A condition in which a blood clot forms most often in the deep veins of the leg is known as Venous thromboembolism (VTE. This causes pain for the patient and can be corrected through different ways. Below is a pharmacotherapy test on Venous Thromboembolism. Give it a shot and get to refresh your memory on all that we have learnt do far.

Monitor Hgb, Hct, and BP. Lower the dose of UFH. Administer IV protamine sulfate.

Monitor Hgb, Hct, and BP. Discontinue UFH. Administer IV Vitamin K and fresh frozen plasma.
Not UFH, because it is not safe during breastfeeding.
Not UFH, because there is a risk of maternal hemorrhage.
LMWH is a better alternative because it does not cross the placenta.
These drugs cross the placenta.
