A nurse is caring for a client with colorectal cancer who is scheduled for a bowel resection surgery tomorrow. Which nursing intervention should be the priority in the preoperative preparation?
A 58-year-old client with colorectal cancer is admitted for surgical resection. The client reports abdominal cramping, changes in bowel habits, and weight loss over the past 3 months. Laboratory results show hemoglobin 9.2 g/dL and hematocrit 28%. The client appears anxious about the upcoming surgery and asks many questions about the procedure.

Bowel preparation is the priority to reduce bacterial contamination and prevent postoperative complications like anastomotic leaks. Other options are important but less urgent for preoperative safety.
Understanding the Priority: Preoperative Bowel Preparation
The correct answer is 1. Administering the prescribed bowel preparation solution and monitoring for electrolyte imbalances is the priority nursing intervention for this client in the immediate preoperative period.
Why Bowel Preparation is the Priority
For a client undergoing colorectal surgery, effective bowel preparation is a critical safety intervention. The primary goal is to reduce the bacterial load in the colon and eliminate solid fecal matter. This mechanical cleansing directly decreases the risk of devastating postoperative complications, such as anastomotic leakage, surgical site infection, and peritonitis. An evidence synthesis on perioperative intestinal rehabilitation for colorectal cancer patients emphasizes that a structured intestinal rehabilitation plan, which includes preoperative bowel preparation, is fundamental to clinical nursing practice to optimize surgical outcomes [1]. The nurse’s priority is to safely execute this prescribed medical intervention, which is time-sensitive and must be completed before the surgery.
The Critical Link: Monitoring for Electrolyte Imbalances
The administration of bowel preparation solutions, particularly those with an osmotic action, causes a large-volume fluid shift into the gastrointestinal tract, leading to profound fluid and electrolyte losses. This client presents with a significant risk factor that makes this monitoring the absolute priority: pre-existing anemia, evidenced by a hemoglobin of 9.2 g/dL and hematocrit of 28%. Preoperative anemia is a common and serious finding in colorectal cancer patients, significantly associated with increased morbidity and mortality [3]. A patient with anemia has a reduced physiological reserve, making them highly vulnerable to the hypovolemia and electrolyte disturbances (such as hypokalemia and hyponatremia) that can be induced by bowel preparation. Such imbalances can precipitate cardiac dysrhythmias, hemodynamic instability, and increased surgical risk. Therefore, the act of administering the preparation is inseparable from the vigilant nursing assessment and management of its life-threatening consequences.
Why Other Options Are Not the Immediate Priority
While all options represent valid nursing concerns, they do not take precedence over a time-sensitive, safety-critical medical intervention.
- Option 2 (Pain management education): Providing information about postoperative pain management is an essential part of preoperative teaching. However, this is a psychosocial and educational intervention that can be effectively performed after the physical preparation tasks are initiated or completed. It does not pose an immediate physiological threat if delayed.
- Option 3 (Body image feelings): Addressing psychosocial needs, such as expressing feelings about potential body image changes, is a crucial aspect of holistic nursing care. However, psychosocial support is a lower priority than a physiological intervention that directly prevents surgical complications. This conversation can and should occur, but not before ensuring the client’s physical safety for the procedure.
- Option 4 (Surgical consent): Reviewing the surgical consent form is a fundamental legal and ethical nursing responsibility. However, the scenario states the surgery is already scheduled for tomorrow, implying the consent process has been initiated and the form is likely already signed. The nurse’s role is to verify the signed form is in the chart and that the client’s questions have been addressed by the surgeon. The immediate, time-critical task is the initiation of bowel preparation, without which the surgery cannot safely proceed. Best evidence for preoperative management in intestinal surgery underscores that while stoma site marking and education are vital, the physical preparation of the bowel is a foundational step that must be executed systematically .

Preoperative Bowel Prep for Colorectal SurgeryPrioritizing safety and monitoring in the anemic patient
Administer the prescribed bowel preparation solution as a time-critical safety task to reduce bacterial load and prevent anastomotic leak or peritonitis.
Closely monitor for electrolyte imbalances (e.g., hypokalemia, hyponatremia) due to large-volume fluid shifts from osmotic solutions. This is especially critical in patients with pre-existing anemia (Hgb 9.2 g/dL), who have reduced physiological reserve.
Caution
Never administer bowel prep to a patient with a suspected bowel obstruction or perforation. Assess for severe abdominal pain or rigidity before starting.
Bowel Preparation — Mechanical cleansing of the colon using osmotic or stimulant solutions to reduce fecal matter and bacterial load, minimizing the risk of anastomotic leak and surgical site infection.
Electrolyte Imbalance — A disturbance in the concentration of ions (e.g., sodium, potassium) in the body, often caused by large-volume fluid shifts from bowel prep, leading to cardiac dysrhythmias or weakness.
Anastomotic Leak — A serious postoperative complication where the surgical connection between two bowel segments fails, allowing intestinal contents to spill into the sterile peritoneal cavity.
Priority Setting — A clinical judgment model (e.g., Maslow's hierarchy, ABCs) used to rank nursing actions, placing physiological safety and time-critical interventions above psychosocial needs.
