What should the licensed practical nurse (LPN) do when asked to care for a patient with a central venous catheter for total parenteral nutrition?

The most appropriate response in this scenario is to acknowledge the limitations of the licensed practical nurse's (LPN) scope of practice concerning the care of patients with central venous catheters for total parenteral nutrition. The LPN's role typically involves providing basic patient care, administering medications, and monitoring patients under the supervision of registered nurses (RNs) or other healthcare providers.

Caring for a patient with a central venous catheter, particularly in relation to total parenteral nutrition (TPN), often involves complex procedures that require a higher level of nursing education and training which is usually designated for RNs. This can include tasks such as managing the administration of TPN, monitoring for complications associated with central lines, and performing specific assessments that are critical for patient safety.

In this case, recognizing the need to adhere to the defined scope of practice is essential for patient safety and aligns with professional standards. Emphasizing the importance of working within one's competency boundaries assures that patient care is delivered effectively and safely.
