Sepsis, a life-threatening condition, arises when the body’s response to an infection spirals out of control, triggering widespread inflammation and potential organ dysfunction. Primarily caused by bacterial infections, sepsis can also stem from viral, fungal, or parasitic origins. This systemic infection necessitates prompt recognition and aggressive treatment to avert septic shock, a critical stage that can lead to irreversible organ damage and death.
Characterized by its rapid progression and high mortality rate if not promptly addressed, sepsis disproportionately affects vulnerable populations, including infants, older adults over 65, and individuals with compromised immune systems or pre-existing chronic illnesses. Nurses across all healthcare settings, particularly those in intensive care units (ICUs), play a crucial role in the early detection and management of sepsis. Their vigilance in recognizing subtle signs and symptoms and implementing timely interventions is paramount to improving patient outcomes. Furthermore, proactive infection prevention strategies, encompassing rigorous hand hygiene, adherence to personal protective equipment (PPE) protocols, meticulous wound care, and the consistent application of sterile or aseptic techniques, are essential nursing responsibilities in mitigating sepsis risk.
In this guide, we will delve into the essential aspects of nursing care for patients with sepsis, emphasizing the critical nursing diagnoses, comprehensive assessments, targeted interventions, and evidence-based care plans that are vital for effective management.
The Nursing Process in Sepsis Management
The nursing process serves as a systematic framework for delivering patient-centered care. In the context of sepsis, this process is particularly crucial due to the condition’s complexity and rapid evolution. Nurses must be adept at each stage of the nursing process to ensure optimal patient outcomes.
Comprehensive Nursing Assessment for Sepsis
The cornerstone of effective sepsis management is a thorough nursing assessment. This involves systematically gathering subjective and objective data to gain a holistic understanding of the patient’s condition. A comprehensive assessment encompasses the patient’s health history, physical examination findings, and relevant diagnostic data.
Review of Health History: Uncovering Clues to Sepsis Risk
A detailed review of the patient’s health history is crucial in identifying potential sepsis risk factors and understanding the clinical context. Key aspects to explore include:
-
General Sepsis Symptoms: Document any non-specific symptoms that may indicate sepsis, such as:
- Fluctuations in body temperature (both elevated and decreased)
- Shivering or chills
- Changes in mental status, including confusion or disorientation
- Rapid breathing (tachypnea)
- Skin color changes (flushed or cool)
- Low blood pressure (hypotension)
-
Identifying the Source of Infection: Determine the potential origin of the infection, as sepsis can arise from various sources. Common infection sites include:
- Lungs (pneumonia)
- Urinary tract (kidney, bladder, urinary system infections)
- Gastrointestinal system infections
- Bloodstream infections
- Infections related to invasive devices (catheters, surgical drains)
- Wound or burn infections
-
Sepsis Risk Factors: Identify predisposing factors that increase the patient’s susceptibility to sepsis. These include:
- Age extremes (over 65 years and infancy)
- Compromised immune system (due to conditions like HIV, cancer, or immunosuppressant medications)
- Presence of comorbidities (such as diabetes, chronic kidney disease)
- Prolonged hospitalizations
- Use of invasive lines (central venous catheters, urinary catheters)
- Recent antibiotic use (within 90 days), especially prolonged or unsupervised
- Corticosteroid or other immunosuppressant use
-
Relevant Medical History: Explore pre-existing medical conditions that can elevate sepsis risk:
- Known, undiagnosed, or untreated infections
- Immunocompromising conditions (cancer, HIV)
- Chronic illnesses (diabetes, COPD)
- Recent surgical procedures
- Implanted medical devices (pacemakers, ports)
- Organ transplant complications
-
Medication Review: Document all current medications, paying particular attention to:
- Corticosteroids and other immunosuppressants that can weaken the immune system.
- Antibiotic use history, as factors like inappropriate discontinuation, overuse, or incorrect prescribing can contribute to antibiotic resistance.
Physical Assessment: Recognizing the Clinical Manifestations of Sepsis
A comprehensive physical assessment is crucial for identifying the objective signs of sepsis and monitoring its progression. Key components of the physical assessment include:
-
Vital Signs Assessment: Closely monitor vital signs for early indicators of sepsis:
- Elevated temperature (hyperthermia, >100.4°F or 38°C) or decreased temperature (hypothermia, <96.8°F or 36°C)
- Rapid heart rate (tachycardia, >90 beats per minute)
- Rapid breathing (tachypnea, >20 breaths per minute)

-
Systemic Assessment: Conduct a thorough head-to-toe assessment to identify signs of organ dysfunction, indicating progression towards severe sepsis or septic shock:
- Central Nervous System (CNS): Assess for altered mental status, confusion, lethargy, or decreased responsiveness.
