NURS 2055 Inflammatory and Structural Heart Disorders
Test With Complete Solution
3 layers of heart wall - ANSWER - endocardium: innermost layer and heart
valves
- myocardium: muscle layer
- pericardium: sac that encloses the heart
Endocarditis - ANSWER inflammation INSIDE the heart
Why does endocarditis occur - ANSWER - pathogens enter the bloodstream
and form vegetative lesions, which enlarge and can disrupt blood flow
- heart valves cannot fully close
Endocarditis: causes - ANSWER infection (bacteria, viruses, or fungi)
Endocarditis: risk factors - ANSWER IV drug use, valve replacement/repair,
valve disease, recent dental procedures, invasive procedures, URT infections
Why can recent dental procedures cause endocarditis - ANSWER - 50% due
to poor hygiene
, - mouth is vascular and easier for bacteria to get to heart
Endocarditis: complications - ANSWER embolizations of vegetations can
impact oxygen flow to other organs (ex// spleen, lungs, kidney, or brain)
Pericarditis - ANSWER inflammation OUTSIDE the heart (scaring and fibrosis)
Why does pericarditis occur - ANSWER heart gets compressed & cardiac
function is restricted
Pericarditis: causes - ANSWER - infection (bacteria, viruses, TB)
- myocardial and pericardial injury
- connective tissue diseases
- autoimmune disorders
Pericarditis: risk factors - ANSWER end stage renal disease, uraemia, trauma,
surgery, or recent infection
Pericarditis: complications - ANSWER - pericardial effusion (fluid build up in
the pericardial cavity)
- cardiac tamponade (accumulation of fluid compresses the heart)
