The nurse is teaching peers about infection. Which of the following statements made by the nurse is accurate?
1. "Microorganisms are always harmful to the human organism."
2. "An infection is defined as an invasion of the body by any microorganism."
3. "Infections can be caused by a virus, bacteria, or fungi."
4. "Antibiotics are effective for all infections."
3
Rationale 1: Infections can be caused by a virus, bacteria, or fungi. Microorganisms are not always harmful, and some organisms are important to normal functioning of the body. An infection is defined as an invasion of the body by a disease-causing organism, not just any organism. Antibiotics are effective for bacteria, but are not effective against viruses or fungi.
