5 Questions
How is the International Normalized Ratio (INR) used in the context of anticoagulation therapy?
To measure blood coagulation and determine the clotting rate affected by liver damage and Vitamin K levels.
What is the primary mechanism by which antibiotic medications interact with warfarin to increase the risk of major bleeding?
Disruption of intestinal flora that synthesize Vitamin K.
What is the preferred range of INR levels for a patient on anticoagulation therapy?
Between 2 and 3
Which factor does the dose of warfarin aim to maintain within a target range?
Clotting time
In what way does the International Normalized Ratio (INR) differ from prothrombin time?
INR is a derivative of prothrombin time, both measuring blood coagulation, affected by anticoagulant usage, liver damage, and Vitamin K levels.
