The Prognostic Nutrition Index stands for which term?

• A. Prognostic Nutrition Index
• B. Prognostic Neutron Index
• C. Protein Nutrition Index
• D. Pathway Nutritional Index

Answer: (A)

This question tests recognizing what the acronym PNI stands for. The standard name is Prognostic Nutrition Index, with the acronym built from Prognostic, Nutrition, Index. In clinical use, the Prognostic Nutrition Index is calculated from parameters like serum albumin and total lymphocyte count to help assess nutritional/immune status and prognosis in patients needing nutrition support or undergoing cancer treatment. The other phrase options don’t match the established name (they introduce terms like neutron, protein, or pathway that aren’t used in this index).
