Final answer:
The INR of 5.2 for a client prescribed warfarin is considered supratherapeutic, which is higher than the normal therapeutic range of 2.0 to 3.0 (or up to 3.5 for some conditions) and indicates an increased risk of bleeding.
Step-by-step explanation:
If a client is prescribed warfarin and their International Normalized Ratio (INR) is 5.2, this indicates that the dose is supratherapeutic. Typically, the therapeutic range for INR is between 2.0 and 3.0 for most conditions requiring warfarin. However, some conditions may require a slightly higher target INR range, up to 3.5. An INR of 5.2 is higher than the usual therapeutic range, which can increase the client's risk of bleeding. It is essential for healthcare providers to monitor INR levels regularly and adjust the warfarin dose accordingly to maintain it within the therapeutic range. If the INR is too high, the dose of warfarin may need to be decreased, or vitamin K or other treatments may be administered to reverse the effects of warfarin and reduce the risk of bleeding.
