Question

Quizplus · Accepted Answer

A high hemoglobin level is expected in a child with a cyanotic heart defect due to chronic hypoxia stimulating erythropoietin production to increase hemoglobin levels in an attempt to compensate for low oxygen levels.

Answer: D
 A low hematocrit level may also be expected in a child with a cyanotic heart defect due to chronic hypoxia causing plasma expansion and dilution of red blood cells.

Therefore, both options C and D are correct.
