Effects of Immobility and Risk Assessment

Effects of Immobility

Any disorder which impairs:
Nervous System
Musculoskeletal System
Cardiovascular System
Vestibular System

Effects on Musculoskeletal System

~Disuse osteoporosis: bones demineralize (osteoporosis) Loss of Calcium
~Disuse atrophy: unused muscles atrophy
~Contractures: a shortening of the muscle
~Stiffness and pain of the joint: collagen tissue "ankyloses" -> as bone demineralizes, excess Ca bec

Effects on Cardiovascular System (1 of 6)

~Tachycardia (less blood flow to the coronary arteries)
~Increased used of Valsalva maneuver (increases pressure in veins of the thorax)
~Orthostatic hypertension (blood pooling of the blood in lower extremities)
~Venous dilation (blood pooling results in

Parameters of Orthostatic Hypotension

HR increased by 15%
Drop in systolic BP by 15 mmHg
Drop in diastolic BP by 10 mmHg

Effects on Respiratory System

~Decreased respiratory movement (shallow breathing and client rarely sighs)
~Pooling of secretions (rarely sighs, lack of coughing)
~Atelectasis or secretions pool in one area of lung (collapse of lobe or lung)
~Hypostatic Pneumonia (pooled secretions = e

Effects of the Metabolic System

~Decreased BMR (slows down perastalsis)
~Negative nitrogen balance (increased catabolism) -> malnutrition
~Anorexia (decreased BMR)
~Negative calcium balance (greater calcium is extracted from bones than can be replaced)
~Delayed wound healing (protein in

Effects on the Urinary System

~Urinary Stasis (incomplete emptying of kidneys and bladder)
~Renal Calculi (excess amount of calcium -> calcium salts precipitate to form renal stones)
~Urinary Retention (bladder doesnt empty completely, decreased muscle tone)
~Urinary Infection (increa

Effects on Gl System

~Constipation (decreased peristalsis, inadequate hydration, diet)
~Increased Use of Valsalva Manuever

Effects on the Integumentary System

~Reduced skin turgor (atrophy of skin)
~Skin breakdown (decreased circulation to the skin and pressure of immobility)

Effects on the Psychoneurological System

~Decreased endorphins (lack of exercise)
~Decreased self esteem (increased dependence on others)
~Decreased stimuli

Assessments/Interventions: Musculoskeletal System

~Check muscle tone
~Assessement of ROM
~Falls Risk
~ROM (passive and active)

Assessments/Interventions: Cardiovascular System

~BP monitoring (check for orthostatic changes)
~Evaluate peripheral pulses
~Check for venous stasis and edema
~Education regarding Valsalva maneuver (encourage to breathe thru mouth)
~Prevent DVT: Use of SCD or Ted Hose

Assessments/Interventions: Respiratory System

~Encourage cough and deep breathing
~Use incentive spirometer
~Auscultate the lungs

Assessments/Interventions: Metabolic System

~Check height, weight and skinfold thickness (evaluate muscle atrophy)
~Provide HIGH protein, HIGH calorie diet
~Monitor Lab values (serum protein, albumin and BUN)

Assessments/Interventions: Urinary System

~Monitor I & O
~Hydration

Assessments/Interventions: GI System

~Monitor food intake and elimination patterns
~Assess bowel sounds
~Diet HIGH in fiber, fruits and vegetables

Assessments/Interventions: Integumentary System

~Assess for skin breakdown
~Turn Q 2 hours
~Evaluate risk of breakdown using (Braden Scale)
~Skin Care Q shift

Assessments/Interventions: Psychoneurological System

~Evaluate for confusion, feelings of boredom and isolation, depression
~Maintain sleep cycle
~Prevent social isolation
~Encourage client to perform ADLs

Risk Factor

Any situation, habit, social or environment condition, physiological or psychological condition, developmental or intellectual condition, or spiritual or other VARIABLE that INCREASES the VULNERABILITY of an individual group to an illness or accident

