Weakness Nursing Diagnosis Care Plan: Enhancing Patient Activity and Tolerance

The concept of activity intolerance in nursing, now often referred to as decreased activity tolerance, describes a state where an individual has insufficient physical or psychological energy to perform their desired or necessary daily activities. This condition affects a diverse patient population, ranging from children to older adults, and is particularly prevalent in individuals with a history of reduced activity or previous episodes of intolerance. Understanding the underlying causes, recognizing the signs and symptoms, and implementing effective nursing interventions are crucial for developing a comprehensive care plan.

Delving into the Root Causes of Activity Intolerance

Identifying the factors contributing to activity intolerance is the first step in formulating an effective nursing care plan. Several medical conditions and physiological challenges can lead to this diagnosis:

• Respiratory Conditions: Conditions like Chronic Obstructive Pulmonary Disease (COPD) significantly impact respiratory function, leading to shortness of breath and decreased oxygenation, directly affecting activity tolerance.
• Anemia: A reduction in red blood cells or hemoglobin impairs the body’s ability to transport oxygen, resulting in fatigue and reduced capacity for physical activity.
• Malnutrition: Insufficient nutrient intake deprives the body of the energy and building blocks necessary for muscle function and overall physiological processes, contributing to weakness and activity intolerance.
• Depression: Mental health conditions like depression can cause profound fatigue, loss of motivation, and reduced energy levels, impacting a person’s willingness and ability to engage in activities.
• Pain (Acute or Chronic): Whether sudden or persistent, pain can significantly limit movement and participation in activities. The discomfort and physiological stress associated with pain reduce overall tolerance to exertion.
• Decreased Mobility (Post-Surgical or Injury-Related): Surgical procedures or injuries can lead to prolonged periods of immobility, resulting in muscle weakness and reduced cardiovascular fitness, directly impacting activity tolerance.
• Inadequate Sleep: Sleep deprivation disrupts the body’s restorative processes, leading to fatigue, reduced energy, and impaired physical and cognitive function, all contributing to decreased activity tolerance.
• Cognitive Impairment: Conditions affecting cognitive function can impact a person’s ability to plan, initiate, and safely execute activities, leading to reduced participation and tolerance.
• Generalized Weakness: This broad category encompasses muscle weakness from various causes, including prolonged illness, deconditioning, and certain medical treatments, directly limiting physical endurance.

Recognizing the Signs and Symptoms of Activity Intolerance

Identifying activity intolerance involves recognizing both subjective reports from the patient and objective observations made by the nurse.

Subjective Symptoms (Patient-Reported)

• Patient report of weakness or decreased activity levels: This is a primary indicator, where patients express feeling less active or weaker than usual.
• Shortness of breath with exertion (Dyspnea): Patients may report experiencing breathlessness even with mild activity.
• Fatigue: An overwhelming feeling of tiredness and lack of energy, disproportionate to the activity performed.
• Exertional discomfort: Pain, chest tightness, or general discomfort experienced during or after activity.

Objective Signs (Nurse-Observed)

• Abnormal blood pressure or heart rate response to activity: This includes an exaggerated increase or a drop in blood pressure, or an excessively rapid or irregular heart rate during or after activity.
• Changes in ECG: Electrocardiogram abnormalities that appear or worsen with activity can indicate cardiac stress and intolerance.
• Signs of pain with movement or activity: Observable signs of discomfort like grimacing, guarding, or reluctance to move.
• Difficulty engaging in activity: Observable struggle or inability to initiate or sustain a physical activity.
• Increased oxygen demand: Increased respiratory rate, use of accessory muscles for breathing, or decreased oxygen saturation during activity.

Expected Outcomes: Setting Goals for Improved Activity

The overarching goal of nursing care for activity intolerance is to improve the patient’s ability to participate in activities and enhance their overall quality of life. Expected outcomes include:

• Normalization of vital signs with activity: Patient’s heart rate, blood pressure, and respiratory rate will remain within acceptable limits during and after activity.
• Participation in physical and occupational therapy sessions: Patient will be able to engage in prescribed therapy to improve strength and endurance.
• Return to baseline activity level: Patient will gradually regain their previous level of activity and functional independence.
• Independent completion of Activities of Daily Living (ADLs): Patient will be able to perform self-care tasks such as bathing, dressing, and eating without undue fatigue or distress.
• Stable heart rhythm throughout activity: Patient will maintain a regular heart rhythm without significant arrhythmias during activity.
• Verbalized understanding of gradual activity increase: Patient will demonstrate knowledge of the importance of gradually increasing activity levels and strategies to achieve this safely at home.

Comprehensive Nursing Assessment for Activity Intolerance

A thorough nursing assessment is fundamental to developing an individualized care plan. Key assessment areas include:

1. Current Activity Level and Tolerance: Evaluating the patient’s baseline activity level and their current ability to perform activities is crucial. This provides a starting point for developing a tailored activity plan and tracking progress.

