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.

Answer and Explanation

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.

Correct Answer is B

Explanation

Choice A rationale

Hypokalemia involves low potassium levels and is not treated with sodium polystyrene sulfonate. This drug is used to treat elevated potassium levels.

Choice B rationale

Hyperkalemia indicates high potassium levels in the blood. Sodium polystyrene sulfonate (Kayexalate) works by exchanging sodium ions for potassium ions in the intestines, thereby lowering blood potassium levels.

Choice C rationale

Hyponatremia, or low sodium levels, is not treated with sodium polystyrene sulfonate, which targets potassium removal.

Choice D rationale

Hypocalcemia refers to low calcium levels and is unrelated to the action of sodium polystyrene sulfonate, which addresses potassium imbalance.

A. Intestinal malabsorption syndrome. B. Intestinal parasites. C. Chronic blood loss. D. Dietary iron restrictions.

Correct Answer is C

Explanation

Choice A rationale

Intestinal malabsorption syndrome is not typically associated with ulcerative colitis or anemia caused by this condition. Malabsorption is more often related to other gastrointestinal conditions.

Choice B rationale

Intestinal parasites are not a common cause of anemia in individuals with ulcerative colitis. The chronic inflammation and blood loss are more likely contributors.

Choice C rationale

Chronic blood loss from the intestinal lining due to ulcerative colitis is a major contributing factor to anemia. The ongoing inflammation and ulceration can cause significant blood loss over time.

Choice D rationale

Dietary iron restrictions are not typically associated with ulcerative colitis. Anemia in this context is more likely due to chronic blood loss rather than dietary deficiencies.