Internal Variables: Biological dimension

~Genetic make-up
~Gender
~Age
~Developmental level
~Psychological Dimensions (mind body interaction & self concept)
~Cognitive Dimensions (lifestyle choices & spiritual and religious beliefs)

External Variables

~Environment
~Standards of Living

Database for Risk Assessment: Health History

1. Demographics: age, gender and ethnicity
2. Past health hx: accidents or injuries, chronic disease
3. Family hx: heart disease, diabetes, breast cancer, arthritis, alcoholism

Database for Risk Assessment: Review of System (ROS)

~Non-modifiable risks (Heredity, Age, Gender, Post-Menopausal women)
~Modifiable risks (Elevated serum lipids, hypertension, cigarette smoking, obesity, sedentary lifestyle)

Sensitive information: Health History or ROS

Stress: a condition in which a person experiences changes in the normal balanced state
Holmes and Rahe Social Readjustment Rating Scale (rates positive and negative life events)

Braden Scale

Assess the development of pressure ulcers (decubitus ulcers or bedsores)

Etiology of Pressure Ulcer

~Caused by localized ischemia
~Tissue compressed between bed and bony area
~After compression -> area of pale skin
~After pressure is relieved -> bright red, called "reactive hyperemia"
~If redness disappears -> no permanent damage
~If redness persists ->

Risk Factors: Pressure Ulcers

~Friction and shearing
~Immobility
~Inadequate nutrition
~Incontinence
~Decreased mental status
~Diminished sensation
~Excessive body heat
~Advancing age
~Chronic medical conditions

Maceration

Tissue is softened

Excoriation aka denuded

Loss of superficial layer

Stage 1: Pressure Ulcers

Non-blanchable erythema, signals a potential ulceration

Stage 2: Pressure Ulcers

Partial thickness loss, abrasion, blister, shallow crater which involves the epidermis and possibly the dermis

Stage 3: Pressure Ulcers

Full thickness skin loss, involves damage or necrosis to the subcutaneous tissue that my extend down to the fascia but not thru the fascia

Stage 4: Pressure Ulcers

Full thickness skin loss with TISSUE NECROSIS or DAMAGE to the muscle, bone or supporting structures

Falls Risk Assessment

Designed to prevent clients from falling and to minimize injury from falls

Risk vs high risk clients

High risk with one or more risk factors, if admission is related to a fall, or if determined by the RN

High Risk Clients

~ID bands with yellow arm band
~Yellow safety tag on the door
~Order for FFP
~Implement high risk falls prevention measures

Falls Risk Test

Sit for short time, stand, walk more than 10 ft and then sit again

Interventions

~Take to bathroom every 2 hours during the day, every 4 hours at night
~Check for orthostatic changes, dizziness or lightheadedness when up
~Move closer to nursing station
~Bed/Chair exit alarm
~Reorient
~Encourage family involvement
~Sitter
~Bed in LOW p

Bed Entrapment

An event in which a patient is caught trapped or entangled in the space in or above the bed rail, mattress or hospital bed frame which may result in serious injury or death

Zones of Bed Entrapment

Within the rail
Between rail and mattress
Between split rails
Between end rail and side edge of head or foot board
Between head of foot board and mattress end

Physical Restraint

Bed rails are considered a physical restraint if it prohibits freedom of movement within the environment

Interventions: Bed Entrapment

~Monitor Q 1 hr
~Anticipate needs
~Use of wedges and padding between mattress and side rails
~Ensure call light within reach
~Move client closer to nursing station
~Consider sitter
~Use minimum bedrails for safety and comfort

Aspiration

The entry of gastric secretions, oropharyngeal secretions or food and fluids into the tracheobronchial tree due to dysfunction of normal protective mechanisms

Risk factors: Aspiration

Neurological or nueromuscular disease, trauma or SURGICAL PROCEDURES of the ORAL cavity and THROAT

Dysphagia

Refers to difficulty when swallowing
Can lead to aspiration, pneumonia, decreased nutritional status

Risk Factors: Dysphagia

Neurological and neuromuscular diseases; obstructive diseases of the GI tract
