What are the appropriate laboratory values to monitor during parenteral nutrition?

Monitoring laboratory values during parenteral nutrition is crucial for ensuring patient safety and the effectiveness of nutritional support. The correct choice encompasses a comprehensive range of essential laboratory values that reflect a patient's metabolic state and nutritional status.

The Basic Metabolic Panel (BMP) and Comprehensive Metabolic Panel (CMP) provide information on electrolytes, glucose, and kidney function, which are vital since parenteral nutrition can lead to imbalances. Monitoring magnesium and phosphorus levels is particularly important, as deficiencies or excesses can lead to significant complications. Additionally, triglycerides (denoted as Trg) are monitored to assess lipid metabolism, particularly since parenteral nutrition often includes lipid emulsions.

Together, these values enable healthcare providers to make informed adjustments to the nutrient composition of parenteral solutions, ensuring that the patient receives appropriate caloric intake and prevents or manages potential complications such as refeeding syndrome, electrolyte imbalances, and hepatic dysfunction. This makes the choice the most appropriate for ongoing assessment during parenteral nutrition.
