What rationale explains why prolonged use of oxygen should be discouraged in a child with anemia?
a. Prolonged use of oxygen can decrease erythropoiesis.
b. Prolonged use of oxygen can interfere with iron production.
c. Prolonged use of oxygen interferes with a child's appetite.
d. Prolonged use of oxygen can affect the synthesis of hemoglobin.
ANS: A
Oxygen administration is of limited value, because each gram of hemoglobin is able to carry a limited amount of the gas. In addition, prolonged use of supplemental oxygen can decrease erythropoiesis. Prolonged use of oxygen does not interfere with iron production, a child's appetite, or affect the synthesis of hemoglobin.
