Answer: A
Sepsis, fever, infection and trauma accelerate the loss of nitrogen.
These are catabolic stresses. Stress hormones break down muscle protein to supply amino acids for glucose production and for the immune response, and the nitrogen from the amino acids is excreted as urea. The patient goes into negative nitrogen balance, which is why protein needs rise sharply after injury, burns and severe infection.
Zinc, calcium and iron can also be affected by illness, but the characteristic, measurable loss in these states is the nitrogen of body protein.
