Ch. 8: Body Mechanics and Patient Mobility Flashcards
Body mechanics
area of physiology that studies muscle action and how muscles function in maintaining the posture of the body and prevention of injury during activity
Principles of body mechanics
maintain appropriate body alignment
maintain wide base of support
bend knees and hips
do not bend from waist
The second occupational injury
back injuries
Proper body mechanics
avoid twisting, carry objects close to the body and midline, avoid reaching too far, avoid lifting when other means of movement are available
Foot boot
maintains the foot in dorsiflexion position, prevents foot drop
Trochanter roll
prevents external rotation of legs when patient is in supine position
Trapeze bar
allows patient to roll from side to side or to sit up in bed
Bed board
provides additional firmness to mattress
Abductor splint
used to maintain legs in abduction after THR
Complications of immobility
muscle atrophy and asthenia, contractures, osteoporosis, pressure ulcer, constipation, pneumonia, pulmonary embolism
How often to reposition an immobile patient?
Every 2 hours
Anti-embolism measure
TED stockings, decompression boots
Dorsal
lying flat on back
Dorsal recumbent
supine lying on back, head, and shoulder with extremities moderately flexed
Fowler’s
head of bed is raised 45 to 60 degrees
Semi-fowler’s
head of bed is raised 30 degrees
Orthopenic
sitting up in bed at 90 degree angle or sometimes resting in forward tilt
Sims’
lying on side with knee and thigh drawn toward chest
Prone
lying face down in horizontal position
Knee-chest (genupectoral)
kneels so weight of body is supported by knees and chest, abdomen raised, head turned to one side and arms flexed
Lithotomy
lying supine with hips and knees flexed, thighs abducted and rotated externally
Trendelenburg’s
head is low, body and legs are on inclined plane
CSM
neurovascular function or circulation, movement, sensation
LPN/LVN check: skin color, temperature, movement, sensation, pulses, capillary refill, and pain
Compartment syndrome
compression created by external pressure or the accumulation of excessive tissue fluid from burns, fractures, crushing injuries or severely bruised muscles increases compartmental pressure, can also be caused by cast or tight bandage
Permanent nerve damage with irreversible muscle function can occur within
12 to 24 hours
Acute compartment syndrome
is an emergency
Fasciotomy
surgeon makes an incision into the skin and fascia to release the pressure, incision is left open until swelling subsides
Active ROM
performed by patient
Passive ROM
performed by caregivers
Range of motion exercises
movement of the body that involves the muscles and joints in natural directional movements
Physical disuse syndrome
physical state caused by bed rest or immobility and/or lack of physical activity
Moving the patient
assist with moving, assist with ambulation, using a lift
Continuous passive motion machines
machine that flexes and extends joints to passively mobilize them, prevents complications
Assessment
foci of ROM, muscle strength, activity tolerance, gait, posture; observe for fatigue, muscle strength, ROM; assistance needed for transfers
