Nursing Process
Clostridium difficile infection (CDI), commonly known as C. diff, is caused by a gram-positive, rod-shaped bacterium. Its spores are highly resilient, allowing for easy transmission through contaminated surfaces and person-to-person contact. CDI leads to significant health issues, primarily colitis and diarrhea.
Effective management of CDI involves a multi-faceted nursing approach. Often, CDI is linked to the patient’s current antibiotic regimen. A crucial first step is to identify and discontinue the offending antibiotic, replacing it with an alternative less likely to promote C. difficile overgrowth. Medications such as metronidazole and vancomycin are frequently used, sometimes in combination, to treat CDI, particularly in severe cases. In instances of severe colon damage, surgical intervention may become necessary.
Supportive care is paramount. Adequate nutrition and fluid intake are essential to combat dehydration, a common and serious complication of CDI. Nurses are at the forefront of symptom management, addressing diarrhea, abdominal pain, and associated discomforts. Moreover, nursing education for patients and healthcare staff on strict infection control measures is vital in preventing the spread of C. diff bacteria.
Nursing Assessment
The cornerstone of nursing care begins with a thorough nursing assessment. This involves gathering comprehensive data encompassing the patient’s physical, psychosocial, emotional, and diagnostic status. This section will detail both subjective and objective data collection pertinent to C. difficile infection.
Review of Health History
1. Identify General Symptoms: Diarrhea and colitis are the hallmark indicators of CDI. Severe CDI presents with a constellation of symptoms, including:
- Dehydration: Significant fluid loss due to diarrhea.
- Severe abdominal pain and cramping: Intense discomfort related to colitis.
- Profuse watery diarrhea: Often exceeding ten times daily.
- Nausea: A common gastrointestinal symptom.
- Fever: Indicating an inflammatory response to infection.
- Abdominal distension: Swelling of the abdomen due to inflammation and gas.
- Weight loss: Resulting from fluid loss and reduced appetite.
- Loss of appetite: Anorexia contributing to nutritional deficits.
- Kidney failure: A serious complication of severe dehydration.
- Blood or pus in stool: Indicating severe colitis and potential tissue damage.
2. Evaluate Bowel Habits: Mild to moderate CDI is typically characterized by watery diarrhea occurring more than three times a day for over a day, accompanied by mild abdominal tenderness and cramping.
3. Investigate Potential Transmission Routes: Elicit information from the patient regarding potential exposures to C. difficile through various vectors, such as:
- Foodborne transmission: Contaminated food products.
- Waterborne transmission: Contaminated water sources.
- Environmental contamination: Contact with contaminated soil.
- Fecal-oral route: Transmission via contaminated hands.
- Zoonotic transmission: Contact with human or animal feces.
- Fomite transmission: Contact with dirty surfaces or objects.
4. Conduct Contact Tracing: C. difficile’s highly contagious nature facilitates easy transmission through direct person-to-person contact and contaminated fomites. Asymptomatic carriers, individuals harboring C. difficile without symptoms, can still spread the infection.
5. Determine Risk Factors: While anyone can contract CDI, certain factors elevate the risk:
- Recent antibiotic use: Disrupts normal gut flora, allowing C. difficile to thrive.
- Advanced age (65+ years): Increased susceptibility due to age-related immune changes and comorbidities.
- Recent hospitalization or nursing home admission: Healthcare settings often harbor C. difficile.
- Immunocompromised state: Weakened immune systems are less effective at fighting infection.
- History of CDI: Prior infection increases the risk of recurrence.
- Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease and ulcerative colitis can increase CDI risk.
- Chronic Kidney Disease (CKD): Patients with CKD may have altered gut flora and immune function.
- Recent surgical procedures: Post-operative antibiotic use and hospital stay can increase risk.
6. Review Antibiotic History: Antibiotic use is the leading cause of CDI. Broad-spectrum antibiotics like clindamycin, penicillins, and cephalosporins can disrupt the balance of healthy gut bacteria. This disruption allows C. difficile to proliferate and cause infection.
