Answer to Question 1

B
PT measures the portion of the clotting cascade that is changed with oral anticoagulant treatment. PT could identify defects in the clotting cascade that could be useful in calculating bleeding risk. It is not used to identify older adults who are at risk for the development of bleeding disorders (response A). Responses C and D are incorrect. Clotting times are not related to thinness of blood or dissolving of clots.

Answer to Question 2

B
Platelets provide the foundation for the formation of the fibrin clot. Platelets do not affect the thickness or smooth flow of blood in the capillaries (response A). Responses C and D are also incorrect. Platelets do not have a role in the development of red blood cells and white blood cells, and the platelet level does not increase or decrease in response to an infection.
