A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify that which of the following supplements is contraindicated for concurrent use with warfarin?

Answer: C. Keep the solution refrigerated until 1 hr before infusion.

Rationale:

A. Change the solution every 36 hr:
Total parenteral nutrition (TPN) solutions should be changed every 24 hours to prevent contamination and bacterial growth. Therefore, changing the solution every 36 hours would not adhere to best practice guidelines.

B. Obtain the client's weight three times a week:
While monitoring the client’s weight is important, especially for those on TPN, it should be done daily to accurately assess fluid balance and nutritional status. This frequency allows for timely adjustments to the TPN regimen.

C. Keep the solution refrigerated until 1 hr before infusion:
This action is correct. TPN solutions must be refrigerated to maintain stability and prevent bacterial growth. Allowing the solution to come to room temperature for at least 1 hour before infusion helps ensure that the solution is at a safe and comfortable temperature for the client.

D. Check the client's WBC count daily:
While monitoring the WBC count can be important for detecting infection, it is not a standard daily requirement specifically related to TPN administration. The priority is to focus on monitoring the client's nutritional status and fluid balance more closely during TPN therapy

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.
