Dextrose Calculation in TPN

A patient is being started on Total Parenteral Nutrition (TPN) due to severe malnutrition and inability to meet nutritional requirements via the gastrointestinal tract. TPN solutions typically contain a mixture of carbohydrates, proteins, lipids, vitamins, and minerals to provide complete nutrition. The physician prescribes a TPN solution that delivers ______ grams of dextrose per liter of solution.

During the initial assessment, the nurse notes that the TPN order specifies the patient should receive 50% Dextrose. Considering that Dextrose contributes significantly to the caloric intake of patients on TPN, it is important to accurately calculate the dextrose delivery.
