First thing we are going to talk about is transplants

most of the time we have to give transplants in whole, so like the entire organ needs to be donated

however, liver, lung and bowel can be transplanted in segment

Q

most of the time patients who have received a transplant are going to be on what ?

so we have to tell them what?

A

these drugs for life

monitor signs of infection because again, its suppressing your bone marrow to prevent rejection, however it surpresses it so you won’t be able to fight off infection

Q

what is the patho behind osteomyelitis ?

A

microorganism enter blood and grow, increasing pressure in bone, leading to ischemia and vascular compromise of periosteum

PICC or central line for 4-6 weeks
27
how long is the chronic antibiotic treatment ?
PICC or central line for 8 weeks or more

morning stiffness for 60mints pain with motion even without motion, it will stiffen up tender, painful, warm
38
the sad part of rheumatoid arthritis is what ?
periods of remission and exacerbation so you can be fine then flare up then be fine and continue like that for life and on top of this, systemic issues
38
what are the 3 contractures names and how does it look like ? describe the image test question
ulnar drift - fingers are drifting away to the ulnar side, or like to the pinky side boutonniere deformity - placing your fingers on the table like your ready to tap on them swan neck deformity - fingers are showing like a swan neck

why do contracures develop for patients who have rheumatoid arthritis ?
if they keep their fingers in a flex position or if they are not moving their fingers
40
how do you diagnose rheumatoid arthritis ?
history and physical exam lab work
41
something important we have to know about rheumatoid arthritis is the lab work. what does ESR ( sedimentation rate ) & CRP ( c reactive protein ) tell us about a patient?
it tells us that if they are present, there is an inflammation going on somewhere in the body, doesn't say what exactly is the cause, but just states that their is inflammation
42
additional about diagnosis, what is so special about ANTI-CCP and ANA for patients with rheumatoid arthritis ?
ANTI-CCP - is the antibody specific to RA ANA - comes up in lab work when we can see an autoimmune reaction is occurring
43
how do we treat rheumatoid arthritis ?
DMARDS ( disease-modifying antirheumatic drugs )
44
how is DMARDS going to help patient with RA?
slow disease progression and decrease rick of joint deformity and erosion
45
what is the medication we need to know about for DMARDS for RA? (3)
methotrexate sulfasalazine (azulfidine) hydroxychloroquine (plaquenil)

how long does it take for methotrexate to start working? when do we start this? what are the side effects (2)?
4-6 weeks early treatment ( beginning phases ) bone marrow suppresion hepatotoxicity
47
typically for sulfasalazine we give it along with hydroxycholorquine for better effectiveness however what do we recommend patient do do?
drink fluids & wear sunscreen
48
plaquenil or hydroxycholorquine has a big risk for developing what ___ and so we have to do this ____
vison loss baseline eye exam and 6-12months eye exam
49
not only are we going to use DMARDS for RA, we can also use another class of medication called ?
tumor necrosis factor inhibitors
50
what is the tumor necrosis factor medication we need to know ?
tofacitinib ( xeljanz )
51
what is the function of tumor necrosis factor medications ?
look for cancer cells and destroy
52
so what is the sad part about giving patients tumor necrosis factor inhibitors?
we are increasing the risk of developing cancer cause we are killing off these cells that do the killing of cancerous cells
53
what do we have to tell patients when they are on tumor necrosis factor inhibitors?
avoid live vaccine monitor for infection
54
what are the 2 live vaccines we tell patients to avoid?
mmr varicella
55
NOTES RA- NURSING MANAGMENT History and exam-focus on family history, joint and systemic symptoms, previous surgeries, medications Nursing diagnoses: Impaired mobility, Chronic pain, Disturbed body image Nonpharmacologic interventions Nondrug therapy Balance of rest and activity Heat and cold application Relaxation techniques Joint protection (see Tables 64-4 and 64-11 in the textbook) Biofeedback TENS Hypnosis
56
its important to tell patients to cluster things together and then have rest periods to avoid the pain temperature sore/swelling - cold pain - warm
57
Alternate rest periods with activity Helps relieve pain and fatigue Avoid total bed rest 8 to 10 hours of sleep plus daytime rest Firm mattress or bed board Encourage positions of extension Avoid flexion positions No pillows under knees Small, flat pillow under head and shoulders Energy conservation Work simplification techniques Pacing and organizing Use of carts Joint protective devices Delegation Occupational therapy Assistive devices
58
what's cold used for RA typically? what is heat usually helped for in ra?
swelling/sore relieve chronic stiffness remember dont use more than 10-20mintues

after the acute infection, after this they progress into the asymptomatic infection which really no symptoms or any signs of infection however, if left untreated or looked at, what happens?
aids after 10 years
84
however not everyone is asymptomatic after the inital acute infection, some become symptomatic what is going on for their CD4 T cells?
declines closer to 200 cells and symptoms become 100x more worse than before

what are some opportunities infections that can occur with patients who have HIV?
oral hairy leukoplakia thrush kaposia sarcoma honestly anything
86
what are diagnostic study for hiv?
CD4 cell count viral load
