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.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority of preoperative nursing interventions for a patient undergoing bowel resection due to colorectal cancer. The core principle is surgical safety and infection prevention. For any bowel surgery, mechanical cleansing (bowel prep) is a critical, time-sensitive intervention to empty the colon of fecal matter, thereby reducing the bacterial load and the risk of surgical site infection (SSI) and anastomotic leak (a life-threatening complication where the surgically reconnected bowel fails to heal). The patient's lab values (Hgb 9.2 g/dL, Hct 28%) indicate anemia, which is common in colorectal cancer due to chronic blood loss, but this does not supersede the immediate need for bowel preparation before surgery tomorrow.

Answer Rationale: Key Point! Option ① is correct because administering the prescribed bowel preparation is a time-dependent, safety-critical intervention. It must be completed before surgery to achieve its goal. Monitoring for electrolyte imbalances (like hypokalemia) is a key part of this intervention, as bowel prep solutions can cause significant fluid and electrolyte shifts. This directly addresses the ABCs (Airway, Breathing, Circulation) framework in a perioperative context by preventing a major postoperative circulatory complication (sepsis from an infected anastomosis).

Distractor Analysis:
  • Option ② (Pain management education): While important, detailed postoperative teaching is typically more comprehensive in the postoperative period. Preoperative teaching should be concise and focus on immediate pre- and post-op expectations. It is not the priority the day before surgery when a critical physical preparation remains.
  • Option ③ (Addressing body image): Psychosocial support is a vital part of holistic care, especially with surgeries that may result in a colostomy. However, according to Maslow's hierarchy and nursing priorities, physiological needs (preparing the body for safe surgery) take precedence over psychosocial needs in the immediate preoperative phase.
  • Option ④ (Reviewing consent): Verifying and witnessing the informed consent process is a crucial legal and ethical nursing responsibility. However, this should have been completed well in advance of the day before surgery. The nurse should ensure it's done, but it is not the clinical priority over a mandatory, time-sensitive physiological preparation like bowel cleansing.
Related Concepts: The NCLEX-RN frequently tests the ability to prioritize interventions using frameworks like ABCs (Airway, Breathing, Circulation), Maslow's Hierarchy of Needs, and acute vs. chronic or time-sensitive vs. non-urgent. In the perioperative setting, interventions that directly prevent life-threatening complications (infection, hemorrhage, respiratory compromise) are always prioritized.

Concept Summary
ConceptKey Points
Preoperative Bowel PrepMechanical cleansing to reduce fecal/bacterial load. Prevents surgical site infection (SSI) and anastomotic leak. Often involves oral solutions (e.g., PEG) and clear liquid diet.
Nursing Priorities (Framework)Use ABCs, Maslow's, and time-sensitivity. Physiologic safety (preventing harm) > psychosocial needs > health education in urgent prep phases.
Colorectal Cancer PresentationSigns: change in bowel habits, abdominal pain, rectal bleeding, unexplained weight loss, anemia (Hgb/Hct low).
Anastomotic LeakA surgical emergency. Leakage of bowel contents into abdomen causes peritonitis, sepsis. Symptoms: fever, tachycardia, severe abdominal pain, leukocytosis.

Side-by-Side Comparison!

Administer Bowel PrepHIGHEST (Time-critical)Directly impacts surgical outcome & patient safety. Cannot be delayed.
Review Surgical ConsentHigh (Should be done already)Legal/ethical must-do, but not the *clinical* priority if prep is pending.
Post-op Pain EducationModerate (Can be done post-op)Important for recovery, but not urgent for immediate pre-op safety.
Address Body Image ConcernsImportant (Ongoing process)Psychosocial need. Addressed after immediate physiological needs are met.

Anatomy, Physiology & Pharmacology Points
  • Bowel Prep Solutions: Common types include Polyethylene glycol (PEG) solutions (osmotic, less electrolyte shift) and sodium phosphate solutions (can cause significant electrolyte imbalances). Nursing role: ensure ingestion, monitor for nausea/vomiting, assess for dehydration.
  • Anemia in Colorectal Cancer: Often microcytic hypochromic anemia due to chronic iron loss from bleeding tumors. Pre-op Hgb may be optimized, but surgery often proceeds unless severely low.
  • Surgical Site Infection (SSI) Prevention: Bowel prep is a key component of the Surgical Care Improvement Project (SCIP) guidelines for colorectal surgery.

