2. location of joint replacements
3. history of fractures
4. carbohydrate intake

Rationale: Red blood cells arise from the myeloid cell line in the red bone marrow and mature in the blood or spleen. Erythrocyte production is tightly regulated by erythropoietin, a circulating hormone that is primarily produced by the kidneys. It is believed that erythropoietin may be produced in the renal tubular cells, which are major consumers of oxygen that are particularly sensitive to lowering oxygen levels. In a patient with a low red blood cell count, the patient's renal function should be further assessed. Even though red blood cells do originate in the marrow of the ribs, sternum, and femur, joint replacements will most likely not impact red blood cell formation. A history of fractures will not impact the patient's current red blood cell formation. Production of red blood cells requires certain levels of adequate nutrients which include protein, multivitamins, and nutrients. The patient's carbohydrate intake will not affect red blood cell production.