- Respiratory System: Monitor for hypoxia, cough, chest pain, shortness of breath (dyspnea), and increased respiratory effort.
- Cardiovascular System: Assess for decreased capillary refill time (delayed >3 seconds), weak peripheral pulses, and signs of poor perfusion.
- Gastrointestinal System: Evaluate for absent bowel sounds (ileus), abdominal distention, tenderness, or signs of perforation.
- Genitourinary System: Monitor urine output for decreased (oliguria, <30 mL/hour) or absent (anuria) urine production.
- Integumentary System: Observe skin color for flushing, cyanosis, pallor, or mottling, which can indicate circulatory compromise.
-
Assessment for Shock Progression: Recognize the signs of septic shock, indicating a critical stage of sepsis with organ hypoperfusion:
- Cool extremities
- Prolonged capillary refill (>3 seconds)
- Weak, thready pulses
- Pale or clammy skin
- Excessive sweating (diaphoresis)
- Confusion or disorientation
- Decreased level of consciousness
-
Intravenous (IV) Line Inspection: Carefully inspect IV insertion sites for signs of localized infection, such as swelling, redness, pain, or drainage. Central venous catheters are a known risk factor for bloodstream infections and sepsis.
-
Wound and Incision Assessment: Evaluate wounds and surgical incisions for signs of infection, including:

Diagnostic Procedures: Confirming Sepsis and Identifying the Cause
Diagnostic procedures play a crucial role in confirming the diagnosis of sepsis, identifying the causative pathogen, and assessing the extent of organ dysfunction. Common diagnostic tests include:
-
Laboratory Studies: Collect samples for the following laboratory tests:
- Complete Blood Count (CBC): May reveal elevated or decreased white blood cell (WBC) count, low neutrophil count (neutropenia), and low platelet count (thrombocytopenia).
- Kidney Function Tests: Assess kidney function through blood urea nitrogen (BUN) and creatinine levels, which may be elevated due to poor kidney perfusion.
- Blood and Site-Specific Cultures: Obtain cultures from blood, urine, wounds, sputum, or other suspected infection sites to identify the causative organism.
- Urinalysis and Culture: Further investigate urinary tract infections as a potential source of sepsis.
- Biomarkers: Measure biomarkers like procalcitonin and presepsin, which are often elevated in sepsis and can aid in early diagnosis.
- Lactate Levels: Elevated lactate levels (>2 mmol/L) suggest poor tissue perfusion. Levels >4 mmol/L are indicative of septic shock.
- C-Reactive Protein (CRP): Expect elevated CRP levels as an indicator of inflammation.
- Coagulation Studies (INR, PTT): Elevated INR and PTT indicate coagulation abnormalities, which are common in sepsis.
-
Imaging Scans: Prepare the patient for imaging studies to further investigate the source of infection and assess organ involvement. These may include:
- Chest X-ray: To evaluate for pneumonia.
- Chest CT Scan: Provides more detailed imaging of the lungs.
- Abdominal Ultrasound or CT Scan: To assess for intra-abdominal infections.
- Soft Tissue Imaging (Ultrasound, CT, MRI): To evaluate localized infections in soft tissues.
- Brain/Neck CT or MRI (Contrast-Enhanced): May be indicated to rule out central nervous system infections.
-
Invasive Diagnostic Procedures: In certain cases, invasive procedures may be necessary to obtain samples for diagnosis or to drain fluid collections:
- Thoracentesis: To obtain pleural fluid for analysis.
- Paracentesis: To obtain ascitic fluid for analysis.
- Drainage of Fluid Accumulations or Abscesses: To obtain samples and relieve pressure.
- Bronchoscopy with Lavage: To obtain lower respiratory tract samples.
Nursing Interventions for Sepsis Management
Prompt and targeted nursing interventions are crucial for improving patient outcomes in sepsis. These interventions are aimed at addressing the underlying infection, supporting organ function, and preventing complications.
-
Hospital Admission and ICU Preparation: Patients with sepsis typically require admission to an intensive care unit (ICU) for continuous monitoring and aggressive treatment due to the potential for rapid deterioration.
-
Antibiotic Therapy Initiation: Administer broad-spectrum antibiotics intravenously as soon as sepsis is suspected and after obtaining blood cultures. Once culture results are available and the causative pathogen is identified, antibiotics may be narrowed to target the specific organism.
-
Fluid Resuscitation: Initiate aggressive fluid resuscitation with crystalloid solutions (e.g., normal saline, lactated Ringer’s) at a minimum of 30 mL/kg within the first three hours. The goal is to restore intravascular volume and maintain adequate tissue perfusion.
