Disorders of the Muscle Flashcards
What is the purpose of the musculoskeletal system?
Protect organs, provide support and stability, and enable coordinated movement.
What are the components of a neurovascular assessment?
Pain and swelling, paresthesia, paralysis, pulses and capillary refill, pallor and temperature.
What is paresthesia?
Numbness and tingling.
What is a normal pulse rating?
2+.
What is the normal capillary refill time?
Less than 3 seconds.
What is a strain?
Stretching of a muscle or tendon.
What is a sprain?
Injury to a ligament surrounding a joint, usually occurs due to twisting.
What are the signs and symptoms of sprains and strains?
Pain, swelling, decreased function, and bruising.
What does RICE stand for?
Rest, Ice, Compression, Elevation.
What are safety concerns with compression?
Monitor for numbness and tingling, loosen bandage if needed, wrap distally.
What are the signs and symptoms of dislocation?
Deformity, pain and tenderness, local swelling, and loss of function.
What can increase the risk of dislocation?
Paralysis after a stroke (arm hangs and gravity pulls it out of socket). Prevent this by putting the paralyzed arm in a sling.
What is the difference between dislocation and subluxation?
Dislocation is a complete separation, while subluxation is a partial separation.
What is the treatment for dislocation?
Reduction: closed (manually) or open (surgically).
Why is a dislocation considered an orthopedic emergency?
Avascular necrosis or death of the surrounding tissue occurs if blood supply is cut off.
What is nursing care for dislocation?
Pain management, frequent neurovascular assessment, and joint support.
How long is a patient likely to wear a splint with a dislocation?
6-8 weeks; needs to be immobilized to heal.
What is carpal tunnel syndrome?
A repetitive use injury causing swelling of the carpal tunnel, leading to compression of the nerve.
What are the signs and symptoms of carpal tunnel syndrome?
Weakness, numbness and tingling, and pain.
What are the diagnostic tests for carpal tunnel syndrome?
Nerve conduction study, Phalen’s sign, Tinel’s sign.
What is Phalen’s sign?
Hands down pressed against each other, causing compression of the nerve, leading to numbness and tingling if the disorder is present.
What is Tinel’s sign?
Tapping over the nerve on the wrist, causing numbness and tingling if the disorder is present.
How can carpal tunnel disease be prevented?
Ergonomics: proper body mechanics and anatomical position.
What are the treatments for carpal tunnel disease?
Brace/splint, exercise, corticosteroid injections, and carpal tunnel release.
What are the types of rotator cuff injury?
Gradual (over time/repeated use) and sudden.
What are the signs and symptoms of a rotator cuff injury?
Weakness, pain, and inability to maintain abduction (arm out away from body).
What is the drop arm test?
The nurse holds the patient’s arm out and then lets go; the patient should try to hold the arm out after they let go. A person with this injury will not be able to.
What is a rotator cuff injury?
Injury to a group of muscles and tendons around the shoulder.
What is the diagnosis for a rotator cuff injury?
MRI, which shows soft tissues.
What is the treatment for a rotator cuff injury?
NSAIDs (for gradual tear), corticosteroid injections, ice/heat, support (sling), and surgery.
What is arthroscopic surgery?
Use of a scope that is placed into the joint; it is outpatient.
What are the post-operative care steps for arthroscopy?
Frequent neurovascular checks, compression bandage, limit activity, elevate, ice, and monitor for infection.
What is a greenstick fracture?
An incomplete fracture where the bone is bent but only partially broken; most common in children due to not having set bones.
What are the signs and symptoms of a fracture?
Deformity, pain, swelling, decreased function, erythema, bruising, and crepitation.
What is crepitation?
The grating sound heard when the ends of a broken bone move together.
What are the goals of care for a fracture?
Reduction of fracture, immobilization, and restoring fracture.
