Legionnaire’s Disease Nursing Diagnosis & Care Plan

Legionnaires’ disease is a severe form of pneumonia caused by Legionella bacteria. This nursing diagnosis focuses on the care and management of patients with Legionnaires’ disease, a potentially life-threatening condition that requires prompt and effective nursing interventions.

Causes (Related to)

Legionnaires’ disease is primarily caused by inhaling water droplets containing Legionella bacteria. The following are common risk factors and causes associated with Legionnaires’ disease:

  • Exposure to contaminated water systems (air conditioning systems, cooling towers, hot tubs, large plumbing systems)
  • Age over 50 years
  • Smoking history
  • Chronic lung disease
  • Weakened immune system
  • Recent hospitalization or stay in a long-term care facility
  • Recent travel with exposure to contaminated water sources

Signs and Symptoms (As evidenced by)

Patients with Legionnaires’ disease may present with various signs and symptoms. During a physical assessment, a nurse may observe the following:

Subjective: (Patient reports)

  • High fever (above 104°F or 40°C)
  • Cough (may be dry or produce mucus)
  • Shortness of breath
  • Chest pain
  • Gastrointestinal symptoms (nausea, diarrhea, vomiting)
  • Headache
  • Muscle aches

Objective: (Nurse assesses)

  • Elevated body temperature
  • Increased respiratory rate
  • Decreased oxygen saturation
  • Abnormal lung sounds (crackles, wheezes)
  • Signs of respiratory distress
  • Confusion or altered mental status
  • Abnormal chest X-ray findings
  • Elevated white blood cell count
  • Positive urine antigen test for Legionella pneumophila serogroup 1

Expected Outcomes

The following are common nursing care planning goals and expected outcomes for patients with Legionnaires’ disease:

  • The patient will maintain adequate oxygenation (oxygen saturation > 92% on room air)
  • The patient will demonstrate improved respiratory function and decreased work of breathing
  • The patient will remain afebrile for 24 hours
  • The patient will report reduced chest pain and discomfort

Nursing Assessment

The nursing assessment is crucial in identifying and managing Legionnaires’ disease. The following steps outline the assessment process:

  1. Obtain a detailed patient history
    Focus on recent travel, exposure to potential sources of Legionella bacteria, and presence of risk factors.
  2. Perform a thorough physical examination.
    Assess respiratory rate, work of breathing, use of accessory muscles, and presence of cyanosis.
  3. Auscultate lung sounds
    Listen for crackles, wheezes, or other abnormal breath sounds indicative of pneumonia.
  4. Monitor vital signs
    Pay close attention to temperature, respiratory rate, heart rate, and blood pressure.
  5. Assess oxygen saturation
    Use pulse oximetry to monitor oxygen levels continuously.
  6. Evaluate mental status
    Assess for confusion, disorientation, or other changes in cognitive function.
  7. Review laboratory results
    Check white blood cell count, C-reactive protein, and other inflammatory markers.
  8. Examine chest X-ray findings
    Look for evidence of pneumonia, particularly unilateral infiltrates.
  9. Review urine antigen test results.
    A positive test for Legionella pneumophila serogroup 1 confirms the diagnosis.
  10. Assess hydration status
    Monitor fluid intake, urine output, and signs of dehydration.

Nursing Interventions

Effective nursing interventions are crucial in managing Legionnaires’ disease and promoting patient recovery. The following interventions should be implemented:

  1. Administer oxygen therapy as prescribed
    Provide supplemental oxygen to maintain saturation levels above 92%.
  2. Assist with respiratory treatments.
    Help the patient with prescribed nebulizer treatments or inhalers to improve breathing.
  3. Encourage deep breathing and coughing exercises.
    Teach and assist the patient with techniques to clear secretions and improve lung expansion.
  4. Administer prescribed antibiotics
    Ensure timely administration of appropriate antibiotics, typically fluoroquinolones or macrolides.
  5. Monitor fluid balance
    Encourage oral fluid intake if possible and administer IV fluids as ordered to prevent dehydration.
  6. Implement fever management techniques.
    Administer antipyretics as prescribed and use cooling measures to reduce fever.
  7. Provide positional support
    Assist the patient in maintaining a semi-Fowler’s or high Fowler’s position to ease breathing.
  8. Perform regular oral care
    Maintain good oral hygiene to prevent secondary infections.
  9. Monitor for complications
    Watch for signs of respiratory failure, sepsis, or multiorgan dysfunction.
  10. Educate the patient and family.
    Provide information about Legionnaires’ disease, its treatment, and prevention strategies.

Nursing Care Plans

The following nursing care plans address common problems associated with Legionnaires’ disease:

Care Plan 1: Ineffective Breathing Pattern

Nursing Diagnosis: Ineffective Breathing Pattern related to inflammation and congestion of airways secondary to Legionnaires’ disease

Related factors: Inflammation of lung tissue, accumulation of secretions, fatigue

Nursing Interventions and Rationales:

  1. Assess respiratory rate, depth, and pattern every 2-4 hours
    Rationale: Early detection of changes in respiratory status allows for prompt intervention
  2. Position the patient in semi-Fowler’s or high-Fowler’s position
    Rationale: Promotes optimal lung expansion and eases the work of breathing
  3. Teach and assist with deep breathing and coughing exercises every 2 hours while awake
    Rationale: Helps mobilize secretions and improve ventilation
  4. Administer oxygen therapy as prescribed and monitor oxygen saturation
    Rationale: Ensures adequate oxygenation and prevents hypoxemia
  5. Assist with prescribed respiratory treatments (e.g., nebulizers, inhalers)
    Rationale: Helps reduce airway inflammation and improves breathing

Desired Outcomes:

  • Within 24 hours, the patient will demonstrate improved respiratory rate and depth within normal limits (12-20 breaths/minute).
  • The patient will maintain oxygen saturation > 92% on prescribed oxygen therapy.
  • The patient will report decreased shortness of breath and work of breathing within 48 hours.
  • The patient will demonstrate effective use of deep breathing and coughing techniques.

Care Plan 2: Hyperthermia

Nursing Diagnosis: Hyperthermia related to inflammatory response secondary to Legionnaires’ disease infection
