Which of the following is NOT a responsibility of phlebotomists in patient care?

Phlebotomists are primarily trained to perform blood collection and related activities in a clinical setting. Their responsibilities focus on ensuring that the process of drawing blood is safe, efficient, and comfortable for the patient. This includes reassuring patients who may have anxiety about needles, answering any questions they may have regarding the procedure, and monitoring patients during the blood draw to ensure they are not experiencing any adverse reactions.

Assisting with complex medical procedures is outside the scope of a phlebotomist's typical duties. Complex medical procedures often require advanced training and expertise that phlebotomists do not possess. Therefore, this option accurately reflects a responsibility that is not part of the phlebotomist's role in patient care.
