Peripheral Arterial Disease (PAD), often referred to as Peripheral Vascular Disease (PVD), is a common circulatory problem in which narrowed arteries reduce blood flow to the limbs. Understanding PAD and its associated nursing diagnoses is crucial for providing effective patient care and improving outcomes. This article delves into the essential aspects of nursing diagnoses related to PAD, offering a comprehensive guide for healthcare professionals.
Nursing Process for Peripheral Arterial Disease
Managing Peripheral Arterial Disease effectively centers around minimizing the risk of cardiovascular complications and addressing the chronic conditions that contribute to blood vessel damage. Nurses are pivotal in promoting health by educating patients and encouraging them to adopt lifestyle modifications and adhere to prescribed medication regimens.
In situations where lifestyle adjustments, exercise, and medication are insufficient to alleviate PAD symptoms, revascularization procedures like bypass grafting or angioplasty may be necessary. Nurses are indispensable in delivering both pre- and post-operative care to mitigate complications and facilitate patient recovery.
Comprehensive Nursing Assessment for PAD
The cornerstone of nursing care begins with a thorough nursing assessment. This involves gathering comprehensive data – physical, psychosocial, emotional, and diagnostic – to understand the patient’s condition fully. Here, we explore both subjective and objective data collection relevant to PAD.
Detailed Review of Health History
1. Identifying General Symptoms: Recognize and document the broad spectrum of symptoms associated with PAD:
- General Indicators:
- Exacerbated pain during physical activity.
- Cardiovascular Manifestations:
- Weak or absent peripheral pulses in the extremities.
- Integumentary Changes:
- Variations in skin coloration (pallor, cyanosis, or erythema).
- Reduced skin temperature, particularly in the affected limbs.
- Skin on lower extremities becoming thin, taut, and shiny.
- Development of gangrenous tissue.
- Noticeable hair loss or thinning on the legs.
- Presence of slow-healing wounds and ulcers.
- Thickening and opacity of toenails.
- Reproductive Issues:
- Reports of impotence.
- Musculoskeletal Symptoms:
- Decreased mobility.
- General muscle weakness.
- Sensation of heaviness in the muscles.
- Numbness and tingling (paresthesia).
- Intermittent claudication: muscle pain during activity that subsides with rest.
2. In-depth Medical History Review: Atherosclerosis is the primary underlying cause of PAD. It’s essential to identify pre-existing conditions that contribute to plaque formation:
3. Detailed Family History: A significant family history of PAD includes at least one first-degree relative who required revascularization or stent placement for PAD before the age of 65. Document any family history of stroke or heart disease as well.
4. Risk Factor Identification: Note the following key risk factors that predispose individuals to PAD:
- Smoking history.
- Sedentary lifestyle.
- Male gender.
- Advanced age.
- Obesity.
- African-American ethnicity.
5. Current Dietary Assessment: Diet significantly impacts plaque buildup in arteries, directly contributing to PAD. Identify dietary habits that promote plaque formation:
- High intake of saturated fats (fatty foods).
- Consumption of simple carbohydrates (high sugar content).
- Diet rich in sodium.
Physical Examination for PAD
1. Assessing the 5 P’s: PAD is classically associated with the “5 P’s,” critical indicators requiring immediate attention:
- Pulselessness: Absence of palpable pulse.
- Paralysis: Inability to move the affected limb.
- Paresthesia: Abnormal sensation like tingling or numbness.
- Pain: Limb pain, especially at rest or with elevation.
- Pallor: Paleness of the skin.
Note: Paresthesia and paralysis are critical signs of ischemia and potential limb loss, demanding immediate assessment and specialist consultation.
2. Cardiovascular Status Evaluation: Auscultate the heart to detect murmurs or irregularities. Palpate peripheral pulses in all extremities, assessing for bruits and pulse quality.
3. Allen Test Administration: Perform the Allen test to evaluate the patency of the radial and ulnar arteries and assess collateral blood flow to the hand. A negative Allen test suggests insufficient dual blood supply to the hand.
4. Skin Condition Assessment: Observe for skin changes indicative of PAD:
- Alopecia (hair loss on the extremities).
- Skin that is dry, scaly, or erythematous.
- Persistent pigment changes.
- Brittle nails.
5. Advanced PAD Symptom Recognition: Identify symptoms suggestive of advanced PAD:
- Pulselessness.