Physical Assessment
1. Monitor Temperature: Fever is a common systemic response to CDI, indicating infection. A temperature of 100.4°F (38°C) or higher is frequently observed.
2. Observe Stool Characteristics: Frequent, foul-smelling, watery stools are characteristic of CDI. The presence of abdominal cramping and bloody or mucousy diarrhea may suggest pseudomembranous colitis, a more severe form of CDI.
3. Assess Hydration Status: Severe diarrhea in CDI patients significantly increases the risk of dehydration. Monitor for the following signs and symptoms:
- General: Fatigue and weakness.
- Central Nervous System (CNS): Headaches, lightheadedness, and dizziness.
- Head, Eyes, Ears, Nose, Throat (HEENT): Dry mouth and mucous membranes.
- Cardiovascular: Tachycardia (rapid heart rate) and hypotension (low blood pressure).
- Gastrointestinal: Loss of appetite (anorexia), nausea, vomiting, abdominal pain, and abdominal distension.
- Genitourinary: Oliguria (decreased urine output), anuria (absence of urine output), and concentrated urine.
- Integumentary: Dry skin and poor skin turgor (decreased elasticity).
4. Detect Signs of Shock: Severe dehydration from CDI-related diarrhea can lead to serious complications, including shock. Monitor for:
- Altered mental status: Lethargy and confusion.
- Rapid heartbeat.
- Fainting or syncope.
- Electrolyte imbalances.
- Hypotension.
Diagnostic Procedures
1. Stool Specimen Collection: Stool testing is crucial for diagnosing CDI. Testing is recommended for patients experiencing three or more unformed stools of new onset within a 24-hour period without another identified cause. Stools may be positive for blood in severe colitis. Fecal leukocytes (elevated white blood cells) are detected in approximately half of CDI cases.
2. C. difficile Toxin Detection: Stool examination to detect toxigenic C. difficile bacteria or their toxins is the most effective method for CDI diagnosis.
- Enzyme Immunoassay (EIA): A common, rapid test for bacterial toxins. While quicker and easier than older methods, EIA is less sensitive, potentially requiring multiple stool samples for accurate results.
- Polymerase Chain Reaction (PCR): A highly accurate and precise molecular test that detects toxin genes. PCR offers rapid results (within one hour) and requires only a single stool sample.
- Stool Culture: The most sensitive test, but results take several days, potentially delaying diagnosis and treatment initiation.
3. Blood Sample Analysis:
- Complete Blood Count (CBC): May reveal leukocytosis (elevated white blood cell count), indicating infection.
- Electrolyte Panel and Serum Creatinine: Assess hydration status, fluid overload (anasarca), and kidney function.
- Albumin Levels: Hypoalbuminemia (low albumin levels) is likely due to protein loss.
- Serum Lactate Levels: Elevated serum lactate (≥5 mmol/L) indicates severe infection and potential tissue hypoperfusion.
4. Colon Examination (Endoscopy): Imaging is not routinely needed for CDI diagnosis. Sigmoidoscopy (examining the rectum and lower colon) or colonoscopy (examining the entire colon and rectum) can visualize the colon. These procedures can help identify inflammation and rule out other conditions like inflammatory bowel disease.
5. Imaging for Complications: If complications of CDI are suspected, abdominal X-rays or Computed Tomography (CT) scans are indicated. These imaging modalities visualize the colon and can reveal:
- Bowel enlargement or dilation.
- Bowel perforation.
- Increased colon wall thickness, indicating inflammation.
- Toxic megacolon, a life-threatening complication of severe colitis.

Nursing Interventions
Nursing interventions are critical for patient recovery from CDI. This section outlines key nursing interventions for patients with C. difficile infection.
Treat the Infection
1. Discontinue Causative Antibiotic: The initial step in CDI management is stopping the antibiotic that disrupted the gut microbiome and led to C. difficile overgrowth.
