A nurse is assessing a patient 2 hours after abdominal surgery. Which assessment finding would be the most concerning and require immediate intervention?

Absence of bowel sounds with abdominal distention 2 hours postoperatively indicates paralytic ileus or obstruction requiring immediate intervention. Other findings are expected or less urgent.

Correct Answer: 4

Clinical Reasoning and Analysis

The most concerning finding is the absence of bowel sounds in all four quadrants with abdominal distention and firmness. This clinical picture is highly suggestive of a paralytic ileus, a functional obstruction of the bowel, which is a common but serious complication following abdominal surgery. The handling of the intestines during surgery can cause a temporary cessation of peristalsis. While some degree of reduced bowel activity is expected, a completely silent abdomen with distention and a firm, board-like feel 2 hours postoperatively is an abnormal and alarming sign that requires immediate intervention. This presentation can indicate the progression from a normal postoperative ileus to a more severe, prolonged ileus or even an early sign of a mechanical obstruction or intra-abdominal complication. The distention and firmness suggest the accumulation of gas and fluid, which, if left unaddressed, can lead to increased intra-abdominal pressure, compromised respiratory function, splinting of the diaphragm, and potential fluid and electrolyte imbalances.

A systematic review and meta-analysis on nursing interventions for abdominal surgery patients emphasizes that effective postoperative monitoring and management are crucial for improving recovery and mitigating complications ^[1]. The assessment finding in option 4 directly contradicts the expected trajectory of recovery and falls outside the scope of standard postoperative care, demanding a proactive nursing response such as continued NPO status, nasogastric tube insertion if ordered, and immediate notification of the surgical team. While a case report on a massive hemorrhage from a pancreatic pseudocyst highlights the life-threatening nature of certain postoperative complications, it underscores the principle that vigilant assessment for signs of internal catastrophe, such as the acute abdomen presentation here, is paramount ^[2].

Analysis of Other Options

- Option 1: Blood pressure 110/70 mmHg, pulse 88 bpm, and temperature 99.1°F. These vital signs are within normal limits or show only a very slight elevation in temperature, which is a common physiological response to the stress of surgery and the inflammatory process. This would not be the priority concern.

- Option 2: Small amount of serosanguineous drainage on surgical dressing with intact edges. A small amount of serosanguineous (blood-tinged, serum-like) drainage is a normal and expected finding on a surgical dressing in the early postoperative period. The fact that the dressing edges are intact is a positive finding, indicating the wound is properly approximated and the drainage is not excessive or suggestive of an active bleed or dehiscence.

- Option 3: Patient reports incisional pain rated 6/10 with slight tenderness on palpation. Incisional pain is an expected outcome after abdominal surgery. A pain score of 6/10 indicates the need for pain reassessment and pharmacological or non-pharmacological intervention, but it is not the most immediately life-threatening finding. Effective pain management is a key nursing intervention for promoting recovery, as highlighted in the systematic review, but it is a lower priority than a potential ileus ^[1].
