ati mobility

Question 1

mobility

Answer 1

another way to say motion or movement

- body designed for motion requires muscles, skelton, and nerve to function in unison

Question 2

nursing goal for mobility

Answer 2

assist in preserving, maintaining, and restoring as much mobility and function as possible

Question 3

muscular system

Answer 3

• provides motor power
• 600 muscles
• half person weight
• when contracted across a joint, creates a force to pull against the skelton
• high demand for oxygen and glucose

Question 4

four properties of a muscle

Answer 4

(CEEE)

• contractibility: ability to shorten and than relax
• Excitability: muscle fibers can receive and respond to nerve or hormone stem. resting muscle is negatively charged. When stimulated (excited), it becomes positively charged and active
• Extensibility: ability to stretch which occurs stimulations as other muscles contract
• elasticity: ability to bounce back or recoil to its original state after being contracted or extended

Question 5

3 main muscle types

Answer 5

• cardiac: only located in heart and functions involuntarily
• smooth: located in blood vessels and the visceral organs and functions involuntarily
• skeletal: attached to skeleton by tendons and functions voluntarily

Question 6

skeletal system

Answer 6

• 206 bones
• bones are hard connective tissue
• protect and support internal organs and muscles
• store important minerals
• composed of layers

Question 7

once bones matured they undergo

Answer 7

process of remodeling where old bone is constantly being replaced with new bone

Question 8

cartilage

Answer 8

firm yet flexible connective tissue

- ears, nose, larynx, ribs, intervertebral discs, knees, ankles

Question 9

flexion

Answer 9

bend, reduces angle between bones

Question 10

extension

Answer 10

straighten the limb

Question 11

abduction

Answer 11

move away from baseline

Question 12

adduction

Answer 12

bring closer to baseline

Question 13

pronation

Answer 13

turning face backwards

Question 14

supination

Answer 14

turing to face forward

Question 15

circumduction

Answer 15

circular motion

Question 16

rotation

Answer 16

side to side

Question 17

inversion

Answer 17

turn inward

Question 18

eversion

Answer 18

turn outward

Question 19

dorsiflexion

Answer 19

draw toes upward towards body

Question 20

plantar flexion

Answer 20

point toes downward away from body

Question 21

body mechanics

Answer 21

combined effort from musculoskeletal system an nervous system to maintain posture, alignment, and balance in daily life

• knowledge in coordination and integrated function of both system to maximize strength and minimize strain
• good posture in motion

Question 22

lordosis

Answer 22

lower back curves inward with pelvis tilting anteriorly

Question 23

kyphosis

Answer 23

upper back is abnormal rounded with a forward tilt in pelvis

Question 24

flat back

Answer 24

loss in curvature to the spine referred to as straight back

Question 25

sway back

Answer 25

extends backward while lower back abnormally curves inward and the pelvis tilts forward - positioning the head in front of the pelvis; resulting from loss of muscle tone in ab and lower back, which allows spine to sag

Question 26

scoliosis

Answer 26

c or s shaping os spine

Question 27

activity intolerance

Answer 27

inadequate amount of physical or phyiolgical energy to undergo or complete necessary activity

Question 28

activity tolerance

Answer 28

capacity to successfully complete a necessary activity without distress

Question 29

activity of daily living

Answer 29

basic essential skills that a person does independent every day and are usually related to personal care

Question 30

proper positioning

Answer 30

intentionally placing body or body part in specific way - involved alignment body in neutral position, supporting body natural curves, and eliminating pressure points, hyperextension or lateral rotation - goals for client positioning and alignment consist of the two ps promotion and prevention

Question 31

immobility

Answer 31

inability to move one or more body parts - detrimental to body negatively affecting all major system in a critical cascade to dependency - on joints are stiffness, pain and limited range of motion, especially shoulders, elbows, hips, knees, and ankles

Question 32

prolonged immobility

Answer 32

prolonged causes formation of fibrofatty connective tissue and abnormal adhesions within and between joint space, which restricts nourishment to joints

Question 33

prolonged bed rest

Answer 33

prolonged best rest causes blood flow to slow (venous stasis) increasing risk for clots