2. Initiate CDI-Specific Antibiotics: Ironically, antibiotics are the mainstay treatment for CDI. Oral metronidazole is typically used for mild to moderate CDI, while oral vancomycin or fidaxomicin are preferred for severe cases. Educate patients on the importance of adhering to the prescribed antibiotic regimen. Fidaxomicin is particularly effective in treating recurrent CDI.
3. Administer Antibody-Based Therapy: Bezlotoxumab (Zinplava), a human monoclonal antibody, targets C. difficile toxin B. It is administered to reduce the risk of recurrent CDI in high-risk patients.
4. No Treatment for Asymptomatic Carriers: Asymptomatic patients with positive stool toxin tests do not require antibiotic treatment as they are not clinically ill but can still spread the infection. Focus on strict hygiene and infection control measures.
5. Implement Contact Precautions: Patients with CDI must be placed on strict contact precautions to prevent transmission. Educate patients, families, and visitors about:
- Handwashing with soap and water: Emphasize thorough handwashing after restroom use and before meals or contact with visitors.
- Isolation room: Single-patient room to minimize environmental contamination.
- Dedicated bathroom: Private bathroom for patients with diarrhea to prevent contamination of shared facilities.
- No sharing of personal items: Avoid sharing utensils and personal hygiene items to prevent transmission.
- Bleach disinfection: Cleaning rooms and surfaces with bleach-based disinfectants to kill C. difficile spores.
- Strict adherence to contact precautions: Emphasize consistent hand hygiene and the use of gloves and gowns by healthcare personnel.
- Ineffectiveness of hand sanitizer: Alcohol-based hand sanitizers are not effective against C. difficile spores; soap and water are required.
6. Manage Recurrent Infection: Recurrent CDI is common. Fecal Microbiota Transplantation (FMT) is a highly effective treatment for recurrent CDI. FMT involves restoring healthy gut bacteria by transplanting fecal matter from a healthy donor into the patient’s colon via enema or nasoduodenal tube infusion.
7. Recommend Probiotics: Probiotics, containing beneficial microorganisms, can help restore the balance of gut bacteria and may be recommended as an adjunct therapy to combat C. difficile. However, evidence for their effectiveness in treating active CDI is limited, and they are more often used to prevent CDI recurrence or in conjunction with other treatments.
Manage Diarrhea and Complications
1. Promote Hydration: Diarrhea leads to rapid fluid loss and dehydration. Encourage oral fluid intake as tolerated. Severe dehydration requires intravenous (IV) fluid therapy. Adequate hydration also supports kidney function.
2. Bowel Rest and Dietary Modifications: During acute diarrhea, advise patients to avoid foods that can exacerbate symptoms, such as dairy products (except yogurt with live cultures), fatty foods, high-fiber foods, and spicy or heavily seasoned foods. Recommend bland foods to minimize gastrointestinal upset. The BRAT diet (bananas, rice, applesauce, toast) can be temporarily helpful in reducing diarrhea.
3. Monitor Electrolyte Balance: Diarrhea can cause significant electrolyte losses, especially sodium and potassium. Monitor electrolyte levels and replace as needed. Electrolyte imbalances can be life-threatening.
4. Oral Rehydration Solution (ORS) for Pediatric Patients: For children with diarrhea, ORS, a mixture of water, sugar, and salt, is recommended for rehydration. Zinc supplementation (10-14 day course of dispersible 20 mg zinc tablets) alongside standard care can reduce the duration of diarrhea in children.
5. Perineal Skin Care: Frequent watery diarrhea can cause skin irritation, breakdown, and pressure ulcers in the perineal area. Emphasize meticulous perineal care: keep the area clean and dry, use cool wipes for soothing, and apply barrier creams for incontinent patients.

Nursing Care Plans
Nursing care plans are essential tools for organizing and prioritizing nursing care based on identified nursing diagnoses. They guide assessments and interventions to achieve both short-term and long-term patient goals. Here are examples of nursing care plans for common C. difficile-related nursing diagnoses.
Acute Pain
CDI-related colitis causes abdominal pain, cramping, and inflammation. Frequent diarrhea also leads to perianal discomfort and pain.
