Postoperative Day 2 After Sigmoid Colectomy: Expected Recovery or Anastomotic Leak?
Mr. Delgado, 58, is postoperative day 2 after an open sigmoid colectomy with primary anastomosis. His history includes type 2 diabetes (A1c 8.1%) and a 30-pack-year smoking history. At 0700 his vital signs are temperature 38.2 C, heart rate 114 and regular, blood pressure 104/62 (baseline 138/80), respiratory rate 22, and SpO2 94% on room air. His NG tube has drained 180 mL of dark green-brown fluid over the past shift, his Foley catheter has produced 70 mL of dark amber urine in 4 hours, and his midline incision with staples is tender but intact. He rates pain 7/10 and says it is deeper and different from yesterday. The abdomen is distended and firm with no bowel sounds in any quadrant. WBC is 15.8 with 12% bands, and lactate is 2.4 mmol/L. He is drowsy but oriented. The nurse is also assigned a client returning from thyroidectomy and a client waiting for discharge teaching.
1. Which of Mr. Delgado's findings are consistent with expected postoperative recovery, and which cluster suggests a complication? Explain the reasoning that separates the two.

Several findings are individually explainable on postoperative day 2: low-grade fever up to about 38.3 C, tachycardia driven by pain and fever, absent bowel sounds for 24-72 hours after abdominal surgery, serosanguineous NG drainage, tender but intact incision, and mild leukocytosis. None of these alone means leak.
The concern comes from the pattern and the trend: pain that is qualitatively new and deeper, a distended and firm abdomen with no bowel sounds at 48 hours, a heart rate of 114 with a blood pressure that is relatively low for him (104/62 versus a 138/80 baseline), oliguria with dark concentrated urine, bandemia, lactate 2.4, and SpO2 94%. Relative hypotension plus oliguria plus a rising lactate suggests inadequate perfusion, and with a fresh anastomosis the leading worry is a leak producing early intra-abdominal sepsis. The reasoning rule: one abnormal number is noise; converging abnormalities pointing at one organ system are signal. Other sources still need excluding - atelectasis, urinary infection, line infection, C. difficile - but the abdominal findings make leak the priority hypothesis.
2. Prioritize the nurse's actions for the next 30 minutes. What would you report, and which orders would you anticipate?

Immediately: stay with the client and call for help; place on continuous pulse oximetry and cardiac monitoring, vital signs every 15 minutes; apply oxygen to keep SpO2 at or above 94%; assess the abdomen and incision, and confirm IV patency (a second large-bore line is likely needed); keep him NPO; maintain NG to low intermittent suction; strict intake and output.
Notify the surgeon now, not at shift change - this is a time-critical change in condition. SBAR: situation (POD 2 colectomy with new deep pain, distension, tachycardia, oliguria); background (diabetes, smoking, baseline BP 138/80); assessment (suspected anastomotic leak with early sepsis, lactate 2.4, bandemia 12%); recommendation (urgent bedside evaluation, labs, imaging, antibiotics).
Anticipate: blood and urine cultures before antibiotics, repeat CBC, lactate, electrolytes, coagulation studies, type and screen, a crystalloid bolus, broad-spectrum IV antibiotics, and a CT abdomen and pelvis with contrast or a trip to the operating room. Avoid rectal temperatures or rectal medications and avoid oral intake.
3. How should the nurse manage the two other assigned clients while this is evolving?
Read the worked answer
The deteriorating client owns the nurse's attention, but leaving the other two unassessed is not acceptable either. The safe pattern is a rapid focused check plus escalation of staffing rather than trying to do everything personally.
The thyroidectomy client has a fresh neck incision with airway and bleeding risk - a compressed hematoma can obstruct the airway within minutes. Do a quick visual and respiratory assessment now (breathing pattern, voice, neck swelling, dressing), teach the call-light rule, and ask the charge nurse to take over q1h checks or reassign. The discharge-teaching client is hemodynamically stable and can safely wait; teaching is an RN function and cannot be delegated, so hand it off to another RN or delay it with an explanation and documentation.
Then ask the charge nurse for help or a temporary reassignment, document the assessments and the time the surgeon was notified, and give a structured handoff if the client leaves the unit. Prioritization reasoning: airway and perfusion threats outrank education and comfort, and delegation must never transfer ongoing assessment of an unstable client.
