ANormocytic
BMicrocytic
CMacrocytic
DPoikilocytic
Answer & Solution
Correct answer: C. Macrocytic
1. The morphological approach classifies anemia by the size of the red cells themselves, measured as mean corpuscle volume.
2. Normal-sized cells are normocytic.
3. Smaller-than-normal cells are microcytic.
4. Larger-than-normal cells are macrocytic, which is the answer here.
5. Micro and macro are easy to swap under time pressure, so the microcytic option is the built-in trap.