-
Vasopressor Administration: If hypotension persists despite adequate fluid resuscitation, administer vasopressors (e.g., norepinephrine) as prescribed to increase blood pressure and improve organ perfusion.
-
Positioning: Optimize respiratory function through patient positioning. Semi-Fowler’s or high-Fowler’s positions are recommended to reduce the risk of pneumonia. Prone positioning may be considered for patients with sepsis-induced acute respiratory distress syndrome (ARDS).
-
Invasive Monitoring: Prepare for invasive hemodynamic monitoring, such as arterial lines and central venous catheters, to closely track blood pressure, central venous pressure (CVP), and other hemodynamic parameters.
-
Oxygen Therapy and Mechanical Ventilation: Provide supplemental oxygen to patients with hypoxia. Prepare for intubation and mechanical ventilation if respiratory failure develops.
-
Insulin Administration: Manage hyperglycemia, a common occurrence in sepsis, by administering insulin as prescribed for blood glucose levels exceeding 180 mg/dL.
-
Surgical Intervention: Prepare the patient for possible surgical procedures to remove infected or necrotic tissue, which may be the source of sepsis.
-
Intravascular Device Removal: Promptly remove any intravascular access devices (e.g., central lines, peripheral IVs) that are suspected to be the source of infection.
-
Hygiene Practices: Implement meticulous hygiene measures to prevent secondary infections. This includes:
- Strict hand hygiene for healthcare providers, patients, and visitors.
- Regular bed baths for patients.
- Aseptic cleaning of catheters and IV hubs according to hospital protocols.
- Disinfection of all patient care equipment.
-
Transmission-Based Precautions: Implement appropriate infection control precautions, such as contact precautions or droplet precautions, based on the suspected or confirmed pathogen. In some cases, protective isolation may be necessary for immunocompromised patients.
-
Personal Protective Equipment (PPE): Ensure consistent use of appropriate PPE by healthcare staff, including gowns, gloves, masks, and eye protection, to prevent transmission of infection.
-
Nutritional Support: Initiate early enteral nutrition (tube feeding) or parenteral nutrition (IV nutrition) for patients who are unable to eat orally to meet their nutritional needs and support immune function.
Nursing Care Plans for Sepsis: Addressing Key Nursing Diagnoses
Nursing care plans provide a structured approach to organizing and delivering individualized care based on identified nursing diagnoses. In sepsis, several nursing diagnoses are commonly relevant, reflecting the complex physiological and clinical challenges associated with this condition. Here are examples of nursing care plans for key nursing diagnoses in sepsis:
1. Decreased Cardiac Output
Severe sepsis and septic shock can significantly impair cardiac function, leading to decreased cardiac output and compromised tissue perfusion.
Nursing Diagnosis: Decreased Cardiac Output
Related to:
- Altered hemodynamic parameters (hypotension, vasodilation)
- Impaired myocardial contractility (sepsis-induced cardiomyopathy)
- Loss of vascular tone
- Hypovolemia (fluid shifts, capillary leak)
As evidenced by:
- Tachycardia
- Hypotension
- Elevated or decreased Central Venous Pressure (CVP)
- Decreased Mean Arterial Pressure (MAP)
- Cyanosis, pallor
- Prolonged capillary refill time
- Oliguria
- Altered mental status
- Cold, clammy skin
- Diminished peripheral pulses
- Cardiac dysrhythmias
Expected Outcomes:
- Patient will demonstrate adequate cardiac output as evidenced by:
- Vital signs within normal limits (BP, HR, CVP, MAP)
- Urine output of 0.5-1.5 mL/kg/hour
- Absence of cardiac dysrhythmias
- Improved peripheral perfusion (warm extremities, normal capillary refill)
- Stable level of consciousness
Assessments:
- Assess for signs and symptoms of decreased cardiac output: Hypotension, tachycardia, tachypnea, weak pulses, altered mental status.
- Monitor hemodynamic parameters: CVP, MAP, pulmonary artery pressures (if available) to assess fluid status and cardiac function.
- Monitor laboratory data: Cardiac biomarkers (troponin, BNP) may be elevated in sepsis-induced cardiomyopathy. Assess ejection fraction if available.
Interventions:
- Administer fluid resuscitation as prescribed: Crystalloids are the initial fluid choice. Monitor for fluid overload, especially if cardiomyopathy is present.
- Administer medications as prescribed:
- Antibiotics: Timely administration of broad-spectrum antibiotics is crucial.
- Vasopressors: Administer vasopressors (e.g., norepinephrine) to maintain MAP ≥65 mmHg.
- Inotropes: Consider inotropes (e.g., dobutamine) if cardiac output remains low despite fluids and vasopressors.
