Which procedures require the use of sterile technique?

The use of sterile technique is crucial in environments where the risk of infection is heightened, particularly during surgical procedures and invasive interventions. This approach is designed to eliminate or minimize the presence of pathogens on instruments and in the areas where procedures are conducted.

Surgical procedures involve making incisions into sterile areas of the body, such as when performing operations on internal organs or systems. Invasive interventions could include catheter insertions or spinal taps, where equipment may come into contact with potentially sterile body cavities. Sterile techniques ensure that these areas remain free from contaminants, thus reducing the risk of surgical site infections and other complications that can arise from introducing bacteria or other pathogens into the body.

Routine care and examinations, ambulatory care procedures, and administering oral medications do not typically require the same level of sterility. In these contexts, the procedures may still adhere to cleanliness standards, but they do not necessitate a sterile field or equipment, as they typically involve external surfaces or less invasive actions. Therefore, option A is the correct choice for procedures that specifically demand sterile technique.