Nursing Diagnosis: Acute Pain
Related Factors:
- Diarrhea
- C. difficile infection
- Inflammatory process
- Perineal skin breakdown
As Evidenced By:
- Diaphoresis (sweating)
- Distraction behaviors (e.g., restlessness, moaning)
- Verbal or nonverbal expressions of pain
- Guarding behavior
- Positioning to minimize pain
- Protective behaviors
Expected Outcomes:
- Patient will report pain level of 2/10 or less on a pain scale.
- Patient will report reduced abdominal cramping and tenderness.
- Patient will report relief from perianal discomfort.
Assessments:
1. Pain Assessment: Evaluate pain characteristics (location, intensity, duration, quality, aggravating/relieving factors). Monitor for abdominal distension and swelling, which may indicate worsening condition and complications like toxic megacolon.
2. Pain Relief Measures: Assess the patient’s current pain management strategies (pharmacologic and non-pharmacologic) to evaluate effectiveness and identify additional interventions.
Interventions:
1. Administer Medications as Prescribed: Metronidazole and vancomycin are primary antibiotic treatments for CDI. Nonsteroidal anti-inflammatory drugs (NSAIDs) like naproxen, ibuprofen, and indomethacin are generally contraindicated as they may increase CDI risk. Opioids may also increase the risk of severe disease, complications, prolonged hospital stays, and readmission.
2. Non-Pharmacologic Pain Relief: Educate and encourage the use of non-pharmacologic pain management techniques such as positioning, rest, distraction, breathing exercises, and applying heating pads to the abdomen for comfort.
3. Perineal Comfort Measures: Address perianal pain and irritation from frequent diarrhea with comfort measures such as sitz baths and cooling ointments.
4. Family Involvement: Involve family in care while ensuring infection control precautions. Instruct family on proper hygiene and contact precautions to prevent transmission, but encourage supportive contact to reduce feelings of isolation and pain.
Deficient Fluid Volume
Watery diarrhea in CDI can lead to significant fluid loss and dehydration.
Nursing Diagnosis: Deficient Fluid Volume
Related Factors:
- Diarrhea
- Disease process
- Insufficient fluid intake
- Excessive fluid loss from watery stools
As Evidenced By:
- Altered skin turgor (decreased elasticity)
- Decreased blood pressure
- Dry skin and mucous membranes
- Increased body temperature
- Increased heart rate (tachycardia)
- Increased urine concentration
- Sudden weight loss
- Thirst
- Nausea
- Sunken eyes
- Weakness
Expected Outcomes:
- Patient will maintain adequate hydration, as evidenced by stable vital signs and normal skin turgor.
- Patient will experience no more than two loose stools per day.
- Patient will consume at least 500 mL of oral fluids per day (unless contraindicated).
Assessments:
1. Assess for Dehydration: Monitor for early signs of hypovolemia and dehydration, such as thirst, headache, restlessness, and difficulty concentrating. Closely assess for later signs like poor skin turgor, dry mucous membranes, dizziness, and weakness.
2. Monitor Vital Signs: Track vital signs, particularly blood pressure and heart rate. Hypotension and tachycardia are indicators of fluid volume deficit. Respiratory rate may also increase as the body attempts to compensate.
Interventions:
1. Monitor Fluid Intake and Output (I&O): Accurately measure and record fluid intake and output. Urine output is a sensitive indicator of fluid balance. Decreased urine output and dark, concentrated urine suggest dehydration.
2. Monitor Bowel Movements: Document the frequency and characteristics of bowel movements, including consistency and presence of blood or mucus.
3. Fluid Replacement Therapy: Administer oral or intravenous fluid replacement as prescribed. IV fluids are often necessary to restore circulating volume and correct electrolyte imbalances. Encourage oral intake of water and electrolyte-rich fluids as tolerated.
4. Administer Antibiotics: Administer prescribed antibiotics (metronidazole, vancomycin, fidaxomicin) to treat CDI and reduce diarrhea. While antibiotics initially contributed to CDI, they are essential for treating the infection.
