Question

Quizplus · Accepted Answer

Serum albumin is considered the best indicator for a patient in need of Total Parenteral Nutrition (TPN) as it reflects long-term protein status and indicates protein depletion. A low serum albumin level is often indicative of malnutrition and therefore a clear indication for TPN therapy. Hemoglobin and hematocrit indicate anemia and bleeding and are not specific to malnutrition. Creatinine is a test that measures the kidney's ability to filter waste products, but it does not reflect the nutritional status of the patient.
