Answer to Question 1
B
Sickle cell anemia is a chronic inherited disease in which structurally defective hemoglobin molecules lead to hemolysis, anemia, and pain in areas of the body where the defective red blood cells block normal blood flow. It occurs mostly in blacks and in some people from the Mediterranean region. In people with sickle cell anemia, a crisis may be triggered by changes in altitude, dehydration, and infection. The patient's ethnicity, symptoms, and laboratory test results should suggest the possibility of sickle cell anemia more than TIA or infection.
