Chapter 18 Flashcards
What are the four types of bones?
Short, long, flat and irregular
A small fluid- filled sac that provides a cushion at friction points in the joints
Bursa
A union of two or more bones; moves freely
joint
Striated muscles surrounded by a connective tissue sheath
Skeletal muscle
Fibrous tissue that connects muscle to bone
Tendon
Connect bone to cartilage
Ligament
Fibrous connective tissue; acts as a cushion
Cartilage
What are the functions of muscles?
Can stretch; can be stimulated to contract electrically or to extend elastically
What happens with your body as you age?
*Bone mass loss may lead to osteoporosis (more severe in woman)
*Loss of bone density predisposes the elderly to fractures
*Muscle cells are lost and replaced by fat cells
*Elasticity of muscle fibers is decreased, limiting flexibility
*Joint motion may decrease, limiting motion and mobility
What is the most common injury that health care workers get?
Lower back strain
How can injuries be prevented?
Proper body movement is essential to prevent injuries.
What are the benefits of core exercises as related to your back?
Core exercises can help keep your back healthy and strong. Core exercises train the muscles in your abdomen, pelvis, lower back, and hips to work together, leading to improved balance and stability.
What should you do if you have difficulty finding a staff person to help you?
It is always better to wait for help than to risk injury.
What are the two basic principles?
-Maintain correct anatomic position
-Change position frequently
What are the hazards of improper alignment and positioning
-Interference with circulation, which may lead to pressure ulcers
-Muscle cramps and possible contractures
-Fluid collection in the lungs
What are contractures?
Resistance to stretch in damaged muscle that pulls a joint into a fixed or “frozen” position
How can contractures be prevented?
Body positioning
What is shearing force?
Shearing is an applied force that causes a downward and forward pressure on the tissues beneath the skin. Shearing forces occur when a patient slides down in a chair, bedclothes are pulled from beneath the patient, or the patient is slid up to the head of the bed without lifting the body.
_____ Also known as decubitus ulcers, or bedsores
Pressure ulcers
What questions would be asked during the assessment of the standing patient’s body alignment?
Is the head centered and erect? Are the shoulders and hips parallel? Are the knees and ankles slightly flexed and parallel to the hips and shoulders? Do the arms hang comfortably at the patient’s side? Are the feet slightly apart to provide a base of support?
What is symmetry?
Equality in size, form, and arrangement of parts on the opposite sides of a plane; a mirror image
What are commonly used problem statements?
-Potential for injury
-Altered mobility
-Potential for altered skin integrity
What are some therapeutic exercise?
-Prevent injury and immobility
-Restore function of muscles, nerves, bones, and joints
-Prevent deformity and stimulate circulation
-Build tolerance and endurance
When moving a patient, it is important to use proper body mechanics. Which of the following is not a proper body mechanic?
A)Using your leg muscles
B)Keeping your feet together to provide stability for movement
C)Using smooth, coordinated movements instead of jerking or sudden movements
D)Keeping loads as well as your elbows close to the body
B)Keeping your feet together to provide stability for movement
