A client is receiving continuous enteral nutrition through a nasogastric small-bore silicone feeding tube. What should the nurse plan for when this client has a computed tomography (CT) scan ordered?

Choice A reason: A fractured femur, while a serious injury, does not inherently contraindicate the use of lipid emulsions. These patients may require additional nutrition if they are unable to eat adequately by mouth, and lipid emulsions can be part of their parenteral nutrition regimen if needed.

Choice B reason: Severe anorexia nervosa is a condition that can lead to malnutrition and may necessitate the use of parenteral nutrition, including lipid emulsions, to provide essential nutrients. However, care must be taken to avoid refeeding syndrome, a potentially fatal condition that can occur when malnourished patients begin to refeed too quickly.

Choice C reason: Gastrointestinal obstruction is a condition that could be exacerbated by the administration of lipid emulsions. In cases of obstruction, enteral or parenteral nutrition may need to be carefully managed or avoided until the obstruction is resolved to prevent further complications. While lipid emulsions are a valuable component of parenteral nutrition, their use must be carefully considered in the context of the patient’s overall clinical condition. In the case of gastrointestinal obstruction, the nurse would be most concerned about the prescription of a lipid emulsion due to the potential for exacerbating the obstruction and complicating the patient’s condition.

Choice D reason: Chronic diarrhea and vomiting can lead to dehydration and electrolyte imbalances, but they do not directly contraindicate the use of lipid emulsions. However, the underlying cause of these symptoms should be addressed, and fluid and electrolyte balance should be carefully monitored.

Choice A: RBC count The red blood cell (RBC) count is not typically decreased by hemodialysis. Hemodialysis does not remove cells from the blood. However, patients with chronic kidney disease often have anemia, which is a low RBC count, due to a decrease in the production of erythropoietin by the kidneys. Erythropoietin is a hormone that stimulates the bone marrow to produce RBCs. Anemia in these patients is treated with erythropoiesis-stimulating agents, not dialysis.

Choice B: Protein Protein levels are not directly affected by hemodialysis. However, patients on hemodialysis may have lower protein levels due to dietary restrictions or protein loss during the treatment. It is important for patients to manage their protein intake to prevent malnutrition and maintain overall health.

Choice C: Potassium Potassium levels are expected to decrease following hemodialysis. Potassium is an electrolyte that is normally filtered out by the kidneys. In patients with kidney failure, potassium levels can build up in the blood and cause serious heart problems. Hemodialysis removes excess potassium from the blood, which helps to prevent complications such as cardiac arrhythmia. The normal range for serum potassium is 3.5 to 5.0 mmol/L. After a hemodialysis treatment, a nurse should expect to find a decrease in potassium levels in the laboratory data of a client. This is because hemodialysis effectively removes excess potassium, which can accumulate in the blood due to reduced kidney function. Maintaining proper potassium levels is crucial for preventing heart complications in patients with kidney failure.

Choice D: Calcium Calcium levels are not typically decreased by hemodialysis. In fact, calcium levels can be affected by the dialysate used during hemodialysis. Some dialysates contain calcium, and this can actually increase the patient’s blood calcium levels. Patients with kidney failure may also have secondary hyperparathyroidism, which affects calcium levels, and they may be treated with calcium supplements or vitamin D analogs to manage their calcium levels.
