A patient diagnosed with benign prostatic hyperplasia (bph) is on tamsulosin therapy. on the follow-up visit, the nurse finds that the patient has an increased clotting time. which medication in the patient's medical history does the nurse expect to be the cause of this condition? insulin nadolol warfarin epinephrine

In this case, the full medical history of the patient is not endorsed. A patient undergoing treatment of benign prostatic hyperplasia with tamsulosin, an alpha receptor antagonist, will not usually present with deranged clotting mechanisms. From the choices, only warfarin; which actions to antagonize the action of vitamin K thereby significantly reduce vitamin K dependent clotting factors such as factor II, factor VII, factor IX, and factor X. In reducing the levels of vitamin K dependent clotting factors, clotting time; both intrinsic (prothrombin time) and extrinsic (activated thromboplastin time) pathways will be deranged.
