A 19-year-old African-American college student comes to the student health center because of marked fatigue. Temperature is
38.3°C (101.0°F). Physical examination shows striking pallor of skin, nail beds and conjunctivae. There are petechial hemorrhages
in the skin of his legs. A soft, blowing systolic murmur is present over the precordium. No other abnormalities are present. Which
of the following is the most appropriate study at this time?
(A) Complete blood count
(B) Determination of bleeding and clotting time
(C) Examination of bone marrow aspirate
(D) Hemoglobin electrophoresis
(E) Serological testing for infectious mononucleosis

The correct answer is A
This description of a 19-year-old African-American student
includes a number of signs and symptoms consistent with anemia; i.e., marked fatigue,
striking pallor, and soft blowing systolic murmur (flow murmur). Petechial hemorrhages
may suggest a platelet disorder or vasculitis. The most important first study at this time
would be a CBC, which would reveal his hematocrit as well as his platelet count.
Although choices (choices B, C, D, and E) may all be appropriate, they would not be the
first tests ordered.
