Immobility and Activity Study Guide
Mobility
A decline in a patient’s mobility status can result from illnesses, injuries, ______
Immobility occurs when a patient is unable to move independently or is restricted for therapeutic reasons (e.g., casts, bedrest)
The longer the immobility, the more pronounced the consequences on body systems
Effects of Immobility
Respiratory: decreased lung expansion, generalized respiratory muscle weakness, and stasis of secretions
- Can lead to atelectasis and hypostatic pneumonia
Changes in ______: BMR decreases; decreases ability to produce insulin and metabolize glucose so begins to break down protein stores (muscle). This leads to negative nitrogen balance which predisposes to problems with wound healing
Effects of Immobility
Fluid and Electrolyte Changes: Diuresis occurs as result of increased blood flow to kidneys, which causes loss of electrolytes (potassium and sodium). Also causes calcium resorption (loss) from bones which causes elevated serum calcium levels (hypercalcemia).
GI Changes: Risk of constipation from decreased peristalsis and hypercalcemia. Can become a partial or complete bowel obstruction.
Cardiovascular
- Orthostatic hypotension occurs after prolonged sitting or patients on bedrest due to blood pooling in the extremities; is a SBP drop of 20mm Hg or more or a DBP drop of 10mm Hg or more when patient stands
- Bedrest also increases HR 4-15 beats/min and increased rate is more pronounced on activity
- Risk for DVT/thrombus which puts them at risk for PE which can be life-threatening.
Musculoskeletal changes
- Loss of strength and endurance, decreased muscle mass and decreased balance. Affects the leg muscles the most.
- 2 possible skeletal complications:
- Joint contractures: foot drop is common
- Disuse osteoporosis with risk of pathological fractures
Integument Changes: risk for pressure ulcers due to pressure and changes in metabolism
Urinary Elimination Changes:
- Urinary stasis from gravity not pulling urine into ureters and bladder.
- Increases risk for ______and renal calculi (kidney stones). (Hypercalcemia further increases risk.)
Psychosocial Effects: reduces a patient’s independence and creates a sense of loss. Common emotional changes are depression, sleep-wake disturbances, and impaired coping.
Developmental Effects in children and older adult
Assessing for Potential Effects of Immobility
Respiratory: Assess at least every 2 hours for acutely ill patients
Metabolic
- Monitor weight, BMI
- Monitor I &O and lab data: fluid electrolyte status
- Assess food intake/appetite
- Monitor wounds for healing if present
Cardiovascular:
- monitor BP and check for orthostatic hypotension
- Monitor apical and peripheral pulses
- Assess for Edema
- Assess for DVT every ______(swelling, redness, warmth, tenderness, calf pain. Homans is no longer considered accurate predictor of DVT). 50% are Asymptomatic!
Musculoskeletal: assess for decreased muscle strength, contractures
Skin Integrity: Assess for pressure ulcers
Elimination: Assess status every shift as well as total I/O over past 24 hrs. Also auscultate for bowel sounds and assess the frequency and consistency of bowel movements
Psychosocial: observe for changes in mood, behavior and sleep
Planning
Encouraging/providing ROM and repositioning is first step in preventing complications
Pain may need to be managed first
Implementation
Structured Exercise Programs
Respiratory:
- Promote Expansion of Chest and Lungs by repositioning and encouraging incentive spirometry/deep breathing. Post-op patients may need pain meds for incisional discomfort first
- Prevent stasis of secretions by repositioning and encouraging ______fluid intake daily if not contraindicated
- If patient is too weak, you may need to suction
Metabolic: work with dietician to promote good diet plan
Cardiovascular
- Reduce orthostatic hypotension:
- Get patient moving ASAP, even if this means dangling on bed or sitting in chair
- Isometric exercises improve activity tolerance
- When transferring, do it gradually
- Prevent thrombi by:
- Being cautious with pressure on posterior knee
- ROM exercises like ankle pumps, foot circles, and knee flexion
- Encourage Elastic stockings and sequential compression devices (requires order)
- Prophylactic low-dose heparin therapy (requires order)
- Teach patient to avoid ______response (it could be deadly)
- If you suspect a DVT, do not massage; Report immediately to the health care provider
Musculoskeletal
- A total of 2 hours in 24 hour period scheduled throughout the day will prevent disuse syndromes. Best method: ambulation
- Passive ROM for immobilized joints 3 or 4 times a day
- Devices like hand rolls, trapeze bars
- Individualize a Progressive Exercise Program with a physical therapist, if possible
Skin Integrity
- Reposition patient every 1-2 hours or teach to shift weight every 15 minutes
- Use pressure-reducing devices; keep heels elevated off the bed
Elimination
- Monitor urine output and bowel movements
- Initiate bowel training program if unable to maintain normal pattern
Psychosocial
- Provide routine and informal socialization
- Place in room with other patients
- Provide stimuli to entertain
- Encourage patients to wear glasses and dentures, shave and apply makeup to enhance body image
- Minimize sleep disruptions
- Observe for failure to cope
In Continuing Care
Goal is to maximize independence, increase endurance and prevent injury
Focus on IADLs as well as ADLs
Ch. 25 Exercise and Activity
Implementation: Positioning Techniques
- Fowler’s position
- Supine position
- Prone position
- Lateral position
- Sim’s position
Review:
- Transfer techniques
- Assisting a patient in walking
- What to do if they feel dizzy or start to fall
Don’t Forget: Prevent Back Injury While Repositioning Clients
Always use proper body mechanics while transferring patients
Do not be afraid to ask for assistance
Do not try to reposition someone alone who requires the assistance of two
Repeated injury to your back can cause a lifetime of back pain!
