Production in the yolk sac decreases at the beginning of the second trimester and the liver becomes the predominate source of red cell production. During the third trimester red cell production increases from the bone marrow and continues throughout life. 1. During the second trimester of pregnancy, where is the predominant site of red blood cell production? A) Yolk sac B) Bone marrow C) Lymph nodes D) Liver B) Red cell production increases rapidly within 24 hours; however, new red cells do appear in the blood for 5 days. 2. Following a blood donation, red cell production begins to increase in A) 30 minutes B) 24 hours C) 2 days D) 5 days E) 2 weeks D) A well-trained athlete will have a slightly elevated EPO level and the hematocrit will be elevated up to a value of 50%. A hematocrit higher than 50% suggests EPO treatment. 3. Olympic marathoners would most likely have what EPO and Hct levels? E) Aplastic anemia is a condition in which the bone marrow has a decreased production but does not respond to erythropoietin. Therefore, a person with aplastic anemia would have a low hematocrit and an elevated erythropoietin level. 4. Aplastic anemia patients would most likely have what EPO and Hct levels? A) With end-stage renal disease there is a decrease in erythropoietin level due to decreased release from the diseased kidneys. As a consequence of the decreased erythropoietin level, the hematocrit will be decreased. 5. End-stage renal disease patients would most likely have what EPO and Hct levels? B) With polycythemia vera the bone marrow produces red blood cells without a stimulus from erythropoietin. The hematocrit is very high, even up to 60%. With the elevated hematocrit there is a feedback suppression of erythropoietin and the erythropoietin levels are very low. 6. Polycythemia patients would most likely have what EPO and Hct levels D) The increase in RBC, WBC, and platelets suggests that the patient is suffering from polycythemia vera. Renal disease would result in a low EPO level, but the RBC count would be low. Myeloid leukemia would result in an increase in WBCs, with no increase in RBCs. Secondary polycythemia would have an elevated EPO level. Relative is due to dehydration. [Show More]
