KROK 1 2019 – Question 90 · KROK (Medicine) · Pathophysiology
A patient is diagnosed with severe B12-deficiency anemia resulting in disturbed hematopoiesis and appearance of atypical erythrocytes in the blood. The patient has a history of total gastric resection. This diagnosis can be confirmed if the following cells are present in the peripheral blood:
- A. Normocytes
- B. Anulocytes
- C. Elliptocytes
- D. Megalocytes
- E. Microcytes
Hint
Ask what the loss of the stomach removes from vitamin absorption, and how blocked DNA synthesis in erythroid precursors changes the red cells that reach a blood smear.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
