Nitrogen Balance Studies

Nitrogen Balance (NB) = Nitrogen Intake (NI) - Nitrogen Loss (NL)
NB > -5g/day = severe stress
NB = 0 to -5g/day = moderate stress

NI = Protein intake (g/day ÷ 6.25)
NL = Urinary Urea Nitrogen (UUN, in g/day) + 4 g
UUN is derived from a 24-hour urine specimen
Normal range = 6 - 17 grams/24 hours

+ NB = anabolic state with a net gain in body protein
- NB = catabolic state with a net loss in body protein

Q 2 below use the above information on Nitrogen balance to:
a. Calculate the client's recommended protein intake.
b. Calculate the client's NB.
c. Indicate whether the client is in + or - nitrogen balance.
d. Discuss the implications of the findings.

2. 89-year-old male, weight 142 lbs., protein intake of 69 grams and UUN = 6 grams
