A bone marrow examination was ordered on a patient with a 6.8 g/dL hemoglobin. The examination revealed an increase in fibrous tissue. This is an indication that the anemia is likely the result of a:
A) Proliferation defect
B) Nuclear maturation defect
C) Survival defect
D) Cytoplasmic maturation defect

Question

Quizplus · Accepted Answer

An increase in fibrous tissue suggests a proliferation defect, meaning that the bone marrow is not producing enough blood cells. This can lead to a decrease in hemoglobin levels and anemia. A nuclear maturation defect would show abnormal maturation of the nucleus in the blood cells, a survival defect would show premature destruction of blood cells, and a cytoplasmic maturation defect would show abnormal maturation of the cytoplasm in the blood cells. None of these defects are suggested by an increase in fibrous tissue.