- Numbness.
- Cyanosis.
- Livedo reticularis: Mottling with a “fishnet pattern”.
- Cold extremities.
- Paralysis.
- Gangrene.
- Non-healing wounds and ulcers.
6. Pain Evaluation: Characterize pain, especially intermittent claudication – pain induced by walking and relieved by rest. Pain at rest is a more serious sign of ischemia.
Diagnostic Procedures for PAD
1. Blood Tests: Routine blood tests are essential to assess organ function and identify vascular disease risk factors:
- Complete blood count (CBC).
- Blood urea nitrogen (BUN).
- Creatinine levels.
- Electrolyte levels.
To evaluate vascular disease risk, specific tests include:
- Coagulation tests.
- Lipid profiles.
2. Inflammatory Marker Analysis: Elevated inflammatory markers are linked to exercise intolerance in PAD:
- D-dimer.
- C-reactive protein.
- Interleukin-6.
- Homocysteine.
3. Ankle-Brachial Index (ABI) Measurement: ABI is a crucial non-invasive test comparing blood pressures in the lower and upper extremities. Lower extremities typically have slightly higher blood pressure.
4. Doppler Ultrasound Preparation: Doppler ultrasound is a primary non-invasive method to assess blood flow. Absent or faint sounds indicate blockage or reduced flow.
5. Transcutaneous Oximetry Consideration: Transcutaneous oximetry assesses blood flow impairment, increasingly used in diabetic patients and wound care.
6. Imaging Scans Anticipation: Advanced imaging provides detailed visualization of blood vessels:
- Magnetic Resonance Imaging (MRI): Offers high detail for plaque visualization.
- Computed Tomography (CT) with contrast: Useful for visualizing arterial insufficiency.
- CT Angiography (CTA): Provides rapid, non-invasive results.
- Magnetic Resonance Angiography (MRA): Highly accurate without radiation but can be costly and less accessible.

Nursing Interventions for PAD
Effective nursing interventions are vital for patient recovery and managing PAD progression.
1. Disease Progression Prevention: Lifestyle modification is the first step to halt PAD progression. Pharmacological and endovascular treatments may be needed to manage symptoms and reduce cardiovascular risks.
2. Medication Administration: Manage underlying conditions with prescribed medications:
- Statins: Lower LDL (bad cholesterol) and increase HDL (good cholesterol) to prevent plaque buildup, reducing stroke and heart attack risk.
- Antihypertensive Drugs: Maintain blood pressure within normal limits.
- Antidiabetic Agents: Control blood sugar levels.
- Antiplatelets & Anticoagulants: Prevent blood clot formation (e.g., clopidogrel, warfarin).
- Cilostazol: Vasodilator and antiplatelet to widen vessels and improve limb blood flow, relieving leg pain.
3. Comorbidity Management: Aim for blood pressure below 120/80 mmHg (non-diabetic) or 130/80 mmHg (diabetic). Achieve HbA1c under 7% for diabetic patients.
4. Revascularization Preparation: For severe symptoms unresponsive to treatment, prepare patients for:
- Endovascular intervention.
- Surgical procedures (angioplasty, stent placement, bypass surgery).
- Combined interventions.
5. Exercise Promotion: Exercise therapy significantly reduces claudication symptoms. Refer to physical therapy as needed.
6. Blood Clot Treatment: Address thrombi or emboli with immediate heparin infusion to achieve an activated partial thromboplastin time 1.5 times normal.
7. Lifestyle Modification Encouragement: Educate patients on:
- Regular physical activity.
- Weight management.
- Heart-healthy diet.
- Smoking cessation.
- Medication adherence.
8. Pseudoephedrine Avoidance: Advise against cold/sinus drugs containing pseudoephedrine (e.g., Sudafed) as they narrow blood vessels, potentially worsening PAD symptoms.
9. Nutritionist Referral: Emphasize a heart-healthy, low-fat, low-sodium, and low-processed food diet.
10. Foot Care Education: Educate on proper foot care due to increased risk of poor wound healing, especially in diabetic patients. Lack of blood flow delays healing and increases infection risk.
Nursing Care Plans for PAD
Nursing care plans are crucial for prioritizing assessments and interventions based on identified nursing diagnoses for PAD, guiding both short-term and long-term care goals.
