2. Explain the structure and function of the musculoskeletal system
Define the following terms: muscles groups of tissues that contract and relax, allowing motion, supporting the body, protecting organs, and creating heat. bones rigid connective tissues that make up the skeleton, lend support to body structures, allow the body to move, and protect the organs. joints the points where two bones meet; provide movement and flexibility.

Define the following terms: cartilage the protective substance that covers the ends of bones and makes up the discs that are found between vertebrae. bursae tiny sacs of fluid that are located near joints and help reduce friction. tendons tough fibrous bands that connect muscle to bone. ligaments strong bands of fibrous connective tissue that connect bones or cartilage and support the joints and joint movement.

Transparency 21-1: The Musculoskeletal System

Know the three types of muscles: Skeletal muscles Also called voluntary muscles, these muscles control body movements by contracting and relaxing. A voluntary muscle is a muscle that can be controlled voluntarily, or at will. Smooth muscles Also called involuntary muscles, these muscles make up the walls of organs, such as the bladder and uterus. Involuntary muscles are controlled automatically and are not under a person’s conscious control.

Three types of muscles (cont’d.): Cardiac muscles Another type of involuntary muscles, these muscles are found only in the heart. The cardiac muscles contract and relax anywhere from 60 to 100 times each minute.

Know the four types of bones: Long bones: e.g. the humerus (upper arm bone), the femur (upper leg or thigh bone) Short bones: e.g. carpals (wrist bones), tarsals (ankle bones) Flat bones: the sternum (breastbone) and scapula (shoulder blade) Irregular bones: bones of the vertebrae (spine)

Know the three types of joints: Immovable joints: Examples of immovable joints are the bones of the cranium (skull). Slightly movable joints: An example of a slightly movable joint is the joint between the pubic bones. Movable joints: The joint between the scapula and the humerus is an example of a freely movable joint. Other types of movable joints are the hip and shoulder joints, which are ball-and-socket joints, and the elbow and knee joints, which are types of hinge joints.

Functions of the musculoskeletal system: Gives shape and form to the body Maintains posture Permits movement Protects internal organs Stores calcium and phosphorus Produces heat Produces some blood cells

3. Discuss changes in the musculoskeletal system due to aging
Normal changes of aging in the musculoskeletal system: Muscles weaken and lose tone. Bones lose calcium, causing them to become porous and brittle. Height is gradually lost due to shrinkage of space between the vertebrae in the spine. Loss of muscle mass in the body causes weight loss. Joints are less flexible and stiffer, which slows normal body movements and decreases range of motion.

4. Discuss common disorders of the musculoskeletal system
Define the following term: muscular dystrophy an inherited, progressive disease that causes a gradual wasting of muscle, weakness, and deformity.

Know these points about muscular dystrophy: Hereditary, progressive disease in which muscle tissue is destroyed and muscles atrophy Symptoms: muscle weakness, stiffness, twitching of the hands and arms Cause: specific gene in the body Generally appears at birth or during childhood There is currently no cure.

Remember these care guidelines for muscular dystrophy: Allow time for movement. Give frequent skin care to prevent pressure ulcers. Reposition residents often to prevent contractures. Perform ROM exercises as directed. Assist with ADLs. Encourage independence. Report red skin; pale skin; signs of the beginning of a pressure ulcer; stiffening of muscles; pain, swelling, or burning in a leg; symptoms of UTI; or signs of pneumonia.

Define the following term: osteoporosis a condition in which the bones become brittle and weak; may be due to age, lack of hormones, not enough calcium in bones, or lack of exercise.

Know these points about osteoporosis: Bones lose mass, causing them to become brittle. Causes: lack of calcium in diet, loss of estrogen, lack of regular exercise, reduced mobility, age More common in women, especially after menopause Symptoms: low back pain, loss of height, fractures, stooped posture Treatment: medication, exercise, calcium supplements Be patient and reposition residents carefully. Report any decline in activity or movement.

Define the following terms: arthritis a general term that refers to inflammation of the joints. osteoarthritis a type of arthritis that usually affects weight-bearing joints, especially the hips and knees; also called degenerative joint disease. rheumatoid arthritis a type of arthritis in which joints become red, swollen, and very painful; movement is restricted and deformities of the hands are common.

Know these points about arthritis: General term for inflammation of joints that cause pain, stiffness and swelling May cause decreased mobility

Know these points about osteoarthritis: Condition in which cartilage between bones and the pads at the ends of bones begins to erode. Symptoms: pain, redness, swelling, stiffness, limited motion Generally occurs due to aging and may be due to joint injury Cold, damp weather can increase pain and stiffness.

