mechanical heart valves, which might call for an INR between 2.5 and 3.5 or higher based on individual risk factors and physician recommendations.
