Final answer:
An RN must confirm that the LPN has received special training in administering I.V. therapy; this task requires additional qualifications beyond the standard LPN scope of practice.
Step-by-step explanation:
The task from the following list for which an RN must confirm that the LPN has received special training is administering I.V. therapy. Tasks such as collecting a urine specimen, assisting the patient with a bath, and ambulating the patient are within the standard scope of practice for an LPN and do not typically require special training. However, administering I.V. therapy involves a higher level of skill and knowledge, and not all LPNs have the authorization to perform this procedure without having completed additional training and certification. It is imperative that the RN verifies the LPN's qualifications for I.V. therapy to ensure patient safety and adhere to healthcare regulations. The LPN's role is to focus on providing treatment under the direct supervision of a registered nurse, which may include reviewing patient history, monitoring the process, and ensuring accurate and sterile procedures are followed.
