A nurse is preparing to administer total parenteral nutrition to a client. Which of the following actions should the nurse take?

A. Keep the solution refrigerated until 1 hr before infusion. This action is correct because total parenteral nutrition (TPN) solutions should be kept refrigerated to maintain their stability and prevent bacterial growth. The solution should be removed from the refrigerator about one hour before infusion to allow it to reach room temperature, which helps to reduce the risk of discomfort and complications during administration. B. Check the client’s WBC count daily. This action is not typically required specifically for TPN administration. While monitoring the client’s overall health is important, daily WBC counts are not a standard part of TPN management unless there is a specific concern for infection. C. Change the solution every 36 hr. This action is incorrect because TPN solutions are usually changed every 24 hours to reduce the risk of infection and ensure the client receives the correct nutrient composition. D. Obtain the client’s weight three times a week. This action is not directly related to the immediate administration of TPN. While monitoring the client’s weight is important to assess nutritional status and fluid balance, it is not a step in the preparation or administration of TPN.
