A nurse is assisting in the selection of food for a client who has hypokalemia. Which of the following foods should the nurse select that contains the greatest amount of potassium?

The nurse should plan to change the IV tubing for the TPN solution every 72 hours. This is necessary to maintain the sterility of the system and minimize the risk of infection. TPN solutions are prone to bacterial growth, and changing the tubing regularly helps prevent contamination.

Removing TPN from the refrigerator 5 minutes before infusing it is not necessary. TPN solutions are typically stored in the refrigerator to maintain their stability and prevent spoilage. It should be brought to room temperature over a longer period of time, usually 30-60 minutes, before administration.

Discarding the remaining TPN solution that is still infusing after 24 hours is unnecessary. TPN solutions can typically be infused for up to 24 hours without compromising their safety and efficacy. However, it is important to monitor the solution closely for any signs of contamination or degradation, and if any concerns arise, the nurse should consult with the healthcare provider.

Changing the dressing around the IV site weekly is not specific to TPN administration. Dressing changes for peripheral IV sites are typically performed according to facility protocols and the condition of the site, but they are not necessarily done on a weekly basis. The frequency of dressing changes depends on factors such as the type of dressing used, the patient's condition, and any signs of infection or dislodgement.

"I should limit the amount of fiber in my diet": This statement demonstrates an understanding of the teaching. In Crohn's disease, certain types of fiber can be difficult to digest and may worsen symptoms such as abdominal pain, diarrhea, and bowel obstruction. Therefore, it is often recommended to limit the intake of high-fiber foods during active disease flares.

"I will need to take mild laxatives to help me have a bowel movement": Taking laxatives is not typically recommended for individuals with Crohn's disease unless specifically prescribed by a healthcare provider. Laxatives can further irritate the intestines and potentially worsen symptoms. Therefore, this statement does not demonstrate an understanding of the teaching.

"I am likely to gain weight due to this disease": Weight loss is a more common occurrence in individuals with Crohn's disease due to factors such as decreased appetite, malabsorption, and increased metabolism. Weight gain is not typically associated with the disease, so this statement does not indicate an understanding of the teaching.

"Avoiding glutamine will help me recover from this disease": Glutamine is an amino acid that plays a role in gut health and repair. It is often considered beneficial for individuals with Crohn's disease as it supports intestinal healing. Therefore, avoiding glutamine would not be recommended for recovery from the disease. This statement does not indicate an understanding of the teaching.
