Final answer:
The therapeutic range for INR following a mechanical valve replacement is typically between 2.0 and 3.0.
Step-by-step explanation:
The therapeutic range for INR (International Normalized Ratio) following a mechanical valve replacement is typically between 2.0 and 3.0.
The INR measures the blood's ability to clot, and a mechanical valve replacement increases the risk of blood clotting in the body. Thus, maintaining the INR within the therapeutic range helps ensure appropriate blood clotting while minimizing the risk of excessive clotting.
Patients with a mechanical valve replacement need to regularly monitor their INR level and adjust their medication, such as warfarin, to keep it in the target range. This involves regular blood tests and close monitoring by healthcare professionals.
