Step-by-step explanation:
The technician who is capable of monitoring blood pressure and temperatures under the supervision of a licensed nurse is most likely a Certified Nursing Assistant (CNA). CNAs are trained to assist nurses with various care tasks, such as taking vital signs which include blood pressure and temperature measurements. On the other hand, a Medical Technologist primarily works in a lab setting analyzing various body fluids, a Licensed Practical Nurse (LPN) has more advanced training and can perform more complex procedures, and a Phlebotomist is specialized in drawing blood for tests, transfusions, research, or blood donations.
