Clinical Nutritionist Practice Test 2026 - Free Practice Questions and Study Guide

Total Parenteral Nutrition (TPN) is indicated for pediatric patients primarily when bowel rest is required for an extended duration, typically exceeding five days. This situation arises in clinical scenarios where the gastrointestinal tract must be allowed to heal or recover, such as after certain surgeries or in cases of severe gastrointestinal disorders that inhibit normal digestive function.

In these situations, TPN provides essential nutrients intravenously, circumventing the need for the gastrointestinal tract to function. It ensures that the child receives adequate energy, protein, fats, vitamins, and minerals to maintain their nutritional status while not eating orally.

In contrast, the other situations mentioned would not justify the use of TPN. If a child is recovering from minor surgeries, they may often still be able to consume some nutrients orally or tolerate enteral feeding, making TPN unnecessary. Mild nausea typically does not warrant TPN, as it may not preclude oral intake and can often be managed with dietary adjustments. Lastly, when a child is consuming solid food adequately, it demonstrates that their gastrointestinal tract is functioning appropriately, and they do not need parenteral nutrition support.