Know these points about rheumatoid arthritis: Form of arthritis that may become crippling Symptoms: stiffness, swelling, severe pain, deformities which may be severe and disabling, fever, fatigue, weight loss Cause: autoimmune illness Treatment: rest, controlled exercise, ROM exercises, medication, weight loss, heat applications, joint replacement

Remember these care guidelines for arthritis: Assist with exercise program. Perform ROM exercises as directed. Let nurse know, before exercise, if pain medication is needed. Assist with ADLs as needed. Encourage use of handrails and safety bars in bathroom. Be positive and supportive; listen if resident wants to talk. Report stiffness, swelling, pain, reduced ability to perform ROM exercises, or decline in activity.

Define the following term: bursitis a condition in which the bursae become inflamed and painful.

Know these points about bursitis: Condition in which bursae become inflamed Symptoms: tissue around joint may become painful, swollen, and tender Treatment: application of ice, immobilization to rest joint, medication, removal of fluid from joint, and cortisone injections

Define the following terms: amputation the surgical removal of an extremity. prosthesis an artificial device that replaces a body part, such as an eye, hip, arm, leg, tooth, or heart valve; helps improve function and/or appearance. phantom sensation warmth, itching, or tingling from a body part that has been amputated. phantom limb pain pain in a limb (or extremity) that has been amputated.

Keep resident in proper body alignment. Report numbness or tingling, cyanosis or pale skin, wetness on sling, odor around sling or boot, sling or boot becomes loose or comes off, pain, burning, pressure, swelling, changes in skin temperature, redness, drainage, bleeding, sores, or resident moving to the side or sliding down.

5. Describe elastic bandages
Know these points about elastic bandages: Bandages that are wrapped around a body part Used to keep dressings in place, hold splints in place, and provide protection, compression and support for body parts, decrease swelling from injuries and hold ice in place Must be snug enough to provide proper compression and support but not interfere with circulation Report pale, gray, cyanotic, or white skin; skin that is cold to the touch; swelling; complaints of bandage feeling too tight; pain or discomfort; numbness or tingling

Know the “RICE” acronym: Rest: Rest is important to help an injury heal properly. Putting any weight on the injury could cause more harm. Ice: Ice helps to prevent or reduce swelling. The skin should always be protected when using ice. Compression: As you have learned, elastic bandages are used to compress the injured area, hold the extremity in place, and reduce discomfort. In addition, elastic bandages help decrease tissue swelling that occurs with an injury. Elevation: Elevating the extremity also helps prevent or reduce swelling. When an extremity is elevated above the level of the heart, swelling may decrease.

REMEMBER: Memorize the “RICE” (Rest, Ice, Compression, Elevation) acronym for care when a person is injured.

Applying elastic bandages
Equipment: elastic bandage in the correct size, clip, safety pin, or tape (if using self- adhering bandage, these are not needed) 1. Identify yourself by name. Identify the resident. Greet the resident by name. 2. Wash your hands. 3. Explain procedure to resident. Speak clearly, slowly, and directly. Maintain face-to-face contact whenever possible.

4. Provide for the resident’s privacy with a curtain, screen, or door. 5. Adjust bed to safe working level, usually waist high. Lock bed wheels. 6. Avoid trauma or pain to the resident throughout the procedure. 7. Assist resident to get into the supine (flat on the back) position. 8. Expose only the part to be bandaged.

9. Hold the rolled bandage with one hand and, with the other hand, put the loose end on top of the extremity. 10. Wrap extremity, beginning at the spot furthest from the heart. Circulation returns toward the heart, and this allows extra fluid to flow to the heart and leave the area. (For the wrist, begin wrapping at the hand. For the ankle, begin at the foot.)

(For the wrist, begin wrapping at the hand. For the ankle, begin at the foot.) 11. Wrap bandage once around the beginning spot, and turn over the tip so that an anchor is made. 12. Wrap one more time around the spot where the anchor lies, and then begin slowly wrapping in overlapping spirals up the extremity. 13. Smooth out entire bandage, removing any wrinkles.

14. Secure bandage with self-closure, clip, safety pin, or tape. If using a pin, be careful not to pierce the resident’s skin. 15. Straighten all of the linens. 16. Remove and re-apply bandage as directed. Wash and dry bandages as necessary. 17. Make resident comfortable.

18. Return bed to lowest position. Remove privacy measures. 19. Leave call light within resident’s reach. 20. Wash your hands. 21. Be courteous and respectful at all times. 22. Report any changes in the resident to the nurse. Document procedure using facility guidelines.
