Clinical signs and symptoms Verified Answer -c. RBC indices Reticulocytosis usually indicates a. accelerated erythropoiesis b. neoplastic process c. aplastic anemia d. response to inflammation Verified Answer -a. accelerated erythropoiesis RBC morphology in sickle cell trait is typically a. normocytic, normochromic b. normocytic, hypochromic c. microcytic, normochromic d. microcytic, hypochromic Verified Answer -a. normocytic, normochromic Which of the following will NOT be found on the hemoglobin electrophoretic pattern of a patient with sickle cell disease? a. 20% - 40% Hemoglobin A b. 5% - 20% Hemoglobin F c. 2% - 4% Hemoglibin A1 d. 80% - 95% Hemoglobin S Verified Answer -A. 20% - 40% Hemoglobin A Methemoglobinemia is characterized by all of the following EXCEPT: a. can be caused by deficiency of methemoglobin b.
