Question 1

Which of these disorders usually demonstrates an elevated platelet count?

Accepted Answer

A)  Leukocytosis
B)  Anemia
C)  Polycythemia
D)  Thrombocytosis D

Question 2

Francee Jones is the CMA responsible for reviewing the laboratory results as she takes them from the printer. While reviewing the CBC results for Mr. Coffey, she notices his leukocyte count is 13,500/mm³. Is this result considered to be abnormal?

Accepted Answer

Yes, the leukocyte count (white blood cell count) of 13,500/mm^3 (or cells per microliter) for Mr. Coffey is considered to be abnormal. The normal range for leukocytes in adults typically falls between approximately 4,500 and 11,000 cells per microliter of blood. A count higher than 11,000 cells per microliter is generally considered leukocytosis, which can indicate an infection, inflammation, an immune system disorder, or other medical conditions. It is important for Francee Jones, as the Certified Medical Assistant (CMA) responsible for reviewing the laboratory results, to report this finding to the healthcare provider who ordered the test so that it can be interpreted in the context of the patient's overall health and any symptoms they may be experiencing. Further evaluation and diagnostic testing may be necessary to determine the cause of the elevated leukocyte count.
