A nurse is creating a plan of care for a child who has sickle cell anemia. Which of the following interventions should the nurse include in the plan?

A. Children with sickle cell anemia are at risk for dehydration, which can precipitate a sickling crisis. Encouraging adequate fluid intake is crucial to help maintain blood volume and reduce blood viscosity, decreasing the risk of vaso-occlusive episodes. B. Cold can trigger vasoconstriction, which worsens sickling and increases pain. Warm compresses or gentle heat are recommended to promote vasodilation and relieve discomfort. C. Children with sickle cell anemia, especially those receiving IV fluids or diuretics, are at risk for electrolyte imbalances, including hypokalemia. Monitoring for muscle weakness, arrhythmias, or irregular heartbeats is an essential safety measure in the plan of care. D. Meperidine is not recommended for children with sickle cell anemia due to the risk of neurotoxicity and seizures, especially with repeated dosing. Morphine or other opioids are preferred for managing severe pain in vaso-occlusive crises.
