A syststemic inflammatory disease that sometimes follows Group A streptococcal infection.
What structures are affected with rheumatic carditis?
layers affected are endocarditis, myocarditis, and pericarditis, also heart valves are, most commonly MITRAL
When WBC's migrate to the endocardium causing inflammatory debris to accumulate around the leaflets which cause fibrous tissue to fuse of thicken and shorten (chordae tendinea)
vegetations (valves loose abilityto open fully or close tightly)
rheumatic fever is a complication of which infections?
who usually gets rheumatic fever?
in children 2 to 3 weeks
Inflammation of the layers of the heart is called?
inflammation of more then one joint is called?
involuntary grimacing and an inability to use skeletal muscles in a coordinated manner is called?
fever for several weeks, heart rate is rapid,or abnormal, erythema marginatum (red spotty rash)polyarthritis, poss nodules, chorea are symptoms of what?
what does a heart murmur suggest?
which diagnostic findings help diagnose rheumatic fever?
no specific lab avail.....instead they can do a antistreptolysin o titrate, sed rate, CRP to check inflammation response. EKG and echo may show cardiac changes/damage.
name 3 meds used to treat rheumatic fever
1. PCN drug of choice
2. azithromycin-if allergy to pcn
3.vancomyocin if allergy to pcn
there are others so drugs may vary. most important is Penicillin
describe the nursing management for a patient with rheumatic fever
Administer drug therapy, monitor for therapeutic an adverse effects, encourage rest or reduce activities, do cardiac assessment, nutrition considerations
Inflammation of the inner layer of the heart tissue as a result of an infectious microorganism is called?
Name 2 bacteria that most frequently causes bacterial endocarditis
streptococcus viridans and staphylococcus aureus
Who are at risk for getting infective endocarditis?
pts with hx of rheumatic carditis, pts who have nonrheumatic valve disease or artificial heart valves, repaired congential heart defects, a prolapsed mitral valve or cardiomyopathy. IV drug users, immunosuppressed or pt with central lines
How do vegetations adversely affect the heart?
the microorganisms bury themselves in the vegetative mass making them difficult to destroy.
which valve is mostly affected with vegetations?
what would happen if vegetations break off?
causes an emboli that then may occlude small vessels and interfere with an organs blood supply
