A nurse is caring for a client whose current bag of total parenteral nutrition (TPN) has finished infusing, and the next bag is not yet available. Which of the following fluids should the nurse prepare to administer?

A) Insomnia: While insomnia can be a side effect of some medications, it is not commonly associated with carbamazepine. Therefore, it is not a priority adverse effect for the client to monitor.

B) Blurred vision: This is the correct answer. Blurred vision is a common adverse effect of carbamazepine. It can occur due to the medication's effects on the central nervous system ’nd may indicate the need for dose adjustment or further evaluation by the healthcare provider. Clients should be instructed to report any changes in vision promptly.

C) Tachypnea: Tachypnea, or rapid breathing, is not typically associated with carbamazepine use. While respiratory depression is a concern with some medications, it is not a common adverse effect of carbamazepine.

D) Metallic taste: Metallic taste is a less common adverse effect of carbamazepine. While it may occur, it is not as prevalent or significant as blurred vision, which can impact the client's daily activities and safety.

A) Discontinue the infusion: While discontinuing the parenteral nutrition infusion may be necessary in severe cases of hypoglycemia, it should not be the initial action unless the client's condition warrants it. Discontinuing the infusion without providing alternative sources of glucose may exacerbate the hypoglycemia and lead to further complications.

B) Obtain arterial blood gases: Arterial blood gases (ABGs) are not typically indicated for evaluating hypoglycemia. While ABGs provide valuable information about acid-base balance and oxygenation status, they do not directly assess blood glucose levels or contribute to the management of hypoglycemia.

C) Warm formula to room temperature: Warming the parenteral nutrition formula to room temperature may improve comfort during administration, but it is not directly related to managing hypoglycemia. Hypoglycemia requires prompt intervention to raise blood sugar levels, and warming the formula would not address the immediate need for glucose supplementation.

D) Administer IV dextrose: Hypoglycemia is a potentially serious complication of parenteral nutrition administration, especially if the infusion rate is too high or if the client's metabolic needs are not adequately met. IV dextrose, a concentrated glucose solution, is the most appropriate intervention for treating hypoglycemia in this situation. It provides a rapid source of glucose to raise blood sugar levels quickly and effectively.
