Contamination in a medical setting refers specifically to the presence of harmful microorganisms on objects or surfaces that were previously considered clean or disinfected. When an item that has been disinfected becomes soiled with microorganisms, it is then deemed contaminated, which can pose a risk for infection or disease transmission. This understanding is crucial in maintaining safe and hygienic practices within medical environments.

In contrast, the other options do not accurately represent the concept of contamination. The use of only sterile items indicates a clean environment rather than contamination. An aseptic condition refers to the complete absence of pathogenic microorganisms, which is the opposite of contamination. The absence of body fluids describes a potentially sterile condition rather than addressing the presence of microorganisms directly. Thus, option C is the most aligned with the definition of contamination in a medical context.
