Peripheral Arterial Disease (PAD) represents a significant cardiovascular condition requiring comprehensive nursing assessment and care planning. This progressive disorder affects the peripheral arteries, primarily those supplying blood to the legs and feet, and demands thorough understanding for optimal patient outcomes.
Pathophysiology and Clinical Manifestations
PAD occurs when atherosclerotic plaques accumulate in the peripheral arteries, leading to reduced blood flow to the extremities. This restriction in blood flow results in tissue ischemia and various clinical manifestations that nurses must recognize and address through appropriate nursing diagnoses and interventions.
Clinical Manifestations:
- Intermittent claudication
- Rest pain in affected limbs
- Diminished or absent peripheral pulses
- Skin changes (coolness, pallor, or cyanosis)
- Delayed wound healing
- Hair loss on affected limbs
- Muscle atrophy
- Trophic changes in nails
Comprehensive Nursing Assessment
Physical Assessment
Cardiovascular Assessment:
- Evaluate peripheral pulses
- Assess capillary refill
- Monitor skin temperature and color
- Check for edema
Pain Assessment:
- Character and intensity of pain
- Aggravating and alleviating factors
- Impact on daily activities
- Rest pain presence
Functional Assessment:
- Walking distance capability
- Activity limitations
- Independence in ADLs
- Balance and gait evaluation
Diagnostic Indicators
Ankle-Brachial Index (ABI):
- Normal: 1.0-1.4
- Mild PAD: 0.9-0.7
- Moderate PAD: 0.69-0.4
- Severe PAD: <0.4
Additional Tests:
- Doppler ultrasound
- Arteriography
- CT angiography
- MR angiography
Nursing Care Plans for Peripheral Arterial Disease
1. Decreased Peripheral Tissue Perfusion
Nursing Diagnosis Statement:
Decreased peripheral tissue perfusion related to arterial insufficiency secondary to atherosclerotic disease process.
Related Factors:
- Atherosclerotic changes in peripheral vessels
- Reduced arterial blood flow
- Endothelial damage
- Inflammatory processes
Nursing Interventions and Rationales:
- Assess peripheral pulses q4h
Rationale: Early detection of circulatory changes - Monitor skin color, temperature, and capillary refill
Rationale: Indicators of tissue perfusion status - Position affected limb(s) in a dependent position
Rationale: Promotes gravitational blood flow - Administer prescribed medications
Rationale: Improves blood flow and reduces symptoms
Desired Outcomes:
- Maintain adequate tissue perfusion
- Demonstrate improved peripheral pulses
- Show normal skin color and temperature
- Report decreased pain levels
2. Activity Intolerance
Nursing Diagnosis Statement:
Activity intolerance related to imbalance between oxygen supply and demand secondary to peripheral arterial insufficiency.
Related Factors:
- Decreased peripheral circulation
- Muscle weakness
- Pain with activity
- Sedentary lifestyle
Nursing Interventions and Rationales:
- Implement a graduated exercise program
Rationale: Builds exercise tolerance safely - Monitor vital signs during activity
Rationale: Ensures safe activity levels - Teach energy conservation techniques
Rationale: Maximizes activity effectiveness - Schedule rest periods
Rationale: Prevents overexertion
Desired Outcomes:
- Increase activity tolerance
- Maintain stable vital signs during activity
- Demonstrate appropriate use of energy conservation techniques
- Report decreased claudication pain
3. Risk for Impaired Skin Integrity
Nursing Diagnosis Statement:
Risk for impaired skin integrity related to compromised peripheral circulation.
Related Factors:
- Decreased peripheral blood flow
- Impaired sensation
- Poor tissue oxygenation
- Altered metabolic state
Nursing Interventions and Rationales:
- Perform daily skin assessment
Rationale: Early detection of skin breakdown - Implement pressure relief measures
Rationale: Prevents tissue damage - Maintain proper skin hygiene
Rationale: Promotes skin integrity - Teach proper foot care
Rationale: Prevents complications
Desired Outcomes:
- Maintain intact skin
- Demonstrate proper skin care techniques
- Identify early signs of skin breakdown
- Implement preventive measures
4. Chronic Pain
Nursing Diagnosis Statement:
Chronic pain related to tissue ischemia secondary to peripheral arterial disease.
Related Factors:
- Tissue hypoxia
- Nerve compression
- Inflammatory process
- Altered blood flow
Nursing Interventions and Rationales:
- Assess pain characteristics regularly
Rationale: Guides pain management strategies - Administer prescribed pain medications
Rationale: Controls pain symptoms - Teach non-pharmacological pain management
Rationale: Provides additional pain relief methods - Monitor pain impact on daily activities
Rationale: Evaluates treatment effectiveness
Desired Outcomes:
- Report decreased pain levels
- Demonstrate effective pain management strategies
- Maintain daily activities despite pain
- Show improved quality of life
5. Knowledge Deficit
Nursing Diagnosis Statement:
Knowledge deficit related to lack of information about disease process and management strategies.
Related Factors:
- Limited exposure to information
- Misinterpretation of information
- Lack of resources
- Complex medical terminology
Nursing Interventions and Rationales:
- Provide disease education
Rationale: Increases understanding of the condition - Teach medication management
Rationale: Ensures proper treatment adherence - Demonstrate lifestyle modifications
Rationale: Promotes self-management skills - Review risk factor modification
Rationale: Prevents disease progression
Desired Outcomes:
- Demonstrate an understanding of the disease process
- Show proper medication management
- Implement lifestyle modifications
- Identify risk factors and prevention strategies
