Final answer:
The nurse should monitor patient urine output to evaluate the need for the current plan of care.
Step-by-step explanation:
In this situation, the nurse should monitor patient urine output to evaluate the need for the current plan of care. Just because the patient has met the short-term goal of urinating within 1 hour after surgery, it doesn't necessarily mean that the plan of care can be discontinued. By monitoring the patient's urine output, the nurse can assess if the current plan of care is still necessary or if adjustments need to be made.
