The production of erythroid precursor cells that are defective and undergo apoptosis in the bone marrow before they can be released into the bloodstream; causes anemia - Correct answer-Ineffective erythropoiesis Programmed cell death - Correct answer-Apoptosis What happens to defective precursor red cells in the bone marrow? - Correct answerApoptosis Impaired DNA synthesis as a result of vitamin B12/folate deficiency - Correct answerMegaloblastic anemia A sign of hematologic disorder observed in the mouth - Correct answer-Mucosal bleeding Response to acute or slowly developing anemia? - Correct answer-Tachycardia, increased respiratory rate, increased cardiac output, redistribution of blood to essential organs (heart, brain, muscles) Response to acute or slowly developing anemia? - Correct answer--Increase in erythrocyte 2,3-biphosphoglycerate (which decreases hemoglobin's affinity for oxygen and allows more oxygen release to tissues) and shifts o2 dissociation curve to right -increase in erythropoietin production by kidneys (which leads to increased erythropoiesis)
