Answer to Question 1

ANS: D
Only the platelet count, of those evaluations listed, is normal in a patient who regularly takes aspirin. Aspirin acetylates cyclooxygenase, which is necessary for the synthesis of thromboxane A2. This prolongs the bleeding time.

Answer to Question 2

ANS: D
Patients with one of the chronic myeloproliferative disorders, such as polycythemia vera and essential thrombocythemia, may have abnormal platelet function; clinically, they may result in either abnormal bleeding or abnormal thrombosis. Some patients develop both, although this is rare.
