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?

Lactated Ringer's

Dextrose 10% in water

0.45% sodi’m chloride

0.9% sodium chloride

Answer and Explanation

The Correct Answer is B

A) Lactated Ringer's: Lactated Ringer's solution is not app’opriate in this si’uation because it does not provide the necessary nutrients found in TPN. It is primarily used for fluid replacement and maintenance and does not contain the essential macronutrients required for TPN.

B) Dextrose 10% in water: This is the correct fluid to administer when the current bag of TPN has finished infusing and the next bag is not yet available. Dextrose 10% in water provides a source of glucose, which can help prevent hypoglycemia in clients dependent on TPN. While it does not provide the full spectrum of nutrients found in TPN, it can temporarily meet the client's caloric needs until the next bag of TP’ becomes available.

C) 0.45% sodium chloride: This solution, also known as half-normal saline, is hypotonic and primarily used for hydration and maintenance fluids. It does not provide adequate nutrition and is not a suitable substitute for TPN.

D) 0.9% sodium chloride: This solution, also known as normal saline, is isotonic and used for fluid resuscitation, maintenance, and replacement. Like 0.45% sodium chloride, it does not contain the necessary nutrients for TPN and is not appropriate as a substitute.

Correct Answer is D

Explanation

D) Calcium: Calcium supplements can interfere with the absorption of levothyroxine when taken concurrently. Levothyroxine absorption can be significantly reduced if taken with calcium-containing supplements or foods high in calcium. Therefore, clients should wait at least 4 hours after taking levothyroxine before consuming calcium supplements to ensure optimal absorption of the thyroid medication.

A) Zinc: Zinc supplements do not significantly interfere with the absorption of levothyroxine. While zinc can bind to levothyroxine and potentially decrease its absorption, the effect is minimal compared to calcium. However, it is generally recommended to take zinc supplements at least 4 hours apart from levothyroxine to avoid any potential interaction.

B) Vitamin C: Vitamin C supplements do not interfere with the absorption of levothyroxine and can be taken concurrently without significant interactions. There is no need for clients to wait a specific amount of time between taking levothyroxine and vitamin C supplements.

C) Ginkgo biloba: Ginkgo biloba supplements have not been shown to have a significant impact on the absorption of levothyroxine. However, given the variability in individual responses to supplements, it is still prudent to separate the administration of levothyroxine and ginkgo biloba by at least 4 hours to minimize any potential interactions.

A. "The TPN will stimulate your appetite so that you'll be able to eat more food." B. "The TPN contains medication that will help your digestive tract absorb nutrients." C. "The TPN will provide nutrients while your bowels have time to rest." D. "The TPN will help keep your bowels clear in case you need surgery."

Correct Answer is C

Explanation

C) "The TPN will provide nutrients while your bowels have time to rest": Total parenteral nutrition (TPN) is a method of providing nutrition intravenously to clients who are unable to tolerate or absorb adequate nutrients through the gastrointestinal tract. It bypasses the digestive tract entirely, delivering a balanced mixture of nutrients directly into the bloodstream. One of the primary indications for TPN is to provide nutritional support while allowing the gastrointestinal tract to rest, particularly in cases where the bowels are inflamed, injured, or unable to function properly. By bypassing the digestive system, TPN can provide essential nutrients to the body while reducing the workload on the gastrointestinal tract. Therefore, the nurse should include this information in the teaching to help the client understand the purpose and benefits of TPN therapy.

A) "The TPN will stimulate your appetite so that you'll be able to eat more food": TPN does not stimulate appetite. In fact, TPN is often used when the client cannot eat or tolerate oral intake due to various medical conditions or gastrointestinal issues. Therefore, this statement is incorrect and may confuse the client about the purpose of TPN therapy.

B) "The TPN contains medication that will help your digestive tract absorb nutrients": TPN does not contain medication to help the digestive tract absorb nutrients. Instead, TPN provides nutrients directly into the bloodstream, bypassing the need for digestion. This statement is inaccurate and does not accurately describe the mechanism of action of TPN.

D) "The TPN will help keep your bowels clear in case you need surgery": While TPN can help maintain nutritional status in clients who are unable to eat or tolerate oral intake, it is not primarily used to keep the bowels clear for surgery. Bowel preparation for surgery typically involves other interventions such as bowel rest, mechanical cleansing, or medication administration. Therefore, this statement is not directly related to the purpose of TPN therapy and may mislead the client about its intended use.
