NCLEX Question of the Day
Review the question, check the correct answer, and read the rationale before tomorrow's prompt arrives.
When educating a patient on ways to reduce the risk of infection, which type of microorganism should the nurse emphasize as a normal part of the body's flora and not typically harmful?
-
Pathogenic bacteria that cause diseases.
-
Viruses that lead to infections like the flu.
-
Parasites that can cause complex diseases.
-
Correct answer Resident flora that usually exist on the body without causing harm.
Rationale
Resident flora are the microorganisms that normally reside on the body, often without affecting individual's health. They are different from pathogens, such as certain bacteria, viruses, and parasites, which are associated with disease. The presence of resident flora can, under certain circumstances, confer benefits such as competing with pathogens for nutrients and space, thereby providing a form of natural defense against infection.
