ASCP Hematology Questions Questions
Question 1 of 5
Folic acid deficiency may develop in the following children EXCEPT
Correct Answer: C
Rationale: Goat’s milk (A), unfortified milk (B), phenytoin (D), and trimethoprim (E) impair folate intake or metabolism. Pasteurized cow’s milk (C) retains adequate folate, unlike unfortified formulas.
Question 2 of 5
Blood transfusion therapy in a child with sickle cell anemia is indicated in all the following conditions EXCEPT
Correct Answer: C
Rationale: Transfusions are indicated for acute chest syndrome (A), stroke (B), and splenic sequestration (E) in sickle cell anemia to improve oxygenation or reduce sickle cells. Chronic pain (C) and avascular necrosis (D) are managed symptomatically, not with transfusion.
Question 3 of 5
A healthy 5-mo-old boy appears pale. Examination is unremarkable. Lab findings include: Hb 8.1 g/dl; WBC 4,800/mm3; platelets 144,000/mm3; MCV, 111 fl; blood film showed hypersegmented neutrophils; serum B12, 65 pg/mL (low). The infant is vigorously breast fed. Of the following, the NEXT step of the management is
Correct Answer: B
Rationale: Low B12, macrocytic anemia, and hypersegmented neutrophils in a breastfed infant suggest maternal B12 deficiency. Checking maternal B12 (B) guides management, preceding treatment (C, D), transfusion (E), or Schilling test (A, less relevant in infants).
Question 4 of 5
All the following are correct regarding treatment of cold agglutinin disease EXCEPT
Correct Answer: D
Rationale: Cold agglutinin disease management includes avoiding cold (A), treating underlying causes (B), plasmapheresis (C), and rarely splenectomy (E). Glucocorticoids (D) are ineffective due to intravascular hemolysis.
Question 5 of 5
Transfusion of fresh frozen plasma (FFP) is efficacious for the treatment of deficiency of all the following coagulation factors EXCEPT
Correct Answer: D
Rationale: FFP provides factors V (A), X (B), XI (C), and protein C (E), but factor XIII (D) has low levels in FFP, requiring cryoprecipitate or concentrates for deficiency.
