25
septic arthritis
invasion of joint cavity with microorganisms resulting in hematogenous seeding of joint, can be caused by gonorrhea, large joints frequently involved
26
s/s of septic arthritis
severe pain, erythema, swelling, fever, chills
27
diagnostics for septic arthritis
arthrocentesis to do a culture of synovial fluid
28
tx for septic arthritis
antibiotics promptly to prevent joint destruction, monitor joint inflammation, pain, and fever
29
lyme disease
spirochetal infection transmitted by the bite of an infected deer tick, not transmitted person to person, occurs most during the summer
30
s/s of lyme disease
erythema migrans (EM) is a skin lesion that occurs at the site of the tick bite within 2-30 days of exposure, low grade fever, stiff neck, swollen lymph noteds, migratory joint and muscle pain, untreated can migrate to- CNS, heart, and joints
31
diagnosis of lyme disease
based on clinical manifestations (EM lesion in particular) and a history to endemic area, ELISA test and western blot to confirm
32
tx of lyme disease
tx with antibiotics such as Doxycycline, no vaccine available
33
where do you commonly find lyme disease?
maryland to massachusetts, wisconsin and minnesota, california and oregan
34
gout
increase in uric acid production, underexcretion of uric acid, increased foods in purines, recurrent attacks of acute arthritis
35
causes of gout
drugs that increase cell death such as chemotherapy, thiazide diuretics, postmenopausal women, immunosuppresant pt, obesity in men, excessive alcohol, prolonged fasting
36
what foods are high in purine?
shellfish, lentils, asparagus, spinach, beef, chicken, pork
37
acute s/s of gout
arthritis may occur in one or more joints, but less than 4, joints dusky or cyanotic, tender, inflammation of great toe, subsides in 2-10 days
38
chronic s/s of gout
multiple joint involvement and visible deposits of sodium urate crystals (tophi), chronic inflammation, cartilage destruction may precede OA, kidney or urinary tract infection
39
diagnostics of gout
uric values 6+, synovial fluid aspiration to eliminate possibility of other diseases
40
tx of gout
Colchicine, NSAIDs for pain management, avoid alcohol and purine foods, adequate hydration
41
Uloric
given for long term gout
42
nursing management for gout
supportive care of the inflamed joints, avoiding precipitating factors that can cause the disease- excess calories, alcohol, purine foods, starving, aspirin, diuretics, MI
43
systemic sclerosis
connective tissue disorder, degenerative, occassionally inflammatory changes in skin, blood vessels, internal organs, more common in african americans women, overproduction of collagen
44
causes of systemic sclerosis
exposure to coal, plastics, and silica dust
45
CREST
s/s of systemic sclerosis: calcinosis, raynaud's phenomenon (abnormal blood flow in response to cold or stress), esophageal dysfunction, sclerodactyly (tightening of skin on fingers and toes), telangiectasia (red spots on hands, forearms, palms, face, lips)
46
raynaud's phenomenon
most common symptom in limited systemic sclerosis (more common disease), decreased blood flow in response to cold, cyanosis, and then erythema, numbling and tingling
47
limited cutaneous disease
more popular systemic sclerosis, skin thickening does not extend above elbows or above the knee
48
diffuse cutaneous disease
less popular systemic sclerosis, skin loses elasticity and becomes taut and shiny producing expressionless faces with tightly pursed lips
49
diagnostic studies for systemic sclerosis
mild anemia, SCL-70 gene, lab findings generally normal
50
tx for systemic sclerosis
no long term effects, attempt to prevent or treat secondary complications of involved organs, calcium channel blockers for early tx
51
nursing management for systemic sclerosis
don't have finger sticks because of poor circulation and poor healing of fingers, use moist heat to promote flexibilty of hands and feet, lotions must be rubbed in for long time, small frequent meals to reduce dysphagia, oral hygiene
52
polymyositis and dermatomyositis
diffuse, idiopathic, inflammatory myopathies that produce bilateral weakness, PM is more serious
53
s/s of polymyositis and dermatomyositis
weight loss, gradually weakness of muscles, discomfort and tenderness of muscles is uncommon, dysphagia and dysphonia (hoarse voice)
54
s/s of dermatomyositis
violet colored or cyanotic edema around eyelids, violet colored (heliotrope), cyanotic, or erythematous rash with edema around eyelids
55
diagnostics for polymyositis and dermatomyositis
confirmed by MRI, EMG findings (bizarre high discharges and positive spikes at rest), muscle biopsy reveals necrosis, degeneration
56
tx for polymyositis and dermatomyositis
high dose corticosteroids, immunosuppresives, massage, passive movement
57
sjogren's syndrome
autoimmune that targets moisture producing glands, lymphocytes attack and damage lacrimal and salivary glands
58
s/s of sjorgren's sydrome
gritty sensation in eyes, burning and blurred vision, photosensitivity,
59
tx of sjorgren's sydrome
instillation of preservative free tears such as cyclosporine (Restasis), increased fluids with meals, dental hygiene, increased humidity at home
60
fibromyalgia syndrome
chronic pain with multiple tender points, nondegenerative, nonprogressive, noninflammatory
61
s/s of fibromyalgia
nonrestorative sleep, morning stiffness, IBS, anxiety, widespread burning pain and improves through course of day
62
diagnostics for fibromyalgia
muscle biopsy may reveal nonspecific moth-eaten appearance of fiber atrophy, pain experienced in 11 of the 18 tender points, widespread pain for 3 months
63
tx for fibromyalgia
antidepressants and muscle relaxants, long acting opioids not recommended, benzo with ibuprofen to treat anxiety as well as muscle spasms
