Corrective surgery for hypertrophic pyloric stenosis is completed, and the infant is returned to the pediatric unit with an intravenous (iv) infusion in progress. what is the priority nursing action?

The answer would be: Apply adequate restraints

The infant just had a surgery and probably still in effect of the sedatives. When the sedative stopped, the infant might remove the i. v. line. It is important to keep the intravenous infusion intact by giving restraint. Using sedative could work but it will be dangerous and less safe. Assessing for infiltration is not related to the condition.
