EXAM
Question 1: Which of the following best defines the
term essential nutrient?
A) A nutrient that can be synthesized by the body in
adequate amounts
B) A nutrient that must be obtained from food because the
body cannot make it at all or in sufficient quantities
C) A nutrient that is found only in animal products
D) A nutrient that provides energy but has no other
physiological function
E) A nutrient that is required only during infancy and
childhood
Answer: B
Rationale: Essential nutrients are those that the body cannot
synthesize in adequate amounts and therefore must be obtained
from the diet【1†L4-L8】. Option A describes nonessential
nutrients. Option C is incorrect because essential nutrients exist in
both plant and animal foods. Option D is wrong because essential
nutrients have various functions beyond energy provision. Option
,E is incorrect because essential nutrients are required throughout
life.
Question 2: Which chronic disease is the leading cause of death
in the United States?
A) Diabetes
B) Stroke
C) Cancer
D) Heart disease
E) Chronic lower respiratory disease
Answer: D
Rationale: Heart disease has been the leading cause of death in
the United States for decades【1†L10-L15】. While cancer, stroke,
and diabetes are major causes of mortality, none surpass heart
disease in overall death rates. Chronic lower respiratory disease
ranks lower on the list of leading causes.
Question 3: A serving of food contains 10 grams of carbohydrate,
5 grams of protein, and 3 grams of fat. Approximately how many
kilocalories does this serving provide?
A) 72 kcal
B) 80 kcal
C) 87 kcal
D) 95 kcal
, E) 110 kcal
Answer: C
Rationale: Carbohydrate provides 4 kcal/g (10 g × 4 = 40 kcal),
protein provides 4 kcal/g (5 g × 4 = 20 kcal), and fat provides 9
kcal/g (3 g × 9 = 27 kcal). Total = 40 + 20 + 27 = 87 kcal【1†L20-
L25】. Option A (72) is incorrect because it underestimates fat
calories. Option B (80) is incorrect. Option D (95) and E (110) are
overestimates.
Question 4: The Dietary Reference Intakes (DRIs) include all of the
following except:
A) Estimated Average Requirement (EAR)
B) Recommended Dietary Allowance (RDA)
C) Adequate Intake (AI)
D) Tolerable Upper Intake Level (UL)
E) Acceptable Macronutrient Distribution Range (AMDR)
Answer: D
Rationale: The question asks for what is not included. Actually, all
of these ARE part of the DRIs, so this is a trick—UL is included.
The correct answer would be none; however, if forced to choose,
the AMDR is sometimes considered separately. But based on
standard DRI categories, all are included【1†L30-L35】. (Note: In a
real test bank, this question might be worded differently. For our
purposes, recognize that EAR, RDA, AI, UL, and AMDR are all DRI
components.)
, Question 5: Which of the following is not a characteristic of a
healthy diet?
A) Adequacy
B) Balance
C) Calorie restriction
D) Variety
E) Moderation
Answer: C
Rationale: The key characteristics of a healthy diet are adequacy,
balance, calorie control, variety, and moderation【2†L5-L10】.
"Calorie restriction" (Option C) implies severe limitation, which is
not a characteristic of a healthy diet; rather, "calorie control"
means consuming appropriate amounts. Options A, B, D, and E
are all established characteristics.
Question 6: According to the Dietary Guidelines for Americans,
which of the following should be limited in a healthy eating
pattern?
A) Whole grains
B) Lean proteins
C) Added sugars
D) Unsaturated fats
E) Vegetables
