Answer to Question 1

ANS: A
The high heparin doses used in cardiac bypass surgery can be monitored using the PTT.

Answer to Question 2

ANS: D
Normal platelet aggregation requires fibrinogen. Ristocetin is a substance added in vitro that causes platelet to clump. VWF is needed for normal platelet adhesion. Epinephrine is a platelet agonist stimulating platelet aggregation, but it is not necessary.
