Final answer:
Inserting an IV catheter and administering IV medication are actions likely outside the scope of practice for patient care technicians/nurse aides, while monitoring for signs of infection and adjusting the IV flow rate under supervision might be permitted.
Step-by-step explanation:
The scope of practice for healthcare providers can vary depending on their role and the regulations of the state or country in which they practice. If you are a patient care technician/nurse aide and one of your assigned patients needs an IV (intravenous) line for nutrients, the actions you are certified to do might include monitoring for signs of infection at the IV site and possibly adjusting the IV flow rate as needed, if you are trained and permitted to do so under the direct supervision of a registered nurse. However, inserting the IV catheter and administering IV medication typically fall outside the scope of practice for nurse aides and are usually responsibilities of a registered nurse or a physician. When inserting central IV lines, professionals, including doctors and registered nurses, often use a checklist to ensure that the procedure is done safely and correctly, much like the one implemented by Dr. Pronovost for ICU doctors. If IV solutions need to be prepared, such as creating a dilution of KCl for a patient, this task may also be beyond a nurse aide's certification.
