A nurse is caring for an adolescent who is having a sickle cell crisis. Which of the following nursing actions should the nurse take?

A. Initiate a 2 L/day fluid restriction: Fluid intake should be increased, not restricted, during a sickle cell crisis to help prevent dehydration and improve circulation. B. Encourage exercise: Exercise is not recommended during a sickle cell crisis as it can worsen symptoms and lead to more complications. C. Assist with administering a blood transfusion: Blood transfusions are a common treatment during a sickle cell crisis to help increase the number of healthy red blood cells and decrease the risk of further complications. D. Withhold opioids to avoid dependence: Pain management is essential in a sickle cell crisis, and withholding opioids could lead to unnecessary suffering. Opioids should be given based on the severity of the pain.
