Question 1 of 5
Which of the following is false regarding heparin?
Correct Answer: A
Rationale: Heparin is an anticoagulant with several true properties: it binds to antithrombin III to inhibit thrombin (C), protamine sulfate reverses its effects (D), and partial thromboplastin time monitors its use (E, implied). Subcutaneous injection can cause hematomas, but it’s not avoided—it’s a common administration route (A is true). Heparin is not 'stored' in mast cells (B); it’s produced by mast cells and basophils but released, not stored, making B false.
Question 2 of 5
Graft versus host disease is a complication of transfusion in patients of bone marrow transplantation. This can be best avoided by
Correct Answer: B
Rationale: Graft-versus-host disease (GVHD) occurs when donor lymphocytes attack the recipient. Irradiating blood components (B) inactivates lymphocytes, preventing GVHD in bone marrow transplant patients. Packed cells (A) or fresh blood (C) don’t eliminate lymphocytes, crystalloids (D) aren’t transfusions, and relative donors (E) increase risk—irradiation is standard.