Memory Tips
  • Acronym: PREP for Pre-op Colorectal Priority: Prepare the bowel, Review labs (electrolytes), Educate briefly, Provide psychosocial support after.
  • Think: "Clean Bowel = Safe Surgery". You can't safely connect dirty pipes; the same goes for the bowel.

High-Frequency NCLEX Topics NCLEX loves to test priority-setting in the perioperative period. Remember: Key Point! Interventions that are time-dependent and prevent life-threatening complications always come first. Bowel prep, NPO status, and pre-op medications (like antibiotics) are classic high-priority answers.

Watch Out for Question Variations!
  • If the question adds: "The client has not signed the consent form," then Option ④ might become a parallel priority (legal safety), but the nurse would still need to coordinate bowel prep simultaneously.
  • If the question asks for the first action: "The nurse receives the order for bowel prep. What should the nurse do first?" The answer would be assess the client's understanding and ability to comply before administering.
  • If the scenario changes to postoperative day 1, priority shifts to pain management, assessing bowel sounds, and early ambulation to prevent atelectasis and ileus.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the day-shift nurse for Mr. Johnson, 58, admitted for a laparoscopic sigmoid colectomy tomorrow. He finished his clear liquid dinner and is now holding the gallon of PEG bowel prep solution, looking overwhelmed. His IV is infusing at 75 mL/hr for hydration. He says, "Do I really have to drink all of this? What if I get sick?"

Nursing Intervention Strategy:
  1. Assessment: Assess vital signs, baseline abdominal assessment, and electrolyte levels (especially potassium). Evaluate his anxiety level and readiness to learn.
  2. Education & Administration: Explain the why clearly: "This cleans out your colon so the surgery is safer and heals better." Provide practical tips: "Chill it, use a straw, sip it slowly over the next few hours. It's okay to take short breaks." Set a realistic schedule.
  3. Monitoring: Monitor intake and output closely. Stool output should eventually become clear liquid. Monitor for signs of dehydration (tachycardia, orthostatic hypotension) or electrolyte imbalance (muscle weakness, cramping).
  4. Support: Provide a bedside commode if needed. Ensure good perianal care supplies to prevent skin breakdown. Reassure him that nausea can occur and antiemetics can be given if prescribed.
  5. Coordination: Ensure the surgical consent is signed and on the chart. Communicate any concerns (e.g., inability to finish prep, severe cramping) to the surgeon.
Patient Safety and Precautions:
  • Contraindications: Bowel prep is typically contraindicated in suspected bowel obstruction or perforation.
  • Fall Risk: The patient will make frequent, urgent trips to the bathroom. Ensure the call light is within reach, the path is clear, and non-slip footwear is available.
  • Medication Hold : Confirm with the provider which medications (especially oral antihypertensives, diuretics, diabetes medications) should be held the night before/morning of surgery.

Nursing Procedure & Medication Flow Bowel Preparation Administration (PEG Solution Example):
  1. Verify the provider's order (type of solution, volume, timing).
  2. Assess patient for contraindications (allergies, ileus, renal impairment).
  3. Educate the patient on the process, goal (clear or yellow-tinged effluent), and self-care.
  4. Administer: Often 240 mL (8 oz) every 10 minutes until 4 liters are consumed or output is clear. Do not add flavorings unless specified, as they can alter electrolyte content.
  5. Monitor: Document volume ingested, character of stool output, patient tolerance, and any adverse effects (nausea, vomiting, bloating).
  6. Maintain IV hydration as ordered to counteract fluid losses.
  7. Final Check: Document completion and result of prep. Inform the surgical team if prep was inadequate.

A Word from Your Senior Nurse "In the rush of pre-op checks, never underestimate the power of clear, calm education about bowel prep. A patient who understands *why* they're drinking that unpleasant solution is far more likely to comply fully. Your vigilant monitoring for dehydration during this process is a direct act of patient safety—preventing a complication before it starts. On the NCLEX and at the bedside, always link your action to the prevention of the next worst possible outcome. Here, giving the prep prevents infection, which prevents sepsis. That's priority nursing thinking!"
