Question

patient with a b12 deficiency has what type of anemia?
normocytic
microcytic
macrocytic

Explanation:

Vitamin B12 is essential for DNA synthesis. When there's a deficiency, red blood cell precursors (megaloblasts) in the bone marrow are unable to divide properly. This leads to the production of large (macrocytic) red blood cells. Normocytic anemia has normal - sized red blood cells, often seen in conditions like acute blood loss (before the body has time to compensate). Microcytic anemia has small red blood cells, typically due to iron deficiency (where the cell cannot make enough hemoglobin, so the cell size is reduced as it matures).

Answer:

Macrocytotic
