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?

Ask the healthcare provider to re-schedule the scan

Send a suction catheter with the client in case of aspiration during the scan

Shut the feeding off 30-60 minutes before the scan

Connect the feeding tube to continuous suction before and during the exam

Answer and Explanation

The Correct Answer is C

Choice A reason:Rescheduling the scan is not necessary unless there are other contraindications or scheduling conflicts.

Choice B reason:Sending a suction catheter is a precautionary measure, but it does not address the management of the feeding tube during the scan.

Choice C reason:Shutting off the feeding 30-60 minutes before the scan is a standard practice to reduce the risk of aspiration and to ensure that the stomach contents do not interfere with the imaging.

Choice D reason:Connecting the feeding tube to continuous suction is not typically required unless there is a specific concern for aspiration or gastric content management during the scan.

Correct Answer is A

Explanation

Choice A: Hyperglycemia The reason hyperglycemia is a risk when the prescribed dwell time is not maintained is due to the glucose present in the dialysate. The dialysate used in PD often contains glucose, which acts as an osmotic agent to facilitate fluid removal from the blood. If the dwell time is too short, there may not be enough time for the glucose to be absorbed, leading to higher levels of glucose in the blood. Conversely, if the dwell time is too long, excessive glucose absorption can occur, also leading to hyperglycemia. For patients with diabetes mellitus, maintaining the prescribed dwell time is essential to manage their blood glucose levels effectively. The normal range for fasting blood glucose is typically between 70 to 99 mg/dL, and for diabetes patients, maintaining blood glucose levels as close to the normal range as possible is crucial to prevent complications.

Choice B: Disequilibrium Syndrome Disequilibrium syndrome is characterized by neurological symptoms resulting from rapid changes in the composition of extracellular fluids during dialysis. This condition is more commonly associated with hemodialysis due to the rapid shifts that can occur with this modality. In PD, the risk of disequilibrium syndrome is significantly lower because the exchange of solutes and fluids is more gradual. Therefore, while important to consider, it is not the primary complication associated with the maintenance of dwell time in PD.

Choice C: Peritonitis Peritonitis, an infection of the peritoneal cavity, is a serious complication of PD but is not directly related to the duration of dwell time. It is typically caused by contamination during the exchange process or catheter-related infections. While proper technique and hygiene are critical in preventing peritonitis, the dwell time itself does not influence the risk of developing this infection.

Choice D: Hyperphosphatemia Hyperphosphatemia refers to elevated levels of phosphate in the blood and is a concern in patients with renal failure due to the kidneys’ inability to excrete phosphate effectively. The dwell time in PD may affect the removal of phosphate to some extent; however, it is not the primary concern related to the maintenance of dwell time. Phosphate binders and dietary restrictions are commonly used to manage phosphate levels in PD patients.

A. Metabolic alkalosis B. Respiratory alkalosis C. Metabolic acidosis D. Respiratory acidosis

Correct Answer is C

Explanation

Choice A reason: Metabolic alkalosis would present with an elevated pH and HCO3, which is not the case here.

Choice B reason: Respiratory alkalosis would present with an elevated pH and a decreased PaCO2, which is not the case here.

Choice C reason: Metabolic acidosis is indicated by a decreased pH and HCO3, which aligns with the ABG findings provided.

Choice D reason: Respiratory acidosis would present with a decreased pH and an elevated PaCO2, which is not the case here.
