A nurse is planning care for a client who has a new prescription for total parenteral nutrition (TPN). Which of the following actions should the nurse plan to take?
Change the IV tubing for TPN solution every 72 hr.
Discard the remaining TPN solution that is still infusing after 24 hr.
Change the dressing around the IV site weekly.
Remove TPN from the refrigerator 5 min before infusing it.
The Correct Answer is B
Choice A rationale:
Changing the IV tubing for TPN solution every 72 hr is not necessary unless there is a complication or a specific reason to do so. TPN tubing should be changed based on the facility's protocol and the patient's condition, not on a fixed time frame.
Choice B rationale:
This choice is the correct answer. TPN solutions are susceptible to bacterial growth due to their nutrient-rich composition. Discarding any remaining TPN solution after 24 hr helps minimize the risk of bacterial contamination and subsequent infection in the patient.
Choice C rationale:
Changing the dressing around the IV site weekly is a common practice for peripheral IV sites, but TPN administration usually requires a more frequent dressing change due to the higher risk of infection associated with central venous access.
Choice D rationale:
Removing TPN from the refrigerator 5 min before infusing it is unnecessary. TPN solutions are typically stored in a refrigerator and should be brought to room temperature gradually before administration. However, 5 minutes is not sufficient time for the solution to reach an appropriate temperature.

Correct Answer is B
Explanation
Choice A rationale:
Serving hot foods at mealtime might worsen the client's nausea, as strong odors and high temperatures can exacerbate feelings of nausea.
Choice B rationale:
Limiting fluid intake between meals can help prevent overfilling the stomach, which can contribute to nausea in clients with equilibrium imbalances. Consuming fluids between meals, rather than with meals, can also aid in better digestion and reduce the likelihood of nausea.
Choice C rationale:
Encouraging the client to eat even if nauseated could potentially worsen their symptoms and lead to an aversion to eating due to the association of food with nausea.
Choice D rationale:
Providing low-fat carbohydrates with meals may be beneficial for some clients, but it doesn't directly address the issue of nausea related to equilibrium imbalance. The focus should be on strategies that prevent nausea rather than specific meal components.
Correct Answer is D
Explanation
Choice A rationale:
Cheddar cheese does not contain a significant amount of potassium. It is a dairy product that is richer in calcium and fat than in potassium.
Choice B rationale:
Raw tomato contains some potassium, but it's not as high as the other options. It's a good source of vitamins and antioxidants, but for hypokalemia, more potassium-rich options are better.
Choice C rationale:
Brown rice contains moderate levels of potassium, but it is not as high as the potassium content in a baked potato.
Choice D rationale:
One small baked potato is a great source of potassium. Potatoes are known for their high potassium content, making them suitable for individuals with hypokalemia, as potassium is essential for proper muscle and nerve function.
