Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a surgical floor. Mr. Jones, 58, is post-op day 1 from a left radical nephrectomy for renal cell carcinoma. His vital signs are stable, but he is drowsy from patient-controlled analgesia (PCA).
Nursing Intervention Strategy:1. Assessment: Every hour, measure and document urine output from the Foley catheter. Calculate mL/kg/hr. Assess urine color (should be yellow/amber; report bloody or cola-colored urine). Monitor vital signs, especially blood pressure (hypotension reduces renal perfusion). Review daily BUN and Creatinine lab results.2. Planning & Implementation: If urine output drops below 30 mL/hr, first check for simple causes: Is the Foley catheter kinked or blocked? Is the IV fluid infusing? Then, increase IV fluid rate per protocol/order if the patient is not fluid overloaded. Notify the surgeon promptly if low output persists.3. Education: Once stable, educate the patient on lifelong kidney protection: avoid NSAIDs (e.g., ibuprofen), stay well-hydrated, control blood pressure, and report any signs of urinary tract infection or flank pain.
Patient Safety and Precautions:• Key Point! Never clamp a Foley catheter post-nephrectomy without an order. Urine output must be allowed to drain freely for accurate measurement.• Be alert for signs of bleeding (another major post-nephrectomy complication): tachycardia, hypotension, decreasing hemoglobin, flank pain, or swelling.• When encouraging ambulation (intervention ②), ensure the patient is assisted, has adequate pain control, and is not orthostatic.
Nursing Procedure & Medication Flow
Urine Output Monitoring Procedure:1. At the beginning of your shift, note the baseline amount in the Foley drainage bag.2. Every hour, mark the time and measure the volume drained.3. Document: "Time 0800-0900: Urine output 55 mL, clear yellow. Total for shift: ___ mL."4. Report immediately: "Urine output <30 mL for 2 consecutive hours" or any significant change.
Analgesic Administration (Intervention ③) Caution:• Assess pain using a scale before and after administration.• For PCA, monitor respiratory rate and sedation level closely (opioids can cause respiratory depression).• Avoid nephrotoxic analgesics like ketorolac (Toradol) unless specifically ordered and with close renal monitoring.
A Word from Your Senior Nurse
"In the real world, the first thing I do when I get report on a post-nephrectomy patient is go straight to the room and look at the Foley bag. I check the urine color and the hourly output on the intake/output (I&O) sheet. That one piece of data tells me a huge story about how that remaining kidney is handling the stress of surgery. NCLEX wants you to think like a nurse who protects their patient from the worst possible complication first. In this case, kidney failure is that worst complication. So, while getting your patient up to walk and managing their pain are on your list, your eyes and brain need to be locked on that urine output. That's how you move from being a student who knows the right answer to a nurse who instinctively does the right thing."
