TEST 2 MOD 7 WINKS Flashcards
RA joint deformities
Rheumatoid arthritis
A, Early pathologic change is rheumatoid synovitis.
Synovium becomes inflamed. Lymphocytes and plasma cells increase greatly.
B, Over time, articular cartilage destruction occurs, and vascular granulation tissue
grows across the cartilage surface (pannus) from the edges of the joint.
Joint surface shows loss of cartilage beneath the extending pannus, most marked
at joint margins.
C, Inflammatory pannus causes focal destruction of bone.
Osteolytic destruction of bone occurs at joint edges, causing erosions seen on x-rays.
This phase is associated with joint deformity.
OA assessment findings, treatments, complications, joint deformities, medications
Osteoarthritis: Degeneration of articular cartilage over time caused by wear and tear
Early disease
Synovitis may occur when phagocytic cells (WBCs) attempt to rid the joint of small pieces of cartilage torn from the joint surface.
Results in pain and stiffness early in the disease process.
Osteoarthritis (OA) is a slowly progressive noninflammatory disorder of the
diarthrodial (synovial) joints.
A is not a normal part of the aging process, but aging is one risk factor for disease
development.
Later disease
Pain is primarily due to loss of articular cartilage and bony joint surfaces rubbing against each other.
Osteophytes form around the periphery of the joint by irregular overgrowths of bone.
With time, thickening of subarticular bone (cysts) occurs, caused by constant friction of the
2 bone surfaces.
Osteophytes form around the periphery of the joint by irregular overgrowths of bone. (bumpy bone)
Joint pain (early)
Diminishes after rest
Intensifies after activity
Joint pain (advanced)
Pain occurs with slight motion or even at rest
Morning stiffness for less that 30 minutes or less
OA usually affects joints on 1 side of the body (asymmetrically) rather than in pairs.
Fatigue, fever, and organ involvement are not present in OA.
This is an important distinction between OA and inflammatory joint disorders, such
as rheumatoid arthritis.
Symptoms are aggravated by temperature change and humidity
Crepitus
Joint enlargement
Heberden’s Nodes
On the Distal Interphalangeal Joints (DIP joints)
Bouchard’s Nodes
On the Proximal Interphalangeal Joints (PIP joints)
Indicative of osteophyte formation
Often red, swollen, and tender
Although they usually do not cause significant loss of function,
the visible deformity may bother the patient.
Knee
Joint misalignment common due to cartilage loss
Hip
One leg may become shorter from a loss of joint space
For example, the patient becomes bowlegged (varus deformity) in response (knees bent out)
to medial joint arthritis.
Lateral joint arthritis causes a knock-kneed appearance (valgus deformity). (knees bent in)
Bone Scan, CT scan, MRI
To detect early joint changes
X-rays
Progressive OA results in joint space narrowing, bony sclerosis, and osteophyte formationX-ray changes do not always reflect the degree of pain the patient has.
Despite strong x-ray evidence of disease, the patient may be relatively
free of symptoms. Another patient may have severe pain with only slight
x-ray changes.
Joint rest: Avoid immobilization for more than 1 week because of the risk for joint
stiffness with inactivity.
Closed
Skin over the fractured area remains intact
types and treatments
simple
Skin over the fractured area remains intact
types and treatments
Open
Bone is exposed to air through a break in the skin The skin is broken and bone exposed, causing soft tissue injury. increase infection risk
types and treatments
Compound
Bone is exposed to air through a break in the skin The skin is broken and bone exposed, causing soft tissue injury. increase infection risk
types and treatments
Complete
Bone completely separated by a break into two parts A fracture is complete if the break goes completely through the bone.
types and treatments
Incomplete
Partial break in the boneAn incomplete fracture occurs partly across a bone shaft,
but the bone is still intact.
An incomplete fracture is often the result of bending or crushing
forces applied to a bone.
types and treatments
Displaced
The 2 ends of the broken bone are separated from each other and out of their normal positions
types and treatments
Nondisplaced
The bone fragments stay in alignment
types and treatments
Fracture nursing care
Patient’s dietary requirements must include
Ample protein (1 g/kg of body weight)
Vitamins (B, C, D)
Calcium
Phosphorus
Magnesium
Adequate fluid intake
2000 to 3000 mL/day
High-fiber diet with fruits and vegetables
Constipation can be prevented by
Increased activity
High fluid intake (>2500 mL/day)
Diet high in bulk and roughage
Warm fluids, stool softeners, laxatives, or suppositories may be necessary.
