Final Exam Flashcards
generalized osteoporosis
primary
secondary
- a bit longer and more complex
- multiple structures
- causes: anemic states, drugs (steroids/heparin), dietary deficiency (scurvy, malnutrition, calcium
- both primary and secondary fall under this.Primary occurs in postmenopausal woman and in **70-80 year old men. Secondary results from past medical conditions. Prolonged mobility from spinal cord damage
- ***long term corticosteroid use
regional osteoporosis
- *Also caused localized
- *Affects 1 bone or area
- *Traumatic fracture
- Characterized by arthralgia which migrates between the weight bearing joints of the lower limbs
- Causes: immobilization and disuse, reflex sympathetic dystrophy syndrome, transient regional osteoporosis (transient regional osteoporosis of the hip, regional migratory osteoporosis
- ***Decreased mobility for longer than 8-12 weeks can result from this type
modifiable risk factors for osteoporosis
smoking
-more than 2 - 3 drinks alcohol
little to no exercise
High volume intake of carbonated drinks
nonmodifiable risk factors
gender small framed/thin menopause **Protein deficiency **estrogen **Chronic low calcium or vitamin d
diagnostic test for osteporosis
- Doctor will order bone density scan - measures bone mineral density
- BMD assessment by a DXA (dual energy xray absorptiometry) - measures bone mineral density
- Ct- can measure volume of bone density and strength of vertebral spine
pharmacological management for osteomyeltis
4-6 weeks antimicrobical therapy more than 1 prescribed given at specific intervals to maintain therapeutic serum levels zoysn central line
non pharm management for osteomyelitis and stump
mrsa precautions
stump elevation
line prone for 15 mins four times a day
hypobaric oxygen therapy
E.B. asks you “What do they do with my leg after it is removed?” How do you respond?
It’s your choice on what you wish to happen after it is amputated. Some cultures decide to have the amputation stored for later burial or buried immediately. Other times, it can be donated for scientific research, or sent to biohazardous waste and is cremated.
Culturally component nursing care
interventions for healing a stump
- Promote mobility as tolerated
- Assess for adequate tissue perfusion and hemorrhaging (pinkish color, warm but not hot)
- Vital signs, specifically pulses near the amputation site
- Monitor and treat pain
- Assess psychosocial needs (body image issues)
- Maintaining a healthy diet
- Exercise
phantom limb pain
Phantom limb pain, although the limb is gone the nerve endings at the site of the amputation continue to send pain signals to the brain that make the brain think the limb is still there. Finding a treatment to relieve phantom pain can be difficult. Doctors usually begin with medications such as over-the-counter pain relievers, antidepressants, anticonvulsants, narcotics, NMDA receptor antagonists. Doctors may then add noninvasive medical therapies such as mirror box, acupuncture, repetitive transcranial magnetic stimulation, spinal cord stimulation. Surgery may be an option if other treatments haven’t helped, the only surgical option is brain stimulation.
four major complications of acute fractures
infection
acute compartment syndrome
vte
fat embolism
infections cm fracture
fever, high WBC, chills and sweats, SOB, inflammation, swelling
acute compartment syndrome
pain due to reduced perfusion: pain severe despite being medicated, which causes further ischemia. Sensory perception deficits and paraesthesia. Pale color due to low perfusion and weak pulses. Cyanosis, tingling, and numbing can occur if not treated.
vte cm fracture
SOB, rapid breathing, chest pain upper rib cage, heart rate increases, leg pain or tenderness of the leg or calf, edema to the LE
fat embolism cm fracture
Dyspnea, increased RR, decreased o2 sat, tachycardia, confusion, chest pain
delayed union
Fracture takes longer than usual to heal (longer than 6 months)
nonunion
things to help
Fracture that never heals
- Electric bone stimulation and bone grafting can treat
- Low intensity pulsed ultrasound can promote healing to treat
- Can occur more frequently in older adults due to impaired healing process
- Can cause immobilizing deformity of the bone involved
malunion
Fracture heals incorrectly
Can cause immobilizing deformity of the bone involved
nonpharmacological interventions osteoarthritis
**Rest
**Balanced rest with exercises
Elevation ( only small pillows) slightly bent if not created flexion contractures
Diet
**Loose weight
**Brace (assistive devices)
**Thermal modalities and or ice ( whichever provides more relief)
**Keep extremity in function/ dependent positon
- cyrotherapy
exercise plan osteoarthritis
- Start with short walks (aerobic), then make the walks longer distances or a quicker pace. Pay close attention to how the joint feels and what level of pain they are experiencing.
- National guidelines recommend 150 minutes per week (spaced out) of moderate intensity physical activity, plus 2 strength training sessions/ week. Examples include: brisk walking, slow biking, general gardening, and ballroom dancing
pain meds for osteoarthitis
tylenol, lidocaine, tramadol, glucosamine with chondroitin
rheumatoid factor clinical significance
Rheumatoid factor: measures the presence of unusual antibodies of the immunoglobulins G (IgG) and M (IgM) types that develop in a number of connective tissue diseases: many patients have an RA have a positive titer
antinuclear antibody clinical significance (RA)
- measures the titer of a group of antibodies that destroy the nuclei of cells and cause tissue death in patients with autoimmune disease.
- If this test result is positive (a value higher than 1:40), various subtypes of this antibody are identified and measured.
invasive diagnostic of ra
arthrocentesis
- invasive diagnostic procedure that may be used for patients with joint swelling caused by excess synovial fluid (effusion). Done as a diagnostic procedure. Can be done as a treatment modality
- The provider inserts a large-gauge needle into the joint (usually the knee) to aspirate a sample of synovial fluid and to relieve pressure caused by excess fluid. The fluid is analyzed for inflammatory cells and immune complexes, including RF. Fluid from patients with RA typically reveals increased WBCs, cloudiness, and volume.
- Patient nursing considerations are to teach the patient to use ice and rest the affected joint for 24 hours after arthrocentesis. Often the primary health care provider will recommend acetaminophen as needed for discomfort.
bucks traction
Buck’s traction is meant to keep the leg in an extended position by means of a longitudinal skin traction applied in one direction with a single pulley. This system is meant to help with fractures, realigns bones, helps correct contractures or deformities and is meant to immobilize the knee
bucks traction nursing considerations
- ensure that the weight bag is hanging freely, to not have the bag rest on the floor, if the rope becomes frayed, it must be replaced, the nurse should ensure that the rope is on the pulley track, and the nurse should make sure the bandages are free from wrinkles.
- Pulling force, pulls bones apart, decrease inflammation and destruction because bones are not being rubbed against
- (Buck) traction may be applied before surgery to help decrease pain associated with muscle spasm.
- Don’t remove weights until surgery or physician order
