The nurse notes that the primary health-care provider has prescribed that the total parenteral nutrition (TPN) a client has been receiving for the past 10 days be discontinued and changed to 0.9% normal saline. Which action would be most appropriate for the nurse to take?

A) Stop the TPN and change the solution to 0.9% normal saline as soon as it is available.
B) Allow the remaining TPN to infuse until the bag is empty and then change the solution to 0.9% normal saline.
C) Gradually reduce the rate of the TPN over the next 4 to 6 hours and then change the solution to 0.9% normal saline.
