The Nurse Is Caring for a Patient Who Has Undergone

The nurse is caring for a patient who has undergone major abdominal surgery.The nurse notices that the patient's urine output has been less than 20 mL/hour for the past 2 hours.It is 0200 in the morning.The patient's blood pressure is 100/60 mm Hg,and the pulse is 110 beats per minute.Previously,the pulse was 90 beats per minute with a blood pressure of 120/80 mm Hg.The nurse should:

A) contact the provider and expect an order for a normal saline bolus.
B) wait until 0900 when the provider makes rounds to report the assessment findings.
C) continue to evaluate urine output for 2 more hours.
D) ignore the urine output, as this is most likely postrenal in origin.
