When planning care for a patient with hypoxia, which concept about erythropoietin should the nurse keep in mind?
A) Erythropoietin is released when renal blood flow increases.
B) Erythropoietin is released when oxygen content in the lungs is high.
C) Erythropoietin is released during anemic states.
D) Erythropoietin is stimulated by kidney damage.
C) Erythropoietin is released during anemic states.
Explanation: A) Erythropoietin is released into the plasma when peripheral tissues, especially the kidneys, are exposed to low oxygen concentrations. Erythropoietin is released (1) during anemia; (2) when blood flow to the kidneys decreases; (3) when the oxygen content of air in the lungs decreases due to disease or high altitude; and (4) when the respiratory surfaces of the lungs are damaged.
B) Erythropoietin is released into the plasma when peripheral tissues, especially the kidneys, are exposed to low oxygen concentrations. Erythropoietin is released (1) during anemia; (2) when blood flow to the kidneys decreases; (3) when the oxygen content of air in the lungs decreases due to disease or high altitude; and (4) when the respiratory surfaces of the lungs are damaged.
