Functional ability refers to an individual’s capacity to perform activities of daily living (ADLs) and maintain independence. This nursing diagnosis focuses on assessing, maintaining, and improving a patient’s functional capabilities while preventing complications from functional decline.
Causes (Related to)
Functional ability can be impacted by various factors that affect a person’s capacity to perform daily activities:
- Physical conditions including:
- Musculoskeletal disorders
- Neurological conditions
- Chronic pain
- Post-surgical recovery
- Cardiovascular diseases
- Age-related factors such as:
- Decreased muscle strength
- Reduced balance
- Impaired coordination
- Cognitive decline
- Environmental factors including:
- Lack of assistive devices
- Unsafe home environment
- Limited access to resources
- Social isolation
Signs and Symptoms (As evidenced by)
Functional ability impairment presents various indicators that nurses must recognize for accurate assessment and intervention.
Subjective: (Patient reports)
- Difficulty performing self-care activities
- Decreased energy levels
- Fear of falling
- Pain during movement
- Feelings of dependence
- Frustration with limitations
- Loss of confidence
Objective: (Nurse assesses)
- Impaired mobility
- Decreased muscle strength
- Poor balance
- Unsteady gait
- Difficulty with transfers
- Reduced range of motion
- Decreased endurance
- Need for assistance with ADLs
Expected Outcomes
The following outcomes indicate successful management of functional ability:
- The patient will demonstrate improved independence in ADLs
- The patient will maintain or improve current functional status
- The patient will use assistive devices correctly
- The patient will perform exercises as prescribed
- The patient will maintain safety during activities
- The patient will report increased confidence in performing tasks
- The patient will achieve an optimal level of function within the limitations
Nursing Assessment
Evaluate Physical Function

- Evaluate muscle strength
- Check the range of motion
- Monitor balance and coordination
- Observe gait pattern
- Assess transfer ability
- Document activity tolerance
Review ADL Performance
- Evaluate self-care capabilities
- Assess feeding ability
- Monitor hygiene practices
- Check dressing skills
- Observe toileting independence
- Document bathing ability
- Assess grooming skills
Assess Safety Factors
- Check for fall risks
- Evaluate home environment
- Review medication effects
- Assess cognitive status
- Monitor vision and hearing
- Document safety awareness
- Evaluate the need for assistive devices
Nursing Care Plans
Nursing Care Plan 1: Impaired Physical Mobility
Nursing Diagnosis Statement:
Impaired Physical Mobility related to decreased muscle strength and endurance as evidenced by difficulty with ambulation and transfers.
Related Factors:
- Musculoskeletal impairment
- Reduced muscle strength
- Decreased endurance
- Pain with movement
- Fear of falling
Nursing Interventions and Rationales:
- Assess current mobility status
Rationale: Establishes baseline and identifies specific limitations - Implement a progressive mobility program
Rationale: Gradually improves strength and endurance - Teach proper use of assistive devices
Rationale: Ensures safe mobility and prevents falls
Desired Outcomes:
- The patient will demonstrate improved mobility
- The patient will use assistive devices correctly
- The patient will maintain safety during movement
Nursing Care Plan 2: Self-Care Deficit
Nursing Diagnosis Statement:
Self-Care Deficit related to functional limitations as evidenced by the inability to perform ADLs independently.
Related Factors:
- Physical limitations
- Fatigue
- Pain
- Cognitive impairment
- Lack of motivation
Nursing Interventions and Rationales:
- Assess the level of independence in ADLs
Rationale: Identifies specific areas needing assistance - Provide adaptive equipment
Rationale: Promotes independence in self-care activities - Teach energy conservation techniques
Rationale: Maximizes ability to perform tasks independently
Desired Outcomes:
- The patient will demonstrate increased independence in ADLs
- The patient will utilize adaptive equipment effectively
- The patient will report improved confidence in self-care activities
Nursing Care Plan 3: Risk for Falls
Nursing Diagnosis Statement:
Risk for Falls related to impaired balance and mobility as evidenced by unsteady gait and history of falls.
Related Factors:
- Impaired balance
- Muscle weakness
- Environmental hazards
- Medication effects
- Visual impairment
Nursing Interventions and Rationales:
- Implement fall prevention protocol
Rationale: Reduces risk of injury - Modify the environment for safety
Rationale: Creates safer space for movement - Teach fall prevention strategies
Rationale: Empowers patient to maintain safety
Desired Outcomes:
- The patient will demonstrate safe mobility practices
- Patient will identify and avoid fall risks
- The patient will remain free from falls
Nursing Care Plan 4: Activity Intolerance
Nursing Diagnosis Statement:
Activity Intolerance related to decreased endurance as evidenced by fatigue with minimal exertion.
Related Factors:
- Deconditioning
- Chronic illness
- Poor endurance
- Respiratory compromise
- Cardiovascular conditions
Nursing Interventions and Rationales:
- Establish an appropriate activity schedule
Rationale: Prevents overexertion while building stamina - Monitor vital signs during activity
Rationale: Ensures safe exercise tolerance - Teach pacing techniques
Rationale: Promotes optimal energy utilization
Desired Outcomes:
- The patient will demonstrate improved activity tolerance.
- The patient will maintain stable vital signs during activity
- The patient will report decreased fatigue
Nursing Care Plan 5: Disturbed Body Image
Nursing Diagnosis Statement:
Disturbed Body Image related to functional limitations as evidenced by feelings of helplessness and frustration.
Related Factors:
- Loss of independence
- Changed physical capabilities
- Altered role performance
- Social isolation
- Depression
Nursing Interventions and Rationales:
- Assess the psychological impact of functional limitations
Rationale: Identifies emotional needs and concerns - Promote positive coping strategies
Rationale: Enhances adaptation to changed abilities - Encourage participation in support groups
Rationale: Provides peer support and shared experiences
Desired Outcomes:
- The patient will express acceptance of the current functional status
- The patient will demonstrate positive coping strategies
- The patient will maintain social connections
