Which health teaching concept should the nurse emphasize when instructing the parents of a child with polycythemia caused by a congenital heart disorder?

The correct answer is Choice D.Choice A rationaleEncouraging progressive activity is generally beneficial for children with various health conditions, but it is not the primary focus for a child with polycythemia caused by a congenital heart disorder. The main concern is managing the increased blood viscosity and preventing complications related to it.Choice B rationaleExpecting the skin to turn yellow is not a typical symptom of polycythemia. Jaundice is more commonly associated with liver conditions or hemolytic diseases, not polycythemia caused by congenital heart disorders.Choice C rationalePreparing for seizures is not directly related to polycythemia. Seizures are more commonly associated with neurological conditions or severe electrolyte imbalances, not polycythemia.Choice D rationalePreventing dehydration is crucial for children with polycythemia because dehydration can increase blood viscosity, leading to a higher risk of thrombotic events. Ensuring adequate hydration helps maintain proper blood flow and reduces the risk of complications.
