Question 20

internal rotation

Answer 20

a body part turning on it’s axis toward the midline of the body

Question 21

inversion

Answer 21

Movement of the sole of the food inward (occurs at the ankle)

Question 22

Kyphosis

Answer 22

An increased thoracic spinal curve, More often seen in older adults

Question 23

ligaments

Answer 23

tough fibrosis bands that bind joints together and connect bones and cartilage

Question 24

long bones

Answer 24

found in the upper and lower extremities contribute to height and length

Question 25

lordosis

Answer 25

an exaggerated lumbar curve is often seen during pregnancy or in obesity

Question 26

muscle mass

Answer 26

refers to muscle size

Question 27

atrophy

Answer 27

is decreased muscle mass due to disuse or neurologic impairment

Question 28

hypertrophy

Answer 28

increased muscle mass resulting from exercise

Question 29

muscle tone

Answer 29

the slight residual tension that remains in a resting normal muscle with an intact nerve supply.

Question 30

Flaccidity

Answer 30

decreased tone resulting from disuse or neurologic imparments.

Question 31

spasticity

Answer 31

increased tone that interferes with movement, also caused by neurologic impairments

Question 32

paraplegia

Answer 32

paralysis of the leg

Question 33

paresis

Answer 33

imparied muscle strength or weakness

Question 34

pivot joint

Answer 34

a ringlike structure that turns on a pivot (Joints between the proximal ends of the radius and the ulna) Movement is limited to rotation

Question 35

Plantar flexion

Answer 35

Flexion of the foot (foot drop)

Question 36

pronation

Answer 36

the assumption of the prone position

Question 37

quadriplegia

Answer 37

paralysis of the arms and legs

Question 38

range of motion

Answer 38

the complete extent of movement of which a joint is normally capable.

Question 39

Active range of motion:

Answer 39

the patient independently moves joints through their full range of motion.

Question 40

active-assistive range of motion

Answer 40

the nurse may provide minimal support

Question 41

passive rant of motion

Answer 41

the patient is unable to move independently and the nurse moves each joint through it’s range of motion

Question 42

rotation

Answer 42

turning on an axis

Question 43

saddle joint

Answer 43

bone surfaces are convex on one side and concave on the other (Joint between the trapezium and metacarpal of the thumb) Movements are side to side and back and forth

Question 44

Scoliosis

Answer 44

A lateral curvature of the spine with increased convexity of the side that is curved

Question 45
