In the Academy/ADA exchange system, one carbohydrate serving equals 15 grams of carbohydrate.
Question 2: Which vitamin deficiency is most commonly associated with night blindness in malnourished children?
- Vitamin A (Correct answer)
- Vitamin D

Question 3: A DTR is updating a food service production record. Which information is NOT typically included?
- Wholesale cost of ingredients per supplier invoice (Correct answer)
- Planned and actual quantities prepared
- Serving size and number of portions
- Temperature logs for hot-hold equipment
Correct answer: Wholesale cost of ingredients per supplier invoice
Production records capture quantities, temperatures, and serving data, but supplier invoice costs are tracked in purchasing records, not production records.
Question 4: A DTR observes a food service employee placing raw chicken directly above ready-to-eat vegetables in the walk-in cooler. This violates which food safety principle?
- Proper raw food storage hierarchy (Correct answer)
- Temperature danger zone control
- First-in, first-out (FIFO) rotation

Raw poultry must be stored below ready-to-eat foods to prevent drip contamination per food storage hierarchy rules.
Question 5: An RDN asks the DTR to calculate the nitrogen balance for a hospitalized patient who consumes 80 g of protein daily and has a 24-hour urine urea nitrogen (UUN) of 10 g. Using the standard formula, what is the nitrogen balance?
- +2.9 g (Correct answer)
- -2.9 g
- +4.0 g
- -4.0 g
Correct answer: +2.9 g
Using N balance = protein intake ÷ 6.25 − (UUN + 4): 80 ÷ 6.25 = 12.8; 12.8 − (10 + 4) = −1.2 g, indicating catabolism.