2. Vital Signs Assessment: Establishing baseline vital signs (heart rate, blood pressure, respiratory rate, oxygen saturation) provides a reference point for monitoring physiological responses to activity and identifying any abnormal fluctuations.

3. Identification of Underlying Causes: Determining the root cause of activity intolerance is essential for targeted interventions. This involves reviewing medical history, current conditions, and conducting appropriate physical assessments.

4. Medication Review: Certain medications and their side effects can contribute to fatigue and decreased activity tolerance. Reviewing the patient’s medication list helps identify potential contributing factors and allows for discussions with the healthcare provider about possible adjustments.

5. Nutritional Status Evaluation: Adequate nutrition is vital for energy production and muscle function. Assessing nutritional status ensures that any deficiencies are addressed to support improved activity levels.

6. Need for Assistive Devices: Evaluating the patient’s need for assistive devices (walkers, canes, wheelchairs) can significantly impact their ability to engage in activities. Providing appropriate devices can enhance mobility and safety.

7. Frequent Skin Integrity Assessment: Patients with decreased activity are at increased risk for pressure ulcers. Regular skin assessments are crucial to prevent skin breakdown, especially in immobile or bedridden patients.

Nursing Interventions: Strategies to Enhance Activity Tolerance

Nursing interventions are designed to address the identified causes and symptoms of activity intolerance, promoting gradual improvement and patient empowerment.

1. Range of Motion (ROM) Exercises: For patients with limited mobility, initiating ROM exercises, even in bed, is crucial to maintain joint flexibility and prevent muscle stiffness. Activity should be gradually increased as tolerated.

2. Vital Signs Monitoring During Activity: Closely monitoring vital signs before, during, and after activity ensures patient safety and helps identify any adverse physiological responses that require intervention.

3. Supplemental Oxygen Therapy: Providing supplemental oxygen as needed can alleviate shortness of breath and maintain adequate oxygen saturation levels, enabling patients to participate in activities with less distress.

4. Frequent Position Changes: For patients on bed rest or chair rest, frequent repositioning (every 2 hours or more frequently) is essential to prevent pressure ulcers and promote circulation.

5. Nutritional Support: Addressing any nutritional deficiencies with appropriate supplements or dietary adjustments is vital to provide the body with the necessary fuel for activity.

6. Assistive Device Utilization: Ensuring patients have access to and are properly using necessary assistive devices promotes mobility, safety, and independence in performing activities.

7. Pain Management: Effective pain management, using prescribed analgesics or non-pharmacological methods, is crucial to reduce pain-related limitations to activity. Pain should be addressed proactively, especially before planned activities.

8. Physical Therapy (PT) and Occupational Therapy (OT) Consultation: Consulting with PT and OT professionals is highly beneficial. They can develop individualized exercise programs and strategies to gradually build endurance and improve functional abilities.

9. Emotional Support and Encouragement: Decreased activity can be emotionally challenging. Providing emotional support, encouragement, and positive reinforcement helps patients overcome discouragement and maintain motivation to progress.

10. Patient Education on Safe Activity Increase at Home: Educating patients on how to safely and gradually increase their activity levels at home empowers them to take control of their health and continue progress independently after discharge. This includes teaching them to recognize signs of overexertion and strategies for pacing themselves.

Nursing Care Plans: Examples for Addressing Activity Intolerance

Nursing care plans provide structured frameworks for organizing assessments and interventions. Here are examples of care plans tailored to different underlying causes of activity intolerance:

Care Plan #1: Activity Intolerance related to Generalized Weakness

Diagnostic Statement: Activity intolerance related to generalized weakness as evidenced by verbal reports of fatigue and exertional discomfort.

Expected Outcomes:

• Patient will exhibit stable cardiopulmonary status:
  • Heart rate within normal limits for activity level.
  • Systolic blood pressure increase within 20mmHg over resting BP during activity.
  • Respiratory rate less than 20 breaths per minute.
• Patient will report a Rate of Perceived Exertion (RPE) of 0 or decreased rating after activity.
• Patient will report absence or reduction of fatigue.
• Patient will perform Activities of Daily Living (ADLs) with minimal assistance.

Assessment:

1. Assess precipitating factors: Investigate potential underlying chronic diseases contributing to generalized weakness (e.g., pulmonary disease, anemia, malignancy, hypothyroidism).
2. Monitor cardiopulmonary status:
   • Heart rate and rhythm.
   • Orthostatic blood pressure changes.
   • Respiratory rate and depth.
   • Level of consciousness.
   • Skin color and temperature.