Prevent constipation by increasing patient activity.
Maintain high fluid intake (more than 2500 mL/day unless contraindicated
by the patient’s health status) and a diet high in bulk and roughage
(fresh fruits and vegetables). If these measures are not effective in continuing
the patient’s normal bowel elimination pattern, give stool softeners, laxatives, or
suppositories. Maintain a regular time for elimination to promote bowel regularity.
Renal stones can develop from bone demineralization due to reduced mobility.
Hypercalcemia from demineralization causes a rise in urine pH and stone formation
from calcium precipitation. Unless contraindicated, maintain a fluid intake of 2500
mL/day to decrease the risk for stone formation.
Rapid deconditioning of cardiopulmonary system
Result of prolonged bed rest
Results in
Orthostatic hypotension
Decreased lung capacity
Reinforce physical therapist’s instructions.
Nurse may need to assist patient with lower extremity dysfunction.
Usually start mobility training when able to sit in bed, dangle feet over side

Open reduction
Correction of bone alignment through surgical incision
Includes internal fixation with use of wires, screws, pins, plates, intramedullary rods, or nails
The main risks of open reduction are infection, complications associated
with anesthesia, and effects of preexisting medical conditions (e.g., diabetes).
However, open reduction internal fixation (ORIF) facilitates early ambulation,
thus decreasing the risk for complications related to prolonged immobility.
Traction, casting, splints, or orthoses (braces) may be used after reduction
to maintain alignment and immobilize the injured part until healing occurs.
External Fixation
Metallic device
Composed of metal pins inserted into bone and attached to external rods
External device holds fracture fragments in place similar to a surgically implanted internal device.
Infection control is critical.
Infection signaled by
Exudate
Erythema
Tenderness
Pain
Instruct patient and family on meticulous site care.
traction
Closed Reduction
Nonsurgical, manual realignment of bone fragments to previous anatomic position
Traction and countertraction manually applied to bone fragments to restore position, length, and alignment
Closed reduction is usually done while the patient is under local or
general anesthesia.
Traction, casting, splints, or orthoses (braces) may be used after reduction
to maintain alignment and immobilize the injured part until healing occurs.
Description
The exertion of a pulling force applied in two directions to reduce and immobilize a fracture
Force exerted on distal bone fragment to align it with the proximal fragment
Countertraction (opposite direction) is usually supplied by the patient’s own body weight or weights in the opposite direction
Provides proper bone alignment and reduces muscle spasms
Two most common types
Skin
Skeletal
Traction must be maintained continuously.
Keep the weights off the floor and moving freely through the pulleys.
Do not interrupt weights applied
Skin should be inspected AT LEAST every 8 hours for inflammation and irritation
Monitor color, motion, and sensation of the affected extremity
Monitor the insertion sites for redness, swelling, or drainage
Provide insertion site care as prescribed
casting
Provide immobilization of bone and joints after a fracture or injury
Cast materials are natural, synthetic acrylic, fiberglass-free, latex-free polymer, or a hybrid of materials.
A cast generally immobilizes the joints above and below a fracture.
This restricts tendon and ligament movement, thus assisting with joint stabilization
while the fracture heals.
The 2 most common cast materials are natural (plaster of Paris) and fiberglass.
Fiberglass casts are most often because they are lighter, relatively waterproof, and
longer wearing than plaster of Paris.
Keep cast and extremity elevated
Handle a wet cast with the palms of the hand until dry
Examine the skin and cast for pressure areas
Monitor the extremity for circulatory impairment and signs of infection
Explain the importance of elevating the extremity above heart level to promote
venous return and applying ice to control or prevent edema during the initial phase.
Tell the patient not to scratch or place anything inside the cast because this may
cause skin injury and infection.
For itching, direct a hair dryer on a cool setting under the cast.
