11. Prentice Hall c2002Chapter 1611 Blood Urea Nitrogen (BUN) Blood urea nitrogen (BUN) measures the amount of urea nitrogen, a waste product of protein metabolism, in the blood. BUN is commonly monitored in hospitals and nursing homes. Adult BUN: 7-20 mg/100 ml; men may be slightly higher Predict whether BUN will increase or decrease in the following cases. Dehydrated patient? Overhydration? Elderly patient? Newborn? High protein diet? Malnutrition? Intestinal bleeding? Pregnancy? Kidney failure? Liver failure? Impaired nutrient absorption?
