The nurse is caring for a group of clients with the help of a practical nurse (PN). Which nursing action(s) should the nurse assign to the PN? (Select all that apply.)

A. Obtain postoperative vital signs: This task is within the scope of practice for a practical nurse (PN) as it involves monitoring and recording the vital signs of a client post-surgery, which is a fundamental nursing skill. B. Start the second blood transfusion: This task is typically reserved for a registered nurse (RN) due to the complexity and potential complications associated with blood transfusions. C. Initiate PCA pumps: The initiation of PCA pumps is generally a responsibility of the RN because it requires assessment and understanding of the medication dosage and patient pain management needs. D. Perform daily surgical dressing change: This is an appropriate task for a PN as it involves wound care and monitoring for signs of infection, which are within the PN's capabilities. E. Administer a dose of insulin per sliding scale: Administering medications, including insulin, is a task that can be delegated to a PN, provided they have the knowledge and skills to do so safely.
