#On the seventh day after hemorrhage caused by a trauma, the following was revealed in a patient’s blood: erythrocytes - 2.8x1012/l, Hb - 3.9mmol/l, reticulocytes - 15%, acidophilic and polychromatophilic normoblasts were found in smear. What is the mechanism of appearance of regenerative forms of blood erythrocytes? -Going out of blood deposition -Increase permeability of erythrocyte sprout of bone marrow -Intensification of regeneration of erythroid cells in bone marrow +Inhibition of maturation of erythroid cells in bone marrow -Inhibition of synthesis of erythroprotein inhibitor #Singular oxyphilic normoblasts appeared in the blood of a patient after acute post-traumatic hemorrhage composing 15% of blood volume. On supravital staining 25% of reticulocytes were found. What is the patient anemia according to its ability of regeneration? +Hyperregenerative -Regenerative -Hyporegenerative -Aregenerative -Hypo- and aregenerative #A patient had anemia due to profuse blood loss. What blood changes are typical at the beginning of development of acute post-hemorrhagic anemia? -Presence of megalocytes in the blood -Absence of reticulocytes -Poikilocytosis, anisocytosis -Hyperchromia +Normochromia #While studying a blood smear different forms of erythrocytes were found. Which of them are regenerative? -Anisocytes -Poikilocytes +Polychromatophils -Ovalocytes -Megalocytes The experiment was carried out on a rabbit. The increase of the number of erythrocytes and hemoglobin in the blood due to the stimulation of erythropoiesis by erythropoietin was determined 2 weeks later after the narrowing of renal artery. What increases the formation of erythropoietin? -Hypoosmia -Hypercapnia +Hypoxemia -Hyperosmia -Hypovolemia #B12 folic deficiency anemia developed in a patient after stomach resection. What color index is typical for this disease? +1.30 -1.15 -1.0 -0.85 -0.70 #A victim of a car accident has lost much blood. What impairment of general blood volume takes place? -Simple hypovolemia -Polycythemic normovolemia -Olygocysthemic normovolemia -Polycystehmic hypovolemia +Oligocysthemis hypovolemia #Posthemorrhagic anemia has developed in a patient with periodical bleeding due to uterus fribromyoma. What type of chronic post hemorrhagic anemia takes place in this case? -Megaloblastic, hyperchromic, hyperegenerative -Megaloblastic, hypochromic, hyporegenerative -Erythroblastic, hyperchromic, hyporegenerative -Erythroblastic, hypochromic, hyperregenerative +Erythroblastic, hypochronic, hyporegenerative #What kind of disorders of total blood volume appears in case of absolute erythrocytosis? +Polycytemic hypervolemia -Oligocytemic hypervolemia -Oligocytemic hypovolemia -Simple hypervolemia -Simple hypovolemia #During the examination of adolescents that reside in mounting region increase in level of erythrocytes and hemoglobin in peripheral blood was found out. What is the reason for indicated erythrocytosis? +Exogenous hypoxia -Diseases of lungs -Congenital heart disease -Condensation of blood due to large loss of water -Vakes’s disease #B12 deficiency anemia was diagnosed in a man aged 57 after examination of him. Treatment was administered to this patient. Control blood test in this patient was performed in 3 years. What is the most adequate criterion for enhancement of erythropoiesis? +Increase in number of reticulocytes -Increase in hemoglobin content -Decrease in color index -Normoblastic hematopoiesis -Increase in number of leukocytes #Hypochromic anemia was diagnosed in a patient on the 7th day after acute hemorrhage. What mechanism is the leading one in its development? -Increase of iron excretion from the organism; -Impairment of globin synthesis; -Increased erythrocyte destruction in the spleen; -Impairment of iron absorption in the intestine; +Increased penetration of immature erythrocytes from bone marrow
