Which of the following terms is used to describe a procedure characterized by its need for physical entry into the body?

The term that describes a procedure characterized by its need for physical entry into the body is "invasive." Invasive procedures involve techniques that penetrate the skin or enter a body cavity, which typically raises a greater risk of infection and requires more intensive care than non-invasive procedures. Examples of invasive procedures include surgeries, biopsies, and catheter insertions, where an instrument or device is introduced into the body for diagnostic or therapeutic purposes.

In contrast, therapeutic procedures focus on treatment but do not necessarily require physical entry, while preventive procedures are designed to avert diseases or conditions before they occur, often through vaccinations or screenings. Supportive procedures are aimed at providing relief or support but do not imply invasive methods. This differentiation further highlights how invasive procedures are distinct due to their direct interaction with body interiors.
