    Why do patients recieving anticoagulants have Warfarin and Heparin overlapping?

    • Becuase one drug makes the other work better

    • Becuase patients usually have medical conditions that require both drugs with are for two totally different medical conditions

    • Because the onset of Warfarin is 2-7 days

    Correct Answer
    A. Because the onset of Warfarin is 2-7 days
    Explanation
    Patients receiving anticoagulants often have Warfarin and Heparin overlapping because the onset of Warfarin is 2-7 days. Heparin is used initially to quickly achieve anticoagulation while waiting for Warfarin to take effect. Heparin acts rapidly, but its effect is short-lived, so it is often used in combination with Warfarin to provide continuous anticoagulation until Warfarin reaches its therapeutic level. This overlapping allows for a smooth transition and ensures that the patient remains adequately anticoagulated throughout the treatment process.