Acute Pain Nursing Diagnosis for PAD
Acute pain is a frequent symptom in PAD, typically occurring during walking distal to the arterial blockage, described as cramping or aching. Often undertreated because it’s relieved by rest, leading to delayed diagnosis.
Nursing Diagnosis: Acute Pain
Related Factors:
- Vascular system blockage.
- Peripheral vascular disease.
Evidenced By:
- Expressing pain, cramping, or aching during walking.
- Burning foot pain (severe cases).
- Muscle fatigue.
- Avoiding physical activity due to pain.
Expected Outcomes:
- Patient reports reduced pain during walking.
- Patient increases physical activity without pain.
Nursing Assessments for Acute Pain:
1. Pain Characteristic Assessment: Detailed pain assessment aids in diagnosing PAD. In severe PAD, rest pain may occur, described as burning foot pain, worse at night, relieved by dangling feet.
2. Prior Pain Relief Efforts: Assess previous pain relief methods and their outcomes to tailor interventions and aid diagnosis.
Nursing Interventions for Acute Pain:
1. Medication Administration: Administer prescribed medications. Cilostazol, a vasodilator, can treat claudication, taking up to 12 weeks for effect.
2. Exercise Encouragement: Despite pain, exercise is vital. Instruct patients to walk until pain onset, rest, and resume. Sessions should be 30-45 minutes, 3-4 times weekly.
3. Lifestyle Modification Education: Managing PAD and pain requires healthy weight, exercise, and chronic condition management.
4. Avoid Massaging Affected Extremities: Massaging may dislodge emboli. Advise consulting a doctor before massage.
Chronic Pain Nursing Diagnosis for PAD
PAD causes chronic pain, including intermittent claudication, ischemic pain, and neuropathic pain.
Nursing Diagnosis: Chronic Pain
Related Factors:
- Limb ischemia.
- Atherosclerosis (plaque buildup).
- Severe claudication.
- Sedentary lifestyle.
- Obesity.
Evidenced By:
- Burning pain.
- Paresthesias.
- Intermittent claudication.
- Altered mobility.
Expected Outcomes:
- Patient reports decreased burning, tingling, and numbness.
- Patient uses non-pharmacological pain management methods.
Nursing Assessments for Chronic Pain:
1. Pain Characteristic Assessment: Burning, tingling, stabbing pain, and reduced sensation are common. Pain worsens with activity, improves with rest. Worsening pain indicates disease progression.
2. Chronic Critical Limb Ischemia Signs: Assess for signs of limb-threatening ischemia:
- Rest pain.
- Recumbent pain.
- Ischemic skin lesions (ulcers, gangrene).
- ABI of 0.4 or less.
3. Phantom Limb Pain Assessment: If amputation is considered, assess for risk factors for phantom limb pain, common in amputees, especially with high pre- and post-operative pain levels.
Nursing Interventions for Chronic Pain:
1. Prioritize Exercise: Exercise therapy is recommended early for intermittent claudication. Collaborate with PT/OT for exercise plans and safety adaptations.
2. Psychological Techniques: Consider biofeedback, mirror therapy, imagery, and meditation alongside medications.
3. Spinal Cord Stimulation Discussion: For severe ischemic pain unresponsive to analgesics, spinal cord stimulation can mask pain via electrical pulses to nerves.
4. Chronic Pain Coping Support: Address the impact of chronic pain on sleep, appetite, social interaction, and mood. Offer mental health support services.
5. Surgical Intervention Preparation: Revascularization treatments restore blood flow and relieve pain in PAD.
Ineffective Peripheral Tissue Perfusion Nursing Diagnosis for PAD
PAD impairs peripheral tissue perfusion due to atherosclerotic plaque, blocking arteries and reducing circulation.
Nursing Diagnosis: Ineffective Peripheral Tissue Perfusion
Related Factors:
- Disease process.
- Atherosclerotic plaque buildup.
- Reduced blood flow.
Evidenced By:
- Absent/weak peripheral pulses.
- Muscle weakness and fatigue.
- Cool, cyanotic skin.
- Shiny, hairless legs.
- Decreased extremity blood pressure.
- Delayed wound healing.
- Edema.
- Extremity pain.
- Femoral bruit.
- Intermittent claudication.
- Paresthesia.
- Pallor with limb elevation.
