What type of nutrients are found in a TPN?

Total Parenteral Nutrition (TPN) is a method of delivering nutrients directly into the bloodstream, bypassing the digestive system. This is especially useful for patients who cannot receive nutrition through traditional means due to various medical conditions.

The correct answer indicates that TPN contains vitamins, minerals, and lipids, which are critical for comprehensive nutrient delivery. TPN formulations are designed to provide all essential nutrients to meet the patient's needs, including macronutrients like carbohydrates, fats (in the form of lipids), and proteins (amino acids), as well as micronutrients such as vitamins and minerals.

While the other options mention specific types of nutrients, they do not encompass the full range of what is included in TPN. It is important for patients on TPN to receive these various nutrients to support their overall health and recovery.
