A school-age child with sickle cell anemia is admitted with a vaso-occlusive crisis. Which nursing action should the nurse prioritize to effectively manage this acute complication and prevent further morbidity?

Promote bed rest without additional pain interventions to allow natural resolution of the crisis.

Limit fluid intake to prevent fluid overload and minimize risk of pulmonary edema during the crisis.

Administer prescribed opioids promptly and encourage oral hydration as tolerated to manage pain and reduce sickling episodes.

Delay opioid administration to assess the child's pain threshold and avoid potential opioid dependence.