- Anticipate adjunctive therapies: Mechanical circulatory support (intra-aortic balloon pump, ECMO) may be necessary in severe septic cardiomyopathy.
- Optimize oxygen delivery: Ensure adequate oxygenation to support cardiac function.
2. Hyperthermia
Fever is a common manifestation of sepsis, representing the body’s inflammatory response to infection. However, uncontrolled hyperthermia can be detrimental.
Nursing Diagnosis: Hyperthermia
Related to:
- Infectious process
- Inflammatory response
- Dehydration
- Increased metabolic rate
As evidenced by:
- Elevated body temperature (>100.4°F or 38°C)
- Flushed, warm skin
- Tachypnea
- Tachycardia
- Confusion
- Seizures (in severe cases)
Expected Outcomes:
- Patient will achieve and maintain body temperature within normal limits (97.6°F-99.6°F or 36.4°C-37.6°C).
- Underlying infection will be effectively treated.
- Patient will remain free from complications of hyperthermia.
Assessments:
- Monitor temperature: Rectal temperature is the most accurate for core temperature measurement.
- Assess neurological status: Hyperthermia can affect brain function. Monitor for changes in level of consciousness, confusion, seizures.
Interventions:
- Provide a cool environment: Adjust room temperature, remove excess blankets, and ensure adequate ventilation.
- Apply cooling measures: Cooling blankets, tepid sponge baths, cool compresses to groin and axillae. Avoid inducing shivering, which can increase body temperature.
- Administer antipyretics: Administer acetaminophen or ibuprofen as prescribed to reduce fever.
3. Ineffective Protection
Sepsis compromises the body’s protective mechanisms, increasing vulnerability to further infection and complications.
Nursing Diagnosis: Ineffective Protection
Related to:
- Immunosuppression (sepsis-induced immunodeficiency)
- Infectious process
- Abnormal blood profiles (leukopenia, thrombocytopenia)
- Poor nutritional status
- Medication regimens (immunosuppressants)
- Age extremes
As evidenced by:
- Changes in level of consciousness
- Fatigue, weakness
- Insomnia
- Immobility
- Poor stress management
- Presence of open wounds, pressure ulcers
- Recurrent infections
Expected Outcomes:
- Patient will remain free from secondary infections.
- Patient will demonstrate measures to enhance immune function and protection.
- Patient will verbalize understanding of infection prevention strategies.
Assessments:
- Monitor for signs of infection: Fever, chills, tachycardia, tachypnea, altered mental status, wound drainage, redness.
- Monitor WBC count and differential: Leukocytosis or leukopenia can occur in sepsis. Assess neutrophil count for signs of immune compromise.
- Assess risk factors for ineffective protection: Immunosuppression, chronic illnesses, malnutrition, invasive devices.
Interventions:
- Promote rest and sleep: Adequate rest supports immune function and healing.
- Minimize invasive procedures: Avoid unnecessary catheters, injections, and invasive procedures to reduce infection risk. Use aseptic technique for necessary procedures.
- Promote optimal nutrition: Encourage a high-protein, nutrient-rich diet to support immune function.
- Educate patient and family about infection control: Emphasize hand hygiene, cough etiquette, and avoidance of contact with sick individuals.
4. Risk for Deficient Fluid Volume
Sepsis-induced vasodilation and capillary leak can lead to fluid shifts and hypovolemia, increasing the risk of deficient fluid volume.
Nursing Diagnosis: Risk for Deficient Fluid Volume
Related to:
- Vasodilation
- Increased capillary permeability
- Fluid shifts out of intravascular space
As evidenced by:
A risk diagnosis is not evidenced by signs and symptoms as the problem has not yet occurred. Nursing interventions are aimed at prevention.
Expected Outcome:
- Patient will maintain adequate fluid volume as evidenced by:
- Stable vital signs (BP, HR)
- Adequate urine output (≥0.5 mL/kg/hour)
- Balanced fluid intake and output
- Moist mucous membranes
- Good skin turgor
Assessments:
- Monitor for signs of fluid loss: Hypotension, tachycardia, decreased urine output, dry mucous membranes, poor skin turgor.
- Assess fluid balance: Monitor intake and output, daily weights.
- Monitor for edema: Assess for peripheral edema, which can indicate fluid shifts and third spacing.
- Review laboratory values: Hemoglobin, hematocrit, BUN, creatinine, urine specific gravity.
Interventions:
- Administer IV fluids as prescribed: Crystalloids are the initial choice for resuscitation. Colloids may be used in some cases.
- Administer vasopressors as needed: To support blood pressure if hypotension persists despite fluid resuscitation.
