A nurse is caring for a 45-year-old client with ulcerative colitis admitted with an acute exacerbation, complaining of severe abdominal cramping, bloody diarrhea (8-10 stools per day), fatigue, dehydration, and a 15-pound weight loss over the past month. Which nursing intervention should be the priority?

해설
During an acute exacerbation of ulcerative colitis, monitoring fluid and electrolyte balance is the priority due to significant losses from bloody diarrhea. Other options are less critical or contraindicated in acute phase.

Core Nursing Explanation Key Concept Analysis: This question assesses the ability to prioritize nursing interventions for a patient experiencing an acute exacerbation of ulcerative colitis (UC). The core pathophysiology involves severe inflammation and ulceration of the colonic mucosa, leading to profuse, bloody diarrhea. This results in massive fluid, electrolyte, and blood loss, which can rapidly lead to hypovolemia, electrolyte imbalances (especially hypokalemia, hyponatremia), and metabolic acidosis. The priority in any acute situation follows the Key Point! ABCs (Airway, Breathing, Circulation) framework. Here, the threat to Circulation from dehydration and electrolyte imbalance is the most immediate life-safety concern.

Answer Rationale: Key Point! The correct answer is ② Monitor fluid and electrolyte balance closely. The patient's symptoms—bloody diarrhea (8-10 stools/day), fatigue, dehydration, and significant weight loss—are classic signs of a severe flare. This degree of fluid loss directly threatens circulatory volume and organ perfusion. Monitoring includes strict Intake and Output (I&O), daily weights, assessing for signs of dehydration (tachycardia, hypotension, poor skin turgor), and reviewing lab values like serum sodium, potassium, chloride, and bicarbonate. This intervention is foundational; correcting fluid and electrolyte deficits is essential before other treatments can be fully effective and to prevent complications like renal failure or cardiac arrhythmias.

Distractor Analysis:
  • ① Encourage a high-fiber diet to promote bowel regularity: Watch out for confusion! This is contraindicated during an acute exacerbation. High-fiber foods are rough and can further irritate the inflamed, ulcerated bowel mucosa, worsening pain and diarrhea. Dietary management during a flare typically involves a low-residue or elemental diet to rest the bowel.
  • ③ Administer antidiarrheal medications as prescribed: While antidiarrheals like loperamide may be used cautiously in some chronic IBD management, they are generally avoided or used with extreme caution during severe acute flares. They can slow intestinal motility to the point of causing toxic megacolon, a life-threatening complication where the colon dilates and may rupture.
  • ④ Provide emotional support and stress management techniques: This is an important supportive intervention, as stress can exacerbate UC. However, it is not the priority when the patient has immediate physiological instability from fluid and electrolyte losses. Psychosocial care is addressed after stabilizing the acute physical crisis.
Related Concepts: The nursing process dictates addressing physiological needs (Maslow's Hierarchy) before psychological ones. In gastrointestinal disorders with profuse output, the nursing diagnosis of Deficient Fluid Volume often takes precedence. Understanding the difference between management of UC in remission versus acute exacerbation is critical.

Concept Summary
ConceptKey Takeaway
Ulcerative Colitis (UC) PathoContinuous mucosal inflammation/ulceration of colon/rectum → bloody diarrhea, fluid/electrolyte loss.
Priority in Acute ExacerbationABCs: Address Circulation threat first (fluid/electrolyte imbalance).
Key Monitoring ParametersStrict I&O, daily weights, vital signs (orthostatic), labs (Na+, K+, Cl-, HCO3-).
Contraindicated in Acute FlareHigh-fiber diet, routine use of antimotility drugs (risk of toxic megacolon).
Nursing Diagnosis PriorityDeficient Fluid Volume > Acute Pain > Imbalanced Nutrition: Less Than Body Requirements.

Side-by-Side Comparison!
FeatureUlcerative Colitis (UC)Crohn's Disease
Inflammation PatternContinuous, mucosal only (superficial).Skip lesions, transmural (full-thickness).
Primary LocationColon and rectum (always involves rectum).Anywhere from mouth to anus (often terminal ileum).
Stool CharacteristicBloody, mucoid diarrhea.Non-bloody (unless severe), may have steatorrhea.
Acute Phase PriorityBoth: Fluid/electrolyte balance. UC-specific: Monitor for toxic megacolon.Both: Fluid/electrolyte balance. Crohn's-specific: Monitor for fistulas, obstruction.

Anatomy, Physiology & Pharmacology Points
  • Anatomy/Physiology: The colon's main functions are water and electrolyte reabsorption. In UC, inflamed mucosa cannot perform this, leading to secretory diarrhea with fluid/electrolyte loss.
  • Pharmacology: First-line drugs for UC flares are 5-aminosalicylates (5-ASA) (e.g., mesalamine) and corticosteroids (e.g., IV methylprednisolone) to reduce inflammation. Antidiarrheals are used with caution.

