The complication the nurse will constantly observe for is Systemic emboli.
The main issue is emboli; those that originate in the right heart chambers will end up in the lungs, while those from the left chamber may move wherever in the arteries. Heart murmurs, fever, and night sweats might be present, but they don't necessarily signify an emboli issue. Although CHF could ensue, this is not as serious as emboli.
When bacteria or other pathogens get into the bloodstream and go to the heart, endocarditis happens. The germs then adhere to heart tissue or damaged heart valves. Endocarditis is an infection that can be lethal that affects the inner lining of the heart's chambers and valves. We refer to this lining as the endocardium.
