SECTION 1: FOUNDATIONS OF NUTRITION (Questions 1-15)
Q1: According to the Dietary Guidelines for Americans, which of the following is a key
recommendation for healthy eating patterns?
• A. Consume less than 10% of calories per day from added sugars. [CORRECT]
• B. Eliminate all carbohydrates from the diet
• C. Consume at least 50% of calories from saturated fats
• D. Avoid all dietary fiber
Correct Answer: A
Rationale: The Dietary Guidelines for Americans recommend consuming less than 10% of
calories per day from added sugars (A). Carbohydrates are essential macronutrients and should
not be eliminated (B). Saturated fats should be limited to less than 10% of calories, not increased
(C). Dietary fiber is crucial for digestive health and should be consumed regularly (D).
Q2: Which component of the ABCD nutrition assessment involves measuring height, weight,
BMI, and waist circumference?
• A. Biochemical assessment
• B. Anthropometric assessment [CORRECT]
• C. Clinical assessment
• D. Dietary assessment
Correct Answer: B
Rationale: Anthropometric assessment (B) involves physical measurements of the body
including height, weight, BMI, and waist circumference. Biochemical assessment (A) involves
laboratory tests, clinical assessment (C) involves physical examination for signs of deficiency,
and dietary assessment (D) involves evaluating food intake patterns.
,Q3: The MyPlate food guidance system recommends that approximately what proportion of your
plate should consist of fruits and vegetables combined?
• A. One-quarter
• B. One-third
• C. One-half [CORRECT]
• D. Two-thirds
Correct Answer: C
Rationale: MyPlate recommends that fruits and vegetables together should fill half of your plate
(C), with vegetables comprising slightly more than fruits. Grains and protein foods each occupy
about one-quarter of the plate, and dairy is represented as a side serving.
Q4: Which of the following factors influencing food choices is considered an environmental
factor?
• A. Religious beliefs about food
• B. Food availability and access in the community [CORRECT]
• C. Personal taste preferences
• D. Emotional stress eating
Correct Answer: B
Rationale: Environmental factors include food availability, access, and the surrounding food
environment (B). Religious beliefs (A) are cultural factors, taste preferences (C) are personal
factors, and emotional eating (D) is a psychological factor influencing food choices.
Q5: A nutritionist is conducting a 24-hour dietary recall with a client. What is the primary
limitation of this assessment method?
• A. It requires expensive laboratory equipment
• B. It may not represent typical eating patterns [CORRECT]
• C. It cannot identify specific nutrient deficiencies
• D. It takes several weeks to complete
,Correct Answer: B
Rationale: The 24-hour recall (B) captures only one day's intake, which may not reflect typical
eating patterns due to day-to-day variation. It does not require lab equipment (A), can identify
potential nutrient inadequacies (C), and is completed in one interview session (D).
Q6: According to the Dietary Guidelines for Americans, which of the following statements about
healthy eating patterns is correct?
• A. Healthy eating patterns should focus on nutrient-dense foods across the lifespan
[CORRECT]
• B. Healthy eating patterns should eliminate all fats from the diet
• C. Healthy eating patterns require identical meals every day
• D. Healthy eating patterns are only necessary during adulthood
Correct Answer: A
Rationale: The Dietary Guidelines emphasize following a healthy eating pattern across the
lifespan that focuses on variety, nutrient density, and amount (A). Healthy fats are essential (B),
variety is encouraged rather than identical meals (C), and healthy eating is important at all life
stages (D).
Q7: Which method of dietary assessment involves having a client record all foods and beverages
consumed over a specified period, typically 3-7 days?
• A. Food frequency questionnaire
• B. 24-hour dietary recall
• C. Food diary or food record [CORRECT]
• D. Direct observation
Correct Answer: C
Rationale: A food diary or food record (C) requires the client to prospectively record intake over
several days. Food frequency questionnaires (A) assess usual intake frequency, 24-hour recalls
(B) are retrospective single-day assessments, and direct observation (D) involves watching the
person eat.
Q8: Undernutrition is best defined as:
, • A. Consuming too many calories leading to obesity
• B. Consuming insufficient energy, protein, and/or micronutrients to meet physiological
needs [CORRECT]
• C. Consuming excessive amounts of vitamins and minerals
• D. Consuming a diet high in processed foods
Correct Answer: B
Rationale: Undernutrition (B) occurs when nutrient intake is insufficient to meet the body's
needs for energy, protein, or micronutrients. Consuming excess calories (A) describes
overnutrition, excessive vitamins/minerals (C) describes toxicity, and processed foods (D) relates
to diet quality rather than undernutrition.
Q9: Which of the following is classified as an essential nutrient?
• A. Cholesterol synthesized by the liver
• B. Dietary fiber that must be obtained from food [CORRECT]
• C. Vitamin D synthesized from sunlight exposure
• D. Creatine produced in the body
Correct Answer: B
Rationale: Essential nutrients cannot be synthesized by the body in sufficient quantities and
must be obtained from food. While the body can synthesize cholesterol (A), some vitamin D
with sunlight (C), and creatine (D), dietary fiber (B) must be consumed and is essential for
digestive health.
Q10: A health educator is explaining the Dietary Guidelines recommendation to "shift to
healthier food and beverage choices." Which example best demonstrates this principle?
• A. Replacing whole fruit with 100% fruit juice
• B. Choosing whole grain bread instead of white bread [CORRECT]
• C. Selecting full-fat dairy products over low-fat options
• D. Substituting regular soda with diet soda containing artificial sweeteners
Correct Answer: B