Memory Tips
  • Priority Mnemonic: "FLUID FIRST" for Flares. Fluid Loss Undermines Immediate Defenses – Fix Rehydration & Ions Stat!
  • Diet Tip: Remember "Low and Slow" for acute UC: Low-residue diet, Slow reintroduction of foods during remission.
  • Contraindication: "Fiber and Flare don't mix." "Antidiarrheals can lead to a Toxic (megacolon) situation."

High-Frequency NCLEX Topics NCLEX loves testing priority-setting in unstable patients. Ulcerative colitis is a classic scenario where a distractor like "emotional support" seems caring, but physiological stability (fluid balance) is always the priority. Be ready to identify lab values indicating dehydration (elevated BUN, creatinine, hematocrit) or hypokalemia (muscle weakness, EKG changes).

Watch Out for Question Variations!
  • Instead of asking for the priority intervention, the question might ask: "Which finding requires immediate intervention?" (Answer: Tachycardia and hypotension).
  • It could present lab results: "Serum K+ is 2.8 mEq/L. Which action is priority?" (Answer: Initiate potassium replacement per protocol while monitoring cardiac rhythm).
  • It might shift to patient education for remission: "Which statement by the client indicates understanding of maintenance therapy?" (Correct answer would involve medication adherence and identifying trigger foods, not high-fiber diet during a flare).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 45, is admitted with a diagnosis of UC exacerbation. He is pale, has dry mucous membranes, and reports feeling lightheaded when standing. His vital signs are: BP 100/60 (from 130/80 baseline), HR 118, RR 22. He has had 8 bloody, liquid stools in the last 12 hours.

Nursing Intervention Strategy:
  1. Assessment: Perform a focused assessment: Orthostatic vital signs, abdominal assessment (listen for bowel sounds, note tenderness), strict measurement of all stool output (volume, character), daily weight on the same scale. Assess skin turgor and capillary refill.
  2. Planning & Implementation: The priority plan is to restore fluid volume and electrolyte balance.
    • Initiate IV therapy as ordered (typically isotonic solutions like 0.9% NaCl).
    • Maintain strict I&O: Measure every stool, emesis, and urine output. All IV and oral intake must be recorded.
    • Monitor labs: CBC (for anemia), electrolytes, BUN/Cr, albumin.
    • Collaborate with the dietitian to initiate a low-residue, high-protein, high-calorie diet or NPO (Nothing by Mouth) if severe, with possible TPN (Total Parenteral Nutrition) support.
    • Administer prescribed medications (IV steroids, 5-ASA) on time.
    • Provide perianal care with each stool: Use gentle cleansing with water and a soft cloth, apply barrier ointment (e.g., zinc oxide) to protect skin from breakdown.
  3. Evaluation: Evaluate effectiveness by tracking trends: Is urine output >30 mL/hr? Are vital signs stabilizing? Is stool frequency decreasing? Are electrolyte levels normalizing?
Patient Safety and Precautions:
  • Toxic Megacolon: This is a medical emergency. Monitor for Key Point! abdominal distention, decreased or absent bowel sounds, fever, tachycardia, and signs of peritoneal irritation. Report these immediately. Avoid narcotics and anticholinergics which can precipitate it.
  • Medication Caution: Do not administer antidiarrheals without a specific, cautious order from the provider familiar with the patient's acute status.
  • Infection Control: Practice strict hand hygiene and contact precautions as bloody diarrhea can be infectious and poses a risk to the patient and others.

Nursing Procedure & Medication Flow Managing IV Fluids for Dehydration:
  • Calculation: Fluid replacement rate is based on deficit + maintenance + ongoing losses. For example, if a patient has a 2L deficit, maintenance is 1500 mL/day, and has 500 mL of stool output, the 24-hour goal might be ~4000 mL.
  • Monitoring: Assess for signs of overhydration (crackles in lungs, edema, jugular venous distention) as well as underhydration, especially in patients with cardiac comorbidities.
Medication Administration:
  • IV Corticosteroids (e.g., Methylprednisolone): Administer via IV pump over the prescribed time (e.g., 30-60 minutes). Monitor for side effects: hyperglycemia, mood changes, insomnia, increased infection risk.
  • 5-ASA Drugs (e.g., Mesalamine): Can be oral or rectal (enema/suppository). Ensure rectal formulations are retained as long as possible. Teach the patient proper administration if for home use.

A Word from Your Senior Nurse "In the whirlwind of an acute UC flare, your patient is losing not just fluid, but also hope. Your priority action—vigilantly monitoring fluid and electrolytes—is what keeps them physiologically safe. But never forget the person in the bed. While you're checking their IV site and logging output, a simple, "This must be so exhausting for you," acknowledges their struggle. That balance of sharp clinical skills and deep human compassion is the heart of nursing. For the NCLEX, master the 'why' behind the priority: dehydration kills faster than anxiety. In clinicals, you'll see it firsthand—the patient who perks up after liters of normal saline is a testament to your foundational care. You've got this!"