Deficient Knowledge
CDI is highly transmissible, and lack of knowledge about transmission, treatment, and prevention increases the risk of spread and recurrence.
Nursing Diagnosis: Deficient Knowledge
Related Factors:
- Misinformation

Expected Outcomes:
- Patient will demonstrate adherence to infection control measures to prevent C. difficile transmission.
- Patient will not experience CDI recurrence.
Assessments:
1. Assess Health Literacy and Learning Readiness: Evaluate the patient’s health literacy, learning style, needs, and motivation to learn to tailor education effectively.
2. Assess Understanding of CDI: Evaluate the patient’s and family’s understanding of CDI transmission, symptoms, treatment, and prevention to identify knowledge gaps and misconceptions.
Interventions:
1. Educate on Symptoms Requiring Medical Attention: Instruct the patient about symptoms that warrant immediate medical attention, such as persistent watery diarrhea, bloody stools, fever, and vertigo, to facilitate prompt intervention.
2. Educate on Infection Control Measures: Provide detailed education on infection control practices, emphasizing handwashing with soap and water (not just hand sanitizer), especially after using the restroom and before eating.
3. Educate Staff and Visitors: Reinforce contact precautions for all healthcare staff and visitors. Ensure understanding of proper glove and gown use and disposal.
4. Educate on Surgical Treatments (FMT): Explain fecal microbiota transplantation (FMT) as a treatment option for recurrent CDI, clarifying its purpose and procedure if relevant to the patient’s situation.
5. Instruct on Medications for Prevention: Discuss the potential role of probiotics in maintaining gut health and preventing CDI recurrence, if recommended by the healthcare provider.
Diarrhea
Diarrhea is the primary and often debilitating symptom of CDI.
Nursing Diagnosis: Diarrhea
Related Factors:
- Disease process (CDI)
- Inflammatory process (colitis)
- Infection
As Evidenced By:
- Abdominal pain and cramping
- Bowel urgency
- Dehydration
- Hyperactive bowel sounds
- Loose, watery, foul-smelling stools
Expected Outcomes:
- Patient will report reduced abdominal cramping and decreased bowel urgency.
- Patient will report formed, brown stools without a foul odor.
Assessments:
1. Assess Defecation Pattern: Document the frequency, timing, and characteristics of diarrhea episodes. CDI can cause very frequent diarrhea, up to 15 times daily.
2. Assess Stool Characteristics: Describe stool consistency, color, odor, and presence of blood or mucus. CDI stools are typically loose, watery, or semi-formed with a greenish hue and foul odor.
3. Review Stool Culture Results: Monitor stool culture results to confirm CDI diagnosis and guide treatment.
Interventions:
1. Monitor Fluid and Electrolyte Status: Closely monitor intake and output, electrolyte levels, and signs of dehydration (thirst, decreased urine output, dry mucous membranes, lethargy). Track the number of loose stools per day.
2. Encourage Oral Fluid Intake: Promote adequate oral fluid intake, emphasizing fluids containing water, sugar, and salt (e.g., diluted fruit juices, broths) to replace fluid and electrolyte losses.
3. Dietary Modifications: Advise the patient to avoid milk and most dairy products (yogurt with live cultures may be tolerated) as lactose intolerance can worsen diarrhea.
4. Assist with Fecal Microbiota Transplantation (FMT): If FMT is indicated for recurrent CDI, assist with the procedure as per protocol.
5. Administer Antibiotics: Administer prescribed antibiotics (vancomycin, fidaxomicin, metronidazole) to treat CDI and reduce diarrhea.
6. Perineal Hygiene: Provide or assist with meticulous perineal hygiene after each bowel movement to prevent skin irritation and breakdown. Use gentle cleansing and barrier creams as needed.
Imbalanced Nutrition: Less than Body Requirements
CDI-related diarrhea, nausea, and loss of appetite can lead to nutritional deficits.
Nursing Diagnosis: Imbalanced Nutrition: Less than Body Requirements
Related Factors:
