The first reason for conducting a critical appraisal on a particular study is to determine whether there are ...

When these microorganisms get into the respiratory system they cause lung infection which is referred to as ventilator-associated pneumonia (VAP). In preventing this infection, it is important that nurses adopt best practices to reduce the incidence of VAP and provide quality care that is aimed at improving the ...
