Final answer:
The priority in the plan of care for a mother following her child's orchiopexy on an outpatient basis is monitoring for signs of infection.
Step-by-step explanation:
When planning discharge instructions for a mother whose child has undergone orchiopexy on an outpatient basis, the priority in the plan of care would be monitoring for signs of infection. This is because the surgical site is at risk for infection, as evidenced by the example of Barbara, who developed a localized infection after a catheter insertion. Detecting and treating infection early can prevent complications and promote healing.
Although other options like encouraging physical activity, administering pain medication, and applying warm compresses are important aspects of the plan of care, they are not the priority in this situation.
