Sample itemWhat does a positive nitrogen balance usually indicate?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Protein synthesis exceeds breakdown
Positive nitrogen balance occurs in growth, pregnancy, and recovery when protein synthesis and retention exceed protein catabolism and nitrogen loss.
Option by option
A. No amino acids are absorbed
Absorption may occur in both states.
B. Urea production has stopped
Urea production does not stop.
C. Protein breakdown exceeds synthesis
Negative balance reflects greater breakdown.
D. Protein synthesis exceeds breakdown (correct)
Correct: net protein accretion produces positive balance.
