A patient who is postoperative day 1 following a CABG has produced 20 mL of urine in the past 3 hours and the nurse has confirmed the patency of the urinary catheter. What is the nurse's most appropriate action?
A) Document the patient's low urine output and monitor closely for the next several hours.
B) Contact the dietitian and suggest the need for increased oral fluid intake.
C) Contact the patient's physician and suggest assessment of fluid balance and renal function.
D) Increase the infusion rate of the patient's IV fluid to prompt an increase in renal function.
Ans: C
Feedback:
Nursing management includes accurate measurement of urine output. An output of less than 1 mL/kg/h may indicate hypovolemia or renal insufficiency. Prompt referral is necessary. IV fluid replacement may be indicated, but is beyond the independent scope of the dietitian or nurse.