2. Encourage rest periods: Schedule adequate rest periods, especially before meals, ADLs, and planned exercise sessions to allow for energy restoration.
3. Plan activities during peak energy times: Collaborate with the patient to identify times of day when they feel most energetic and schedule activities accordingly.
4. Promote endurance-enhancing physical activity: Encourage activities that build endurance, such as walking, chair exercises, or light resistance training, as tolerated and prescribed by PT/OT.
5. Progress activities gradually:
   • Start with active ROM exercises in bed, progress to sitting and standing.
   • Encourage dangling legs at bedside for 10-15 minutes daily to improve orthostatic tolerance.
   • Implement deep breathing exercises at least three times daily to improve respiratory function.
   • Progress to short walks in the room (1-2 minutes, three times daily), gradually increasing duration and distance.
   • As tolerance improves, progress to walking outside the house.
6. Utilize assistive devices: Provide and encourage the use of assistive devices (transfer chairs, wheelchairs, bath benches, walkers) to reduce fatigue and discomfort during activities.

Care Plan #2: Activity Intolerance related to Compromised Oxygen Transport (Atelectasis)

Diagnostic Statement: Activity Intolerance related to compromised oxygen transport system secondary to atelectasis as evidenced by increased respiratory rate and cyanosis.

Expected Outcomes:

• Patient will not exhibit signs of respiratory distress from atelectasis:

   • Cough (may be present, but not always productive).
   • Sputum production (if present).
   • Dyspnea and increased work of breathing.
   • Tachypnea (rapid breathing).
   • Diminished chest expansion on the affected side.
   • Cyanosis (bluish discoloration of skin and mucous membranes).
2. Monitor laboratory and diagnostic findings:
   • Chest X-ray results (tracheal shift, pulmonary opacities).
   • Arterial Blood Gases (ABGs) (hypoxemia, respiratory alkalosis).
   • Chest CT scan (lung densities, volume reduction).

Interventions:

1. Administer medications as prescribed:
   • Mucolytics (e.g., acetylcysteine) to help clear airway mucus.
   • Bronchodilators to open airways (if prescribed for underlying condition).
   • Antibiotics if atelectasis is due to infection.
2. Encourage deep breathing and incentive spirometry: Instruct and assist patient with deep breathing exercises and use of incentive spirometry to promote lung expansion and prevent further collapse.
3. Teach energy conservation techniques:
   • Change positions frequently to improve lung expansion and reduce fatigue.
   • Push rather than pull objects to reduce exertion.
   • Sit down to perform tasks whenever possible.
   • Rest for at least one hour after meals before engaging in activities.
   • Organize daily activities with work-rest-work schedules.
4. Refer to respiratory therapy for pulmonary rehabilitation: Pulmonary rehabilitation programs offer comprehensive strategies to improve respiratory function, exercise tolerance, and quality of life.
5. Provide supplemental oxygen: Administer oxygen therapy as prescribed to maintain SpO2 above 90% and improve oxygen delivery to tissues.

Care Plan #3: Activity Intolerance related to Physical Deconditioning/Immobility

Diagnostic Statement: Activity intolerance related to physical deconditioning or immobility as evidenced by dyspnea on exertion and abnormal heart rate or blood pressure response to activity.

Expected Outcomes:

• Patient will demonstrate increased tolerance to activity over time.
• Patient will participate in prescribed physical activity with appropriate physiological responses:
  • Heart rate, blood pressure, and respiratory rate within acceptable limits for activity level.

Assessment:

1. Assess level of physical activity and mobility: Determine the patient’s current functional capacity and the level of assistance required for mobility and activity. Use standardized assessment tools if available.
2. Determine cause of activity intolerance: Differentiate between physical deconditioning, psychological factors (fear, anxiety), or motivational issues contributing to reduced activity.
3. Monitor and record activity tolerance: Assess vital signs (pulse rate, blood pressure, respiratory pattern, oxygen saturation) before, during, and after activity. Observe for signs and symptoms of cardiac decompensation (dyspnea, palpitations, chest discomfort, hypotension/hypertension, tachycardia, decreased SpO2, lightheadedness), which indicate the need to stop activity immediately.

Interventions:

1. Position upright if bed rest is required: Elevate the head of the bed or position the patient in a chair to minimize cardiovascular deconditioning associated with prolonged bed rest.
2. Assist with self-care and gradually increase activity: Provide assistance with ADLs, positioning, and transfers. Progress activity gradually from sitting in bed to dangling legs, standing, and ambulating, as tolerated. Always assess for orthostatic hypotension before standing.
3. Perform Range of Motion (ROM) exercises: If the patient is immobile, perform passive or active-assisted ROM exercises to maintain joint mobility, muscle tone, and circulation.
4. Refer to physical therapy: Consult with physical therapy for a comprehensive evaluation and development of an individualized activity plan to improve strength, endurance, and mobility.
5. Provide emotional support and encouragement: Address patient fears and anxieties related to activity (breathlessness, pain, falls). Provide positive reinforcement and set mutual, achievable goals to progressively increase activity levels.
6. Obtain necessary assistive devices: Ensure availability and proper use of assistive devices (walkers, canes, crutches, portable oxygen) to support safe ambulation and increased activity levels.