Expected Outcomes:
- Patient demonstrates adequate tissue perfusion (3+ peripheral pulses).
- Patient verbalizes medication regimen for PAD management.
Nursing Assessments for Ineffective Tissue Perfusion:
1. Peripheral Pulse Assessment: Reduced or absent pulses indicate arterial insufficiency, potentially leading to ischemia and necrosis.
2. Ankle-Brachial Index (ABI) Assessment: ABI <0.9 indicates PAD.
Nursing Interventions for Ineffective Tissue Perfusion:
1. Chronic Condition Management: Manage comorbidities like atherosclerosis, diabetes, and hypertension to prevent complications. Ensure treatment plan adherence.
2. Avoid Prolonged Sitting: Encourage ambulation to improve venous return and avoid prolonged sitting.
3. Statin Consideration: Statins and lifestyle changes improve atherosclerosis and PAD.
4. Surgical Intervention Preparation: Prepare for revascularization procedures (angioplasty, stent, bypass) in severe cases.

Risk for Injury Nursing Diagnosis for PAD
PAD increases injury risk due to impaired physical function, risk of falls, trauma, and skin breakdown.
Nursing Diagnosis: Risk for Injury
Related Factors:
- Disease process.
- Tissue hypoxia.
- Altered peripheral sensation.
- Decreased lower extremity strength.
- Impaired balance.
Evidenced By:
(Risk diagnosis – no evidence by signs/symptoms; interventions are preventative.)
Expected Outcomes:
- Patient remains free of injury.
- Patient demonstrates two fall and injury prevention strategies.
Nursing Assessments for Risk for Injury:
1. Environmental and Self-Care Assessment: Assess living environment, safety risks (stairs), and self-care abilities, especially in older adults.
2. Mobility Issue Assessment: Determine functional ability and plan fall prevention strategies.
Nursing Interventions for Risk for Injury:
1. Fall Prevention During Walking: Provide assistive devices (cane, walker) for exercise programs if balance or strength is poor.
2. Foot Care Instruction: Educate on proper footwear and daily foot/leg inspection, especially with diabetes.
3. Smoking Cessation: Smoking is a major risk for limb ischemia and amputation. Support smoking cessation programs.
4. PT/OT Referral: Refer to physical and occupational therapy to ensure a safe living environment and appropriate exercise programs.
Risk for Peripheral Neurovascular Dysfunction Nursing Diagnosis for PAD
PAD narrows blood vessels outside the heart, compromising blood flow to extremities, especially legs, increasing risk for neurovascular dysfunction.
Nursing Diagnosis: Risk for Peripheral Neurovascular Dysfunction
Related Factors:
- Atherosclerosis (plaque buildup).
- Reduced blood flow to extremities.
- Sedentary lifestyle.
Evidenced By:
(Risk diagnosis – no evidence by signs/symptoms; interventions are preventative.)
Expected Outcomes:
- Patient does not display decreased peripheral pulses or pallor.
- Patient does not report paresthesia.
Nursing Assessments for Risk for Peripheral Neurovascular Dysfunction:
1. Neurovascular Status Assessment: Check pulse strength, skin color/temperature, capillary refill, sensation, and muscle strength, comparing sides.
2. Balance and Gait Monitoring: Assess balance and gait abnormalities. PAD patients may have irregular gait with shorter steps.
3. 5 P’s Assessment: Monitor for signs of reduced blood flow: Pain, Paralysis, Paresthesia, Pulselessness, Pallor.
Nursing Interventions for Risk for Peripheral Neurovascular Dysfunction:
1. Positioning Instructions: Avoid leg crossing to prevent blood flow interference. Elevate legs (not above heart level, as extreme elevation slows arterial flow).
2. Medication Administration: Administer medications to manage conditions and ensure blood flow: Antihypertensives, Statins, Antiplatelets/Anticoagulants.
3. Supervised Exercise Program Enrollment: Enroll in monitored exercise programs (treadmill walking 3x/week) to improve circulation and prevent dysfunction.
4. Neurovascular Dysfunction Sign Education: Educate on signs requiring immediate attention: burning foot pain, paresthesia, diminished pulses, pale/cyanotic extremities, cool skin, prolonged capillary refill, decreased sensation/motor function.
5. Image Documentation: With consent, document PAD progression with clinical images of skin changes, hair loss, nail abnormalities.
