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. Assist with administering a blood transfusion. Blood transfusions are often necessary in sickle cell crisis to manage severe anemia and improve oxygen delivery to tissues. This action helps alleviate the symptoms of the crisis and prevent complications. B. Withhold opioids to avoid dependence. Opioids are essential for managing the severe pain associated with sickle cell crises. Concerns about dependence should not prevent adequate pain management in an acute setting. C. Encourage exercise. During a sickle cell crisis, rest is crucial to reduce oxygen demand and prevent further sickling of red blood cells. Exercise is contraindicated during a crisis. D. Initiate a 2 L/day fluid restriction. Adequate hydration is critical in managing sickle cell crisis, as it helps prevent further sickling of cells. Fluid restriction is inappropriate and could worsen the condition.
