The nurse educator, who is teaching a class on sexually transmitted infections, recognizes that teaching has been effective when students indicate which statement is true about the difference between colonization and infection? "Colonization becomes infection when the host and organism interact." "Colonization and infection are interchangeable terms used to describe a bacterial invasion." "Colonization results in symptoms such as redness and swelling, infection results in fever." "Both colonization and infection require treatment with different antibiotics."

"Colonization becomes infection when the host and organism interact."

A client was unaware that intestinal flora are beneficial, stating, "I thought all bacteria were bad." Which is the nurse's most accurate response? "An interaction such as this is called commensalism: The colonizing bacteria acquire nutritional needs and shelter, and the host is able to keep their numbers under control." "The term 'mutualism' is applied to an interaction in which the microorganism and the host both derive benefits from the interaction." "There's a parasitic relationship by which the bacteria benefits but there's a minimal effect on the host's health."

"I'll make sure the doctor is made aware that you'd like your son to have a course of antibiotics." "Infection is not the same as inflammation. What your son has is inflammation." "In children who are previously healthy, inflammation and infections usually resolve without the need for drugs." "This is a local inflammatory response to the insect bite; it is not an infection so antibiotics will not help."
