| Nursing Management for radiography | no preparation needed |
| nursing management for CT-NPO | Nothing by mouth for 6-8 hours |
| nursing management for CT with contrast | find out if pt has allergy to iodine or shellfish |

| internal inspection of a joint using an instrument called an arthroscope | arthroscope |
| most common location for arthroscopy | knee joint |
| aspiration of synovial fluid; may be done to alleviate discomfort caused by excessive accumulation in the joint space or to inject a drug such as a corticosteroid | arthrocentesis |
| radiographic exam of a joint (usually shoulder or knee) with use of a contrast medium (pt may hear clicking or crackling for up to 2 days after procedure) | arthrogram |
| estimates bone density; radiography of the wrist, hip or spine - helps determine bone mineral density; nurse should watch for drainage after these tests | bone densitometry |
| uses IV injection of a radio-nuclide to detect the uptake fo the radioactive substance by the bone; detects metastatic bone lesions, fractures, and certain types of inflammatory disorders; radio-nuclide is taken up in areas of increased metabolism | bone scan |
| tests the electrical potential of the muscle and nerves leading to the muscle | electromyography |
| Why is electromyography done? | to differentiate muscle and nerve problems |
| detects levels of uric acid and calcium excretion | 24-hour urine test |
| Why would synovial fluid be aspirated and examined? | to diagnose disorders such as traumatic arthritis, septic arthritis (caused by a micro-organism), gout, rheumatic fever, and systemic lupus erythematosis |
| What color is normal synovial fluid? | clar and nearly colorless |
| What may be present in joint space after an injury? | blood cells, crystals, and formed debris |
| most common form of arthritis | osteoarthritis |
| Osteoarthritis is sometimes called: | degenerative joint disease |
| Osteoarthritis affects: | weight-bearing joints (mostly in people over 50) |
| Osteoarthritis is characterized by: | degeneration of articular cartilage with hypertrophy of the underlying and adjacent bone; bone surfaces rub together (hips, ankles); bone grows as bone spurs; shock absorbing protection is gradually lost; pt will have leukocytosis |
| Risk factors of osteoarthritis | older clients; previous joint injury; obesity; decrease in bone density |
| Early symptoms for osteoarthritis: | brief joint stiffness and pain after a period of inactivity; pain usually increases with heavy use and is relieved by rest; later - even rest may not relieve pain |
| Later symptoms of osteoarthritis: | may include joint enlargement with increased limitation of movement; crepetus (creaking) may be heard and felt when the joint is moved |
| When osteoarthritis affects the hands, fingers frequently develop _________. | bony nodules called Heberden's nodes and Bouchard's nodes |
| S/S of osteoarthritis: | pain along affected joint, stiffness and limitation of movement, mild tenderness, swelling and deformity or enlargement of a joint |
| Osteoarthritis usually affects how many joints? | usually a single joint or only a few |
| How is osteoarthritis diagnosed? | by health history and radiography studies; plain x-rays may not show cartilage abnormalities, and arthroscopy or MRI may be necessary |
| Medical treatment for osteoarthritis | heat therapy; splints; canes; weight loss; drug therapy; begins with Tylenol and NSAIDs; Cox-2 inhibitors or low-dose aspirin; Vioxx; Celebrex; narcotics (if other methods are not controlling pain); intra-articular injections of steroids 3 or 4 times/year |

| Surgical management for osteoarthritis is usally reserved for _________ | people with severe disease who respond poorly to conventional treatment |
| total joint replacement | arthroplasty |
| surgery to remove cartilage debris | arthroscopic surgery |
| orthopedic surgery complications | hemorrhage, sublixation, infection, thromboembolism, avascular necrosis, loosening of cemented prosthesis |
| most common joints replaced | hip and knee (shoulder, ankle, wrist and finger joings can also be replaced) |
| After total joint replacement, monitor for: | circulation and sensation in the affected extremity; 6 P's |
| 6 P's (Signs that there isn't adequate circulation) | pain, pressure, parasthesia (tingling), paralysis, palor, pulselessness |
| Client will most likely need a blood _____. | transfusion (may donate their own blood prior to surgery) |
| How to assess patient's pain after surgery: | describe it's location, nature, and severity (may have pain in other joints) |
| Notify surgeon if sudden, severe pain in the surgical area. This could indicate: | prosthesis dislocation |
| How long before physical therapy should you give pain medication to the client? | 30 minutes to 1 hour |
| After hip replacement, keep the leg in a: | position of abduction (to prevent dislocation) |
| After hip replacement, instruct the patient not to cross the legs or flex the hips more than: | 90 degrees |
| After hip replacement, instruct patient to never ___________ when seated. | cross the legs |
| After hip replacement, avoid _________ when seated. A raised _________ should be ued. | bending over; toilet seat |
| After knee replacement, what type of exercisers may be used? | continuous passive motion (CPM) |
| CPM promotes what after knee replacement? | healing and flexibility in the knee. It also increases circulation. |
| Keep wounds __________________ to help prevent infection. | dry and clean |

| Later after surgery, implanted hardware may provide a medium for: | bacteria to grow. |
| Preoperative nursing management: | obtain complete history; assess complications from previous treatment; assist in reducing pain, risk of infection, and increasing mobility; help control anxiety and be sure pt understands post-op instructions |
| Postoperative nursing management includes: | required demonstrations; postsurgery devices; reduce risk for excessive bleeding; review physician orders; flexion of CPM devices and movement; help reduce pain and inflammation; prevent post-op complications |
| Orthopedic surgery client and family teaching: | be sure there is a support system after discharge (help at home); explore kinds of assistance needed (transportation, financial); modifications needed in home (stairs, rugs, etc.); information about home care; referral to home health agency |
| Be sure pt has this when discharging. | Printed discharge instructions that include: activity, physical therapy; symptoms to report |
| Chronic, progressive inflammatory disease | rheumatoid arthritis (RA) |

| RA affects ____________ joints early on and later affects __________ joints. | small; large |
| Onset of RA is characterized by inflammation of: | the synovial tissue. |
| Synovial tissue _____________ and _________ ____________ in the joint space from inflammation. | thickens; fluid accumulates |
| This forms in the joint tissue and breaks down tissue and bone in adjacent cartilage, joint capsule, and bone. | pannus (destructive vascular granulation tissue) |
