An RN is making assignments for client care to an LPN at the beginning of the shift. Which of the following assignments should the LPN question?

The LPN should question assignment D (replacing the cartridge and tubing on a PCA pump) because this task involves medication administration and intravenous therapy, which are typically outside the LPN's scope of practice. LPNs are not trained to handle complex medication delivery systems like PCA pumps, as this requires specialized knowledge and skills that are within the RN's scope of practice. It is crucial for patient safety that tasks are assigned to healthcare providers based on their education, training, and scope of practice to prevent errors and ensure quality care. Assignments A, B, and C are within the LPN's scope of practice and can be safely performed without questioning.
