Answer to Question 1

ANS: C
The chronic myeloproliferative disorders all have increased blood cells, although which one (or ones) varies depending on the condition. They also all have overlapping clinical features. The Philadelphia chromosome is only found in chronic myelogenous leukemia within this classification. Polycythemia vera uniquely has an increased red cell mass, and serious thromboembolic complications are primarily seen in essential thrombocythemia, although they also can be a complication of polycythemia vera when the patient is treated with phlebotomy only.

Answer to Question 2

ANS: B
Myeloblasts plus promyelocytes are usually present between 1 and 5 in chronic myelogenous leukemia. A total of 20 blasts plus promyelocytes is proposed for the classification of chronic myelogenous leukemia accelerated phase. All the other findings listed are characteristic of chronic myelogenous leukemia.

Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
