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). Eliminating all carbohydrates (B) is not
recommended as they are the body's primary energy source. Saturated fats should be limited to
less than 10% of calories (C). Dietary fiber is essential for digestive health and should be
consumed daily (D).
Q2: Which component of the nutrition assessment acronym "ABCD" involves measuring height,
weight, BMI, and waist circumference?
• A. Biochemical
• B. Anthropometric [CORRECT]
• C. Clinical
• D. Dietary
Correct Answer: B Rationale: Anthropometric assessment (B) involves physical measurements
including height, weight, BMI, and waist circumference to evaluate body composition and
nutritional status. Biochemical (A) involves laboratory tests, Clinical (C) involves physical
examination, and Dietary (D) involves diet history and food intake assessment.
,Q3: According to MyPlate recommendations, which food group should occupy the largest
proportion of your plate?
• A. Protein
• B. Grains
• C. Vegetables [CORRECT]
• D. Dairy
Correct Answer: C Rationale: MyPlate recommends that vegetables (C) and fruits together
should make up half of the plate, with vegetables typically occupying the largest proportion.
Protein (A) and grains (B) each occupy about a quarter of the plate, while dairy (D) is
represented as a side portion.
Q4: A client states they avoid all fruits because they contain "too much sugar." Which
educational response best addresses this misconception?
• A. Fruits contain only artificial sugars that don't affect blood glucose
• B. Fruits contain naturally occurring sugars along with fiber, vitamins, and minerals that
provide health benefits [CORRECT]
• C. All sugars are harmful regardless of source
• D. Fruits should be eliminated from a healthy diet
Correct Answer: B Rationale: Fruits contain naturally occurring sugars packaged with fiber,
vitamins, minerals, and phytochemicals that provide significant health benefits (B). The fiber in
fruits slows sugar absorption and promotes satiety. Naturally occurring sugars in whole fruits are
fundamentally different from added sugars (A, C are incorrect). Fruits are essential components
of a healthy eating pattern (D is incorrect).
Q5: Which factor influencing food choices is demonstrated when a person selects foods based on
religious dietary laws?
• A. Personal preference
• B. Cultural influence [CORRECT]
• C. Economic factor
• D. Environmental factor
,Correct Answer: B Rationale: Religious dietary laws represent cultural influences (B) on food
choices, as they are learned through family and community traditions. Personal preference (A)
refers to individual taste likes and dislikes. Economic factors (C) involve cost and accessibility,
while environmental factors (D) include food availability and sustainability concerns.
Q6: Which dietary assessment method involves asking a client to record all foods and beverages
consumed over a 3-7 day period?
• A. 24-hour recall
• B. Food frequency questionnaire
• C. Food diary/record [CORRECT]
• D. Diet history interview
Correct Answer: C Rationale: A food diary or record (C) requires clients to prospectively
record all foods and beverages consumed over multiple days (typically 3-7), providing detailed
intake data. A 24-hour recall (A) asks about intake from the previous day only. A food frequency
questionnaire (B) assesses how often foods are consumed over longer periods. A diet history (D)
is a comprehensive interview about usual eating patterns.
Q7: According to the Dietary Guidelines for Americans, which of the following best describes a
healthy eating pattern?
• A. Focus on variety, nutrient density, and amount [CORRECT]
• B. Eliminate all food groups containing carbohydrates
• C. Consume unlimited amounts of sodium for proper hydration
• D. Avoid all fats to prevent heart disease
Correct Answer: A Rationale: The Dietary Guidelines emphasize focusing on variety, nutrient
density, and amount (A) across all food groups. Carbohydrates (B) are essential macronutrients
that should not be eliminated. Sodium should be limited to less than 2,300 mg/day (C). Healthy
fats are essential for bodily functions and should be included in moderation (D).
Q8: A nutritionist is conducting a clinical assessment. Which finding would indicate a potential
vitamin C deficiency?
• A. Night blindness
, • B. Bleeding gums and poor wound healing [CORRECT]
• C. Beriberi
• D. Pellagra
Correct Answer: B Rationale: Bleeding gums and poor wound healing (B) are classic signs of
scurvy caused by vitamin C deficiency, as vitamin C is essential for collagen synthesis. Night
blindness (A) indicates vitamin A deficiency. Beriberi (C) results from thiamin (B1) deficiency.
Pellagra (D) is caused by niacin (B3) deficiency.
Q9: Which of the following represents a form of malnutrition characterized by excessive energy
intake relative to needs?
• A. Undernutrition
• B. Overnutrition [CORRECT]
• C. Marasmus
• D. Kwashiorkor
Correct Answer: B Rationale: Overnutrition (B) is a form of malnutrition characterized by
excessive energy intake leading to overweight or obesity. Undernutrition (A) refers to inadequate
nutrient intake. Marasmus (C) is severe protein-energy undernutrition with wasting. Kwashiorkor
(D) is severe protein deficiency with edema despite adequate calories.
Q10: A client asks about the difference between essential and non-essential nutrients. Which
explanation is most accurate?
• A. Essential nutrients can be synthesized by the body; non-essential must be obtained
from food
• B. Essential nutrients must be obtained from food; non-essential can be synthesized by
the body [CORRECT]
• C. Non-essential nutrients are not needed for bodily functions
• D. Essential nutrients are only vitamins and minerals
Correct Answer: B Rationale: Essential nutrients (B) cannot be synthesized by the body in
sufficient quantities and must be obtained from food. Non-essential nutrients can be synthesized
by the body. Both essential and non-essential nutrients are needed for bodily functions (C is
incorrect). Essential nutrients include carbohydrates, proteins, fats, vitamins, minerals, and water
(D is incomplete).
