Question 1: A DTR is working with a patient who has end-stage renal disease (ESRD) on hemodialysis. Which nutrient restriction is typically required?
- Vitamin C only
- Potassium, phosphorus, and sodium (Correct answer)
- Calcium and magnesium
- Iron and zinc
Correct answer: Potassium, phosphorus, and sodium
Patients on hemodialysis typically require restriction of potassium, phosphorus, sodium, and fluid due to impaired renal excretion.
Question 2: The Estimated Average Requirement (EAR) is defined as the nutrient intake level that meets the needs of what percentage of healthy individuals?
- 25%
- 50% (Correct answer)
- 75%
- 97.5%
Correct answer: 50%
The EAR is the intake level that meets the estimated nutrient requirements of 50% of healthy individuals in a group.
Question 3: A DTR counseling a patient with celiac disease should advise avoidance of which grains?
- Rice, corn, and millet
- Wheat, barley, and rye (Correct answer)
- Quinoa, amaranth, and buckwheat
- Oats (certified GF), rice, and sorghum
Correct answer: Wheat, barley, and rye
Celiac disease requires strict avoidance of wheat, barley, and rye, as these contain gluten that triggers an autoimmune intestinal response.
Question 4: In a HACCP plan, a Critical Control Point (CCP) is best described as:
- Any step where a food safety hazard may occur
- A step where control can be applied to prevent or eliminate a food safety hazard (Correct answer)
- The final inspection point before food is served
- A documented record of food temperatures
Correct answer: A step where control can be applied to prevent or eliminate a food safety hazard
A CCP is a step in the food production process where control measures can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level.
Question 5: A DTR is calculating the food cost percentage for a school lunch program. If the food cost is $1.20 and the meal is reimbursed at $3.00, what is the food cost percentage?
- 25%
- 30%
- 40% (Correct answer)
- 45%
Correct answer: 40%
$1.20 ÷ $3.00 × 100 = 40% food cost percentage.
Question 6: Which condition is characterized by inflammation of the pancreas that may require a low-fat diet and potentially enteral nutrition support?
- Crohn's disease

- 0 additional kcal
- +100 kcal/day
- +340 kcal/day
- +452 kcal/day (Correct answer)
Correct answer: +452 kcal/day
The DRI recommends an additional 452 kcal/day in the third trimester compared to pre-pregnancy needs, up from 340 kcal/day in the second trimester.
