Answer to Question 1

ANS: A
In acute DIC, the D dimer is elevated, along with the other laboratory findings listed. None of the other conditions listed have the prolonged PT and PTT, low fibrinogen, and elevated D dimers.

Answer to Question 2

ANS: C
Hemolytic uremic syndrome is found primarily in children between the ages of 6 months to 4 years. About 90 of the cases are caused by Shigella dysenteriae serotypes or enterohemorrhagic Escherichia coli OH serotypes, particularly O157:H7. Hyaline thrombi form in the renal vasculature, leading to renal failure, thrombocytopenia, and a microangiopathic hemolytic anemia with some red cell fragmentation.
