Which category of work duties includes the proper puncturing of a patient's skin?

The correct category encompassing the proper puncturing of a patient's skin is associated with procedures. In the context of phlebotomy, a procedure refers to a specific method or series of steps taken to carry out a task, such as drawing blood. Proper skin puncturing is a critical procedural skill that ensures patient safety and comfort while achieving accurate blood sampling.

Procedural duties in phlebotomy include various techniques and practices necessary for successful venipuncture, including site selection, sterilization, and the handling of equipment. Mastery of these techniques is essential for phlebotomy technicians, as improper application could result in complications for the patient, inadequate samples, or both.

Patient information generally pertains to gathering and recording personal details and medical histories, while patient care involves providing appropriate support and reassurance to patients during medical procedures. Equipment refers to the tools and supplies used during procedures, but it does not encompass the actions taken to perform a procedure itself. Thus, procedural tasks encapsulate the specifics of how to safely puncture the skin and collect samples, making it the correct choice in this context.
