Answer to Question 1

ANS: C
The PTT (or sometimes factor anti-Xa) is used to monitor heparin therapy for therapeutic benefit. The platelet count is also monitored to detect thrombocytopenia, a side effect of heparin. The PT is used to monitor warfarin (Coumadin) therapy. The RBC count is not used to determine anticoagulation benefit.

Answer to Question 2

ANS: D
Plasmapheresis is used to remove plasma containing harmful substances such as cholesterol, antigen-antibody complexes, and toxins. Erythrocytaphoresis removes red blood cells. Leukapheresis removes white blood cells. Apheresis is a generic term that encompasses all types of these procedures.
