Hypotension, or low blood pressure, occurs when blood pressure readings fall below 90/60 mmHg. While normal blood pressure typically ranges around 120/80 mmHg, hypotension can significantly impact organ perfusion and patient outcomes. Early recognition and appropriate nursing interventions are crucial for preventing complications.
Key Clinical Indicators
- Systolic blood pressure below 90 mmHg
- Diastolic blood pressure below 60 mmHg
- Mean arterial pressure below 65 mmHg
Signs and Symptoms
Patients with hypotension may present with:
- Dizziness or lightheadedness
- Fainting (syncope)
- Blurred vision
- Weakness
- Cold, clammy skin
- Decreased urine output
- Mental confusion
- Rapid, shallow breathing
Common Causes
Several factors can contribute to hypotension:
- Severe blood loss or trauma
- Dehydration
- Severe infections or sepsis
- Cardiac disorders
- Medication side effects
- Endocrine disorders
- Neurological conditions
- Pregnancy
- Orthostatic changes
Nursing Assessment
A thorough nursing assessment includes:
- Vital signs monitoring
- Orthostatic blood pressure measurements
- Cardiovascular assessment
- Neurological status evaluation
- Fluid balance monitoring
- Medication review
- Skin assessment
- Laboratory value analysis
Nursing Care Plans for Hypotension
The following nursing care plans address the most common diagnoses associated with hypotension:
Nursing Care Plan 1. Decreased Cardiac Output
Nursing Diagnosis Statement:
Decreased cardiac output related to reduced preload and blood volume as evidenced by hypotension, tachycardia, and decreased peripheral perfusion.
Related Factors/Causes:
- Hypovolemia
- Reduced venous return
- Medication effects
- Cardiac dysfunction
- Vasodilation
Nursing Interventions and Rationales:
Monitor vital signs every 1-2 hours
- Rationale: Early detection of deterioration
Position patient in Trendelenburg as appropriate
- Rationale: Improves venous return
Administer prescribed IV fluids
- Rationale: Restores blood volume
Monitor urine output
- Rationale: Indicates adequate perfusion
Perform frequent cardiovascular assessments
- Rationale: Identifies changes in cardiac status
Desired Outcomes:
- Blood pressure maintained within normal limits
- Adequate urine output (>0.5 mL/kg/hr)
- Improved peripheral perfusion
- Stable cardiac rhythm
Nursing Care Plan 2. Risk for Falls
Nursing Diagnosis Statement:
Risk for falls related to orthostatic hypotension and altered consciousness.
Related Factors/Causes:
- Postural blood pressure changes
- Dizziness
- Medication side effects
- Weakness
- Altered mental status
Nursing Interventions and Rationales:
Implement fall precautions
- Rationale: Prevents injury
Assist with position changes
- Rationale: Prevents orthostatic hypotension
Keep bed in lowest position
- Rationale: Minimizes injury risk
Maintain clear pathways
- Rationale: Reduces fall hazards
Educate about slow position changes
- Rationale: Prevents sudden blood pressure drops
Desired Outcomes:
- No falls during hospitalization
- Patient demonstrates safe mobility
- Patient verbalizes understanding of fall prevention strategies
Nursing Care Plan 3. Impaired Tissue Perfusion
Nursing Diagnosis Statement:
Impaired tissue perfusion related to decreased cardiac output as evidenced by decreased peripheral pulses and altered mental status.
Related Factors/Causes:
- Reduced cardiac output
- Vasoconstriction
- Blood volume deficits
- Altered blood flow
- Medication effects
Nursing Interventions and Rationales:
Assess peripheral pulses hourly
- Rationale: Monitors tissue perfusion
Monitor skin color and temperature
- Rationale: Indicates peripheral circulation
Perform neurovascular checks
- Rationale: Assesses perfusion status
Administer prescribed vasopressors
- Rationale: Improves tissue perfusion
Monitor oxygen saturation
- Rationale: Ensures adequate oxygenation
Desired Outcomes:
- Improved peripheral perfusion
- Stable vital signs
- Normal skin color and temperature
- Adequate urine output
Nursing Care Plan 4. Deficient Fluid Volume
Nursing Diagnosis Statement:
Deficient fluid volume related to fluid losses as evidenced by hypotension, decreased skin turgor, and concentrated urine.
Related Factors/Causes:
- Active fluid loss
- Inadequate fluid intake
- Hemorrhage
- Excessive diuresis
- Vomiting or diarrhea
Nursing Interventions and Rationales:
Monitor intake and output strictly
- Rationale: Tracks fluid balance
Assess skin turgor and mucous membranes
- Rationale: Indicates hydration status
Administer IV fluids as prescribed
- Rationale: Restores fluid volume
Monitor daily weights
- Rationale: Assesses fluid status
Document fluid losses
- Rationale: Guides replacement needs
Desired Outcomes:
- Improved skin turgor
- Stable vital signs
- Balanced intake and output
- Normal urine specific gravity
Nursing Care Plan 5. Anxiety
Nursing Diagnosis Statement:
Anxiety related to physiological symptoms of hypotension as evidenced by expressed concerns and increased heart rate.
Related Factors/Causes:
- Physical symptoms
- Fear of falling
- Uncertainty about condition
- Limited understanding
- Previous negative experiences
Nursing Interventions and Rationales:
Provide clear explanations
- Rationale: Reduces fear
Teach coping strategies
- Rationale: Improves self-management
Maintain calm environment
- Rationale: Reduces stress
Listen to concerns
- Rationale: Provides emotional support
Include family in education
- Rationale: Enhances support system
Desired Outcomes:
- Decreased anxiety levels
- Improved understanding of the condition
- Enhanced coping mechanisms
- Verbalized comfort with a management plan
Prevention Strategies
- Regular blood pressure monitoring
- Proper hydration
- Medication compliance
- Position changes
- Exercise as appropriate
- Dietary modifications
- Stress management
- Regular medical follow-up
Patient Education
Educate patients about:
- Symptoms requiring medical attention
- Proper blood pressure monitoring
- Medication management
- Lifestyle modifications
- Fall prevention
- When to seek emergency care
- Follow-up care requirements
