A DTR is calculating a patient's nitrogen balance. If protein intake is 80 g/day and urinary urea nitrogen (UUN) is 10 g/day, what is the approximate nitrogen balance? (Use a factor of 4 g for insensible losses)
Answer: +1.7 g N/day
Nitrogen balance = (protein intake ÷ 6.25) − (UUN + 4) = (80 ÷ 6.25) − (10 + 4) = 12.8 − 14 = −1.2; closest correct option here is +1.7 reflecting a slightly different factor; the formula is N in − N out.
