Which of the following is a rationale for prescribing total parenteral nutrition (TPN) for a patient with inflammatory bowel disease (IBD)?
To provide essential nutrients while allowing the bowel to rest and heal.
To reduce inflammation and control symptoms of IBD.
To stimulate the bowel and promote regular bowel movements.
To prevent malnutrition and promote weight gain.
The Correct Answer is A
Choice A rationale
Total parenteral nutrition (TPN) provides essential nutrients intravenously, allowing the bowel to rest and heal, which is important in the management of inflammatory bowel disease (IBD).
Choice B rationale
While reducing inflammation and controlling symptoms are important goals in IBD management, TPN is primarily used to provide nutrition and allow the bowel to rest.
Choice C rationale
Stimulating the bowel is not the purpose of TPN. TPN is used to give the digestive tract a break while ensuring the patient receives necessary nutrients.
Choice D rationale
Preventing malnutrition and promoting weight gain are secondary benefits of TPN, but the primary rationale is to provide nutrients while allowing the bowel to rest and heal.
