The patient, age 35, is admitted with aplastic anemia. He asks the nurse what aplastic anemia is. An accurate response would be that
the activity of the bone marrow is depressed.
red cells are absent as a result of chronic blood loss.
the bone marrow fails to produce lymphocytes.
the kidneys fail to produce red blood cells.
The Correct Answer is A
A. The activity of the bone marrow is depressed. Aplastic anemia is a condition where the bone marrow fails to produce sufficient numbers of blood cells, including red cells, white cells, and platelets.
B. Red cells are absent as a result of chronic blood loss. This describes a condition like iron- deficiency anemia, not aplastic anemia.
C. The bone marrow fails to produce lymphocytes. Aplastic anemia affects the production of all blood cells, not just lymphocytes.
D. The kidneys fail to produce red blood cells. This describes anemia of chronic kidney disease, not aplastic anemia. In aplastic anemia, the problem lies with the bone marrow, not the kidneys.
