A patient's CBC shows a hemoglobin of 8.5 g/dL. This finding is most consistent with which condition?

Accepted Answer

Anemia

Answer

A hemoglobin below the normal range (13.5–17.5 g/dL for males, 12–15.5 g/dL for females) indicates anemia.

Which stain is most commonly used to differentiate the morphology of blood cells in a peripheral blood smear?

Accepted Answer

Wright-Giemsa stain

Answer

Wright-Giemsa stain is the standard differential stain used in hematology to identify and differentiate blood cell types on a peripheral smear.

Question 4

What does the Mean Corpuscular Volume (MCV) measure in a CBC?

Accepted Answer

Average size of red blood cells

Answer

MCV measures the average volume (size) of individual red blood cells, expressed in femtoliters (fL), used to classify anemia types.
