ch. 47 mobility and immobility Flashcards
body mechanics
musculoskeletal and nervous system
alignment and balance
- center of gravity is stable
- correct body alignment
- contributes balance
- conservation of energy
skeletal system
- attachments for muscles and ligaments
- provides leverage for movement
- consists of bones, joints, ligaments, tendons, cartilage
skeletal muscles
-movement of bones and joints
concentric
increased musce contraction causes muscle shortening, which results in movement
eccentric
helps to control the speed and direction of movement
isometric
static contraction (posture, muscle tone)
isotonic
muscles that work together
nervous systen
regulates movement and posture
postural abnormalities
scoliosis
impaired muscle dev.
muscular dystrophy
damage to the CNS
spinal cord injury, meningitis
direct trauma to the musculoskeletal system
fractures, contusions
nursing knowledge base
- mobility: the ability to move about freely
- immobility: inability to move about freely
- bedrest: an intervention that restricts clients for therapeutic reasons
systemic effects of immobility
-metabolic changes
+endocrine
+Gi function
-respiratory changes
+decreased respiratory movement (decrease oxygen and co2 exchange)
+stasis of secretion and decreased respiratory muscles
(atelectasis & hypostatic pneumonia)
cardiovascular changes
-VS changes
musculoskeletal changes
- loss of endurance and muscle mass and decreased stability
- muscle effects
- skeletal effects
urinary elimination
- decrease output
- difficulty
integumentary
- skin turgor
- skin breakdown
psychosocial effects
sensory deprivation
dev. changes
Infants, toddlers, and preschoolers
-prolonged immobility delays gross motor skills, intellectual dev., or musculoskeletal dev.
dev. changes
adolescents
Delayed in gaining independence and in accomplishing skills
dev. changes
adults
all physiological systems are at risk; changes in family and social structure
dev. changes
older adults
- decreased physical activity, alterations in balance, hormonal changes
- women: menopause
