A nurse is caring for a client who has a small-bore jejunostomy tube and is receiving a continuous tube feeding with a high-viscosity formula. Which of the following actions should the nurse take to prevent the tubing from clogging?

Choice A reason: TPN is a form of nutrition that is delivered directly into the bloodstream through a central venous catheter. It is used for clients who have impaired or nonfunctional gastrointestinal tracts, such as those with acute kidney injury, bowel obstruction, or short bowel syndrome.

Choice B reason: The TPN does not necessarily have higher levels of vitamins than the recommended daily intake. The TPN is individually tailored to meet the client's nutritional needs, which may vary depending on their condition, weight, and laboratory values.

Choice C reason: The TPN does not ensure that the client's glucose level stays within the expected range. In fact, TPN can cause hyperglycemia due to the high concentration of dextrose in the solution. The client's blood glucose level should be monitored frequently and insulin should be administered as prescribed to prevent complications.

Choice D reason: The TPN is not higher in fats and protein, but lower in carbohydrates. The TPN contains a balanced mixture of macronutrients, including carbohydrates, proteins, and lipids, as well as micronutrients, such as electrolytes, vitamins, and minerals. The ratio of these components may vary depending on the client's nutritional needs and goals.

Choice A reason: Changing the feeding to a continuous infusion may not improve the constipation, as it does not address the fluid deficit or the fiber content of the formula. Continuous infusion may also increase the risk of aspiration, diarrhea, and bacterial contamination.

Choice B reason: Increasing the amount of free water can help prevent or treat constipation by hydrating the stool and facilitating its passage. The client's fluid intake and output indicate a fluid deficit, which can contribute to constipation. The recommended fluid intake for adults is 30 to 35 mL/kg/day.

Choice C reason: Decreasing the infusion rate of feeding may worsen the constipation, as it reduces the caloric and fluid intake of the client. The infusion rate should be based on the client's nutritional needs and tolerance.

Choice D reason: Requesting a prescription for a diuretic is not appropriate, as it would further dehydrate the client and aggravate the constipation. Diuretics are indicated for clients with fluid overload, not fluid deficit.
