Final answer:
The most appropriate nursing action is to inform the doctor about the client's inadequate urine output after their laparoscopic cholecystectomy, as it suggests possible issues with kidney function or hydration levels.
Step-by-step explanation:
The appropriate nursing action in the scenario where the client had a laparoscopic cholecystectomy at 8:00 a.m., and at 11:00 a.m. has stable vital signs, pain of 3/10, and has voided only 30 ml of urine, would be to inform the doctor about the client's inadequate urine output. Typically, after surgery, adequate urine output is necessary to demonstrate that the client's kidneys are functioning well and that the client is well-hydrated. An output of 30 ml in 3 hours post-operation is considered low as the expected urine output for an adult is at least 0.5 ml/kg/hr, and for most adults, this would equate to at least 100 ml/hr.
The client's complaint of pain, while important, is not as immediately concerning as the low urine output since their pain level is manageable at 3/10.
