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?

## 보기

1. Encourage a high-fiber diet to promote bowel regularity
2. Monitor fluid and electrolyte balance closely **✔ 정답**
3. Administer antidiarrheal medications as prescribed
4. Provide emotional support and stress management techniques

**정답: 2**

## 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.

Understanding the Priority in Acute Ulcerative Colitis Exacerbation

The client is presenting with a classic severe flare of ulcerative colitis (UC). The hallmark symptoms include frequent bloody diarrhea (8–10 episodes daily), severe abdominal cramping, and significant weight loss (15 pounds in one month) with clinical signs of dehydration. In the hierarchy of nursing priorities, physiological integrity and the management of acute, life-threatening complications take precedence. While all the listed interventions are relevant to the overall care plan for UC, the immediate priority must address the most urgent pathophysiological threat: fluid volume deficit and electrolyte imbalance.

Why Fluid and Electrolyte Monitoring Is the Priority

The client’s high-volume, bloody diarrhea leads to massive losses of water, sodium, potassium, and bicarbonate. This can rapidly progress to hypovolemic shock, cardiac dysrhythmias from hypokalemia, and metabolic acidosis. The reported fatigue and dehydration confirm that the client is already in a state of significant volume depletion. Before addressing nutrition, pharmacological symptom control, or psychosocial needs, the nurse must first stabilize the client's hemodynamic status. Closely monitoring intake and output, daily weights, vital signs, and serum electrolyte levels is the foundational step to guide fluid resuscitation and prevent life-threatening complications.

Analyzing the Incorrect Options Through a Priority Lens

- **Encourage a high-fiber diet to promote bowel regularity.** This is contraindicated during an acute flare. Insoluble fiber mechanically irritates the inflamed colonic mucosa, which can worsen abdominal cramping, diarrhea, and bleeding. The priority during an acute exacerbation is bowel rest, not stimulation. A low-residue or even clear liquid diet is typically indicated initially to minimize fecal stream trauma to the friable colon [1].

- **Administer antidiarrheal medications as prescribed.** While a provider may prescribe antidiarrheals, this is not the nurse's independent priority action. Furthermore, antimotility agents (e.g., loperamide, diphenoxylate/atropine) must be used with extreme caution in UC because slowing intestinal transit can lead to toxic megacolon, a life-threatening complication characterized by severe colonic dilation and risk of perforation. The nurse must first assess fluid status and ensure the prescription is safe before administering such medications.

- **Provide emotional support and stress management techniques.** Psychosocial support is an essential component of holistic care for a chronic, relapsing condition like UC. However, it is a lower-priority intervention when the client is facing an acute physiological crisis. According to Maslow’s hierarchy and the ABC (Airway, Breathing, Circulation) framework, addressing the immediate threat to circulation from hypovolemia takes clear precedence over coping and stress management.

Connecting the Intervention to the Underlying Pathophysiology and Current Evidence

The clinical rationale for prioritizing fluid and electrolyte balance is deeply rooted in the pathophysiology of a severe UC flare. The colonic mucosa is denuded and ulcerated, losing its ability to absorb water and electrolytes effectively. The resulting diarrhea is not just an inconvenience; it is a direct route for rapid vascular volume depletion. The provided evidence highlights a modern consideration in UC management: the potential harm of excessive caloric intake during hospitalization, which can induce hyperglycemia and increase infection risk [1]. This underscores that the acute phase is not about aggressively replacing lost weight with high-calorie nutrition, but rather about stabilizing the patient through careful physiological support, which begins with meticulous fluid and electrolyte management. The study’s focus on a short-term, calorie-restricted regimen to promote autophagy is a medical strategy employed only after the patient is hemodynamically stable, a state achieved through the nurse's priority intervention of monitoring and managing fluid balance [1].References (research sources)

## 임상 시나리오

Acute UC Exacerbation: Priority AssessmentStabilizing Fluid & Electrolyte Balance First
In a severe UC flare with 8-10 bloody stools/day, the immediate threat is hypovolemic shock from massive fluid and electrolyte loss. Monitor I&O, daily weights, and serum electrolytes (especially potassium) to guide resuscitation.

Do not confuse chronic management with acute priorities. Hemodynamic stability (vital signs, LOC) takes precedence over nutrition, medication, or psychosocial support during the initial presentation of a severe exacerbation.

CautionAvoid antidiarrheals (e.g., loperamide) and high-fiber foods in acute severe UC; they can precipitate toxic megacolon or worsen bowel irritation.

## 핵심 개념

- **Ulcerative Colitis** — A chronic inflammatory bowel disease causing continuous mucosal inflammation and ulceration in the colon and rectum, characterized by bloody diarrhea and abdominal cramping.
- **Hypokalemia** — Low serum potassium level, a critical complication of severe diarrhea that increases the risk of life-threatening cardiac dysrhythmias and muscle weakness.
- **Toxic Megacolon** — A severe complication of colonic inflammation involving acute colonic dilation and systemic toxicity, which can be precipitated by antidiarrheal medications.
- **ABC Framework** — A prioritization model in nursing (Airway, Breathing, Circulation) that guides immediate attention to life-threatening physiological needs such as fluid volume and circulatory status.
- **High-Output State** — A condition of excessive fluid loss, such as 8-10 stools per day, leading to rapid dehydration, electrolyte imbalances, and potential hypovolemic shock.
