Diarrhea is defined as the frequent passage of loose, watery stools that often lead to dehydration, electrolyte imbalances, and malnutrition if left untreated. It can be a symptom of various underlying conditions such as infections, gastrointestinal disorders, or food intolerance.
Definition of Diarrhea
According to the American Gastroenterological Association, diarrhea is typically defined as having three or more loose or liquid bowel movements per day.
It can be categorized as acute, persistent, or chronic depending on the duration and severity of the symptoms.
Common Causes of Diarrhea
- Infections (bacterial, viral, or parasitic)
- Food intolerances (e.g., lactose intolerance)
- Medications (e.g., antibiotics)
- Inflammatory bowel diseases (e.g., Crohn’s disease, ulcerative colitis)
- Malabsorption syndromes
- Stress or anxiety
Pathophysiology of Diarrhea
Diarrhea occurs when the intestine fails to absorb fluids and electrolytes adequately or when it secretes excessive amounts of fluids, overwhelming the absorptive capacity of the bowel.
This imbalance in fluid absorption and secretion results in frequent, watery bowel movements, dehydration, and electrolyte loss.
Nursing Diagnosis for Diarrhea
The primary nursing diagnosis for diarrhea includes:
- Diarrhea related to infection or inflammatory process as evidenced by frequent, loose stools.
- Risk for electrolyte imbalance related to excessive fluid loss secondary to diarrhea.
- Risk for dehydration related to frequent passage of watery stools.
- Imbalanced nutrition: less than body requirements related to malabsorption and loss of nutrients through diarrhea.
- Impaired skin integrity related to frequent episodes of diarrhea.
5 Nursing Care Plans for Diarrhea
Nursing Care Plan 1: Diarrhea Management
Nursing Diagnosis: Diarrhea related to infection or gastrointestinal disorders as evidenced by frequent, watery bowel movements.
Goal: The patient will demonstrate improved bowel function with fewer episodes of diarrhea within 48 hours.
Nursing Interventions:
- Assess stool characteristics (color, consistency, frequency) to determine the severity and cause of diarrhea.
- Administer antidiarrheal medications as ordered (e.g., loperamide) to reduce bowel motility and frequency of diarrhea.
- Encourage fluid intake (e.g., oral rehydration solutions, clear fluids) to prevent dehydration and replace lost fluids.
- Monitor intake and output to evaluate the effectiveness of fluid replacement and the patient’s hydration status.
- Encourage a BRAT diet (bananas, rice, applesauce, toast) to reduce irritation and promote normal bowel function.
Evaluation: The patient reports a reduction in the frequency of diarrhea and maintains adequate hydration.
Nursing Care Plan 2: Risk for Electrolyte Imbalance
Nursing Diagnosis: Risk for electrolyte imbalance related to excessive fluid loss secondary to diarrhea.
Goal: The patient will maintain balanced electrolyte levels, as evidenced by normal laboratory results (e.g., potassium, sodium).
Nursing Interventions:
- Monitor serum electrolyte levels (especially sodium and potassium) regularly to detect any imbalances early.
- Provide electrolyte-rich fluids (e.g., sports drinks, electrolyte solutions) to replace lost electrolytes and maintain balance.
- Monitor vital signs (blood pressure, heart rate) for signs of electrolyte imbalance such as hypotension or arrhythmias.
- Educate the patient on the importance of electrolyte replacement during episodes of diarrhea.
Evaluation: The patient’s electrolyte levels remain within normal limits, and no signs of imbalance are observed.
Nursing Care Plan 3: Risk for Dehydration
Nursing Diagnosis: Risk for dehydration related to frequent passage of watery stools.
Goal: The patient will remain hydrated, as evidenced by stable vital signs, moist mucous membranes, and adequate urine output.
Nursing Interventions:
- Assess the patient’s hydration status regularly by checking skin turgor, mucous membranes, and daily weights.
- Administer intravenous fluids if oral intake is insufficient to maintain hydration.
- Encourage oral rehydration by providing small, frequent sips of water or electrolyte solutions.
- Monitor urine output closely, noting any decrease in quantity or change in color, which could indicate dehydration.
- Teach the patient about recognizing signs of dehydration, such as dizziness, dry mouth, and reduced urine output.
Evaluation: The patient maintains proper hydration with stable vital signs and normal urine output.
Nursing Care Plan 4: Imbalanced Nutrition: Less than Body Requirements
Nursing Diagnosis: Imbalanced nutrition: less than body requirements related to malabsorption and nutrient loss through diarrhea.
Goal: The patient will demonstrate improved nutritional status, as evidenced by stable weight and improved laboratory values (e.g., albumin levels).
Interventions:
- Monitor the patient’s weight and nutritional intake daily to detect signs of malnutrition.
- Provide high-calorie, nutrient-dense foods that are easy to digest and absorb, such as soups, broths, and soft foods.
- Collaborate with a dietitian to create a personalized nutrition plan that addresses the patient’s specific needs.
- Administer nutritional supplements (e.g., vitamins and minerals) as needed to compensate for nutrient losses.
Evaluation: The patient’s weight remains stable, and their nutritional status improves as reflected in laboratory results.
Nursing Care Plan 5: Impaired Skin Integrity
Nursing Diagnosis: Impaired skin integrity related to frequent episodes of diarrhea.
Goal: The patient will maintain intact skin without signs of irritation or breakdown.
Nursing Interventions:
- Assess the perianal skin for redness, irritation, or breakdown after each episode of diarrhea.
- Cleanse the skin gently with mild soap and water, and apply barrier creams (e.g., zinc oxide) to protect the skin from irritation.
- Encourage frequent position changes to reduce pressure on vulnerable skin areas.
- Use absorbent pads or diapers to manage stool in incontinent patients while maintaining skin dryness.
- Educate the patient on the importance of skin care and maintaining cleanliness after each episode of diarrhea.
Evaluation: The patient’s skin remains intact with no signs of irritation or breakdown.
