Immobilization, reduction, pain reduction, and reducing swelling.
38
What are the types of traction?
Bucks (skin) and skeletal.
39
What is Bucks traction?
Short term (48-72 hours) while the patient waits for surgery or uncontrolled pain; uses 5-10 pounds.
40
What is skeletal traction?
Long term; uses pins inserted into the bone and skin above and below the site of the fracture; uses 25-40 pounds and weights should hang free.
41
What is cast care?
Frequent neurovascular checks (usually moving toes/fingers and cap refill), pain management, and monitoring for infection.
42
What are hot spots in cast care?
Areas where warmth or heat can be felt through the cast.
43
What is internal fixation?
Placement of hardware into the bone to stabilize and keep it together.
44
What are the risks for internal fixation?
Rejection, infection, and loss of range of motion (ROM).
45
What is external fixation?
A device placed into the fracture site with the main hardware on the outside; used for patients with open fractures waiting for surgery.
46
What are the risks for external fixation?
Infection and fall risk.
47
What factors affect bone healing?
Age, circulation, smoking, and co-morbidities.
48
What are the causes of impaired healing?
Delayed union, nonunion, and malunion.
49
What is delayed union?
Prolonged healing.
50
What is nonunion?
A nonhealed fracture after 4-6 months; very common in smokers.
51
What is malunion?
Malalignment of a healed fracture; fixed by rebreaking the bone and realigning the fracture.
52
What is osteomyelitis?
Infection in the bone, often starting within the patient and making its way out.
53
What are the risk factors for osteomyelitis?
Open wound (not just fractures), soft tissue injury, internal fixation (foreign substance in body), and urinary tract infection (bacteria travels).
54
What are the signs and symptoms of local osteomyelitis?
Bone pain, swelling, tenderness, and warmth.
55
What are the signs and symptoms of systemic osteomyelitis?
Fever and chills, drainage from the site, restlessness, nausea, malaise, and increased WBC.
56
What are the diagnostics for osteomyelitis?
Cultures (wound and blood), labs (CRP and WBC), and X-ray (will show infection).
57
Which vital sign is the most important related to infection?
Temperature.
58
What are antibiotic beads?
Placed where infection is occurring; the beads slowly release the antibiotic into the wound.
59
What is compartment syndrome?
Increased pressure within a compartment.
60
What is ischemia?
Lack of blood supply.
61
What are the assessment findings with compartment syndrome?
Pain, paresthesia, pulselessness, paralysis, pallor, and pressure.
62
How can compartment syndrome be prevented?
Frequent neurovascular checks, pain assessment, and elevation.
63
What should be done with suspected compartment syndrome?
Notify provider, monitor urinalysis output, do not elevate above heart, and do not use cold compresses.
64
Why do you check urinary output with suspected compartment syndrome?
Myoglobin in the urine shows muscle breakdown.
65
What is the treatment for compartment syndrome?
Fasciotomy.
66
What is a fasciotomy?
Surgical decompression; left open with a risk for infection.
67
What are the risks for venous thromboembolism?
Hip fracture, pelvic fracture, hip or knee replacement, and decreased mobility.
68
What is fat embolism syndrome?
Fat globules make their way to the lungs, similar to a pulmonary embolism.
69
What bones are affected by fat embolism syndrome?
Long bones (hip, femur, ribs, tibia, pelvis).
70
What are the signs and symptoms of fat embolism syndrome?
Confusion, restlessness, petechiae on the chest, respiratory distress, and feeling of doom.
71
How can fat embolism syndrome be prevented?
IV fluids and fracture immobilization (less likely the fat will get into the systemic system).
72
Why is fat embolism syndrome dangerous?
There are no drugs like anticoagulants to break the fat globule apart.
73
Why are hip fractures more common in women?
Higher risk for osteoporosis.
74
What are the signs and symptoms of a hip fracture?
Pain, deformity (leg is shorter than the other), and externally rotated.
75
What are the nursing priorities for a hip fracture?
Hydration, respiratory support, neurovascular checks, pain control, and vital signs.
76
What labs would be needed before hip fracture repair?
CBC, WBC, and type and cross.
77
What changes will there be to vital signs if a patient is bleeding after hip fracture repair?
Low BP, increased HR, and decreased O2.
78
What is arthroplasty?
Replacement of a diseased or injured joint with mechanical devices.
79
What are the reasons for arthroplasty?
Osteoarthritis, rheumatoid arthritis, and fractures.
80
What joints are the most commonly replaced?
Knees and hips.
81
What is a partial replacement?
Only replaces the ball.
82
What is a total replacement?
Both the ball and socket are replaced.
83
What is an anterior hip replacement?
Incision in the front; recover faster but is less common.
84
What is a posterior hip replacement?
Most common type; incision in the back.
85
Why is a urinalysis important before joint replacement?
To check for a UTI; if present, the risk of infection increases significantly.
86
How can you know a patient has a UTI?
Foley catheter puts them at risk, delirium, bloody urine, increased frequency and urgency, odor, and sediment in urine.
87
What is post-operative care for joint replacement?
Monitor for bleeding, monitor for infection, activity (out of bed on day 1), pain management (narcotic analgesics), anticoagulation (until they are completely weight-bearing), and incision care (teach signs of infection).
88
What are the hip replacement precautions?
Need a pillow between legs at all times, no bending at the waist, and no crossing legs.
89
What is a CPM machine?
A machine used after knee replacement that flexes and extends the leg for range of motion.
90
What medication is used to treat VTE?
Anticoagulation enoxaparin (heparin substitute) given subcutaneously twice a day.
