NTP Dietary Assessment & Counseling 2 — Questions and Answers
Question 1: Which dietary assessment tool is best suited for capturing habitual food intake over a long period rather than a single day?
- 24-hour dietary recall
- Food frequency questionnaire (FFQ) (Correct answer)
- Weighed food record
- Diet history interview
Correct answer: Food frequency questionnaire (FFQ)
The food frequency questionnaire (FFQ) captures habitual intake patterns over weeks or months, making it ideal for assessing long-term dietary habits.
Question 2: A client reports consuming large amounts of cruciferous vegetables daily. Which nutrient interaction is most important to explore in counseling?
- Calcium absorption interference
- Goitrogen effects on thyroid function (Correct answer)
- Oxalate binding of magnesium
- Phytate inhibition of zinc
Correct answer: Goitrogen effects on thyroid function
Cruciferous vegetables contain goitrogens that can inhibit thyroid hormone synthesis, especially relevant for clients with thyroid conditions.
Question 3: When using motivational interviewing in nutrition counseling, the practitioner should primarily:
- Tell the client what dietary changes to make immediately
- Explore and resolve the client's ambivalence about change (Correct answer)
- Prescribe a strict meal plan and monitor compliance
- Educate the client about macronutrient ratios
Correct answer: Explore and resolve the client's ambivalence about change
Motivational interviewing is a client-centered approach focused on exploring and resolving ambivalence to facilitate intrinsic motivation for change.
Question 4: Which biomarker is most useful for assessing long-term glycemic control in a dietary counseling session for a pre-diabetic client?
- Fasting blood glucose
- Postprandial glucose
- Hemoglobin A1c (HbA1c) (Correct answer)
- Fasting insulin
Correct answer: Hemoglobin A1c (HbA1c)
HbA1c reflects average blood glucose over the prior 2–3 months, providing a reliable indicator of long-term glycemic control.
Question 5: A nutrition practitioner notices a client's diet is high in omega-6 fatty acids and low in omega-3s. The primary concern with this imbalance is:
- Impaired fat-soluble vitamin absorption
- Pro-inflammatory eicosanoid production (Correct answer)
- Reduced bile acid synthesis
- Increased LDL particle size
Correct answer: Pro-inflammatory eicosanoid production
An excess of omega-6 relative to omega-3 fatty acids shifts eicosanoid production toward pro-inflammatory mediators such as prostaglandin E2.
Question 6: Which anthropometric measurement is considered most predictive of cardiometabolic risk beyond BMI?
- Hip circumference
- Mid-upper arm circumference
- Waist circumference (Correct answer)
- Skinfold thickness at the tricep
Correct answer: Waist circumference
Waist circumference is a stronger predictor of cardiometabolic risk than BMI because it reflects visceral adiposity, which drives insulin resistance and inflammation.
Question 7: During a dietary recall, a client underreports food intake. Which population group is most likely to exhibit this pattern?
- Underweight adolescents
- Older adults with cognitive decline
- Overweight and obese individuals (Correct answer)
- Athletes in heavy training
Correct answer: Overweight and obese individuals
Research consistently shows that overweight and obese individuals tend to underreport dietary intake, particularly energy-dense and socially undesirable foods.
