WILLIAMS' BASIC NUTRITION & DIET THERAPY EXAM
WITH VERIFIED ANSWERS DETAILED RATIONALES
GRADED A+
Williams' Basic Nutrition & Diet Therapy
SECTION 1: FOOD, NUTRITION & HEALTH (Questions 1–30)
1. The Dietary Reference Intakes (DRIs) are developed by which organization?
A. U.S. Public Health Service
B. Food and Drug Administration (FDA)
C. National Academy of Sciences
D. Department of Agriculture (USDA)
Rationale: The DRIs are developed by the National Academy of Sciences' Institute of Medicine
(now National Academy of Medicine). They provide quantitative estimates of nutrient intakes
for healthy populations.
2. When not enough scientific evidence is available to establish a Recommended Dietary
Allowance (RDA), which value is used to guide intake?
A. Adequate Intake (AI)
B. Estimated Average Requirement (EAR)
C. Tolerable Upper Intake Level (UL)
D. Acceptable Macronutrient Distribution Range (AMDR)
1|Page
,Page 2 of 83
Rationale: The Adequate Intake (AI) is set when there is insufficient evidence to establish an
EAR and, therefore, an RDA. It is a recommended average daily intake level based on observed
or experimentally determined approximations.
3. The sum of all body processes inside living cells that sustain life and health is:
A. Digestion
B. Metabolism
C. Absorption
D. Catabolism
Rationale: Metabolism encompasses all chemical reactions in the body that sustain life,
including catabolism (breakdown) and anabolism (synthesis). Digestion and absorption are
specific processes within the broader metabolic framework.
4. Which of the following is an example of a functional food?
A. White bread
B. Oatmeal with added plant sterols
C. Candy bar
D. Soda
Rationale: Functional foods provide health benefits beyond basic nutrition. Oatmeal with added
plant sterols, which can help lower cholesterol, is an example of a functional food.
5. The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates is:
A. 10%–35%
B. 20%–35%
C. 45%–65%
D. 50%–70%
Rationale: The AMDR for carbohydrates is 45%–65% of total daily calories. The AMDR for fat is
20%–35%, and for protein it is 10%–35%.
6. A patient requires a nutrition assessment. Which of the following is NOT a component of a
comprehensive nutrition assessment?
2|Page
,Page 3 of 83
A. Anthropometric measurements
B. Biochemical data
C. Clinical examination
D. Financial status
Rationale: A comprehensive nutrition assessment includes anthropometric measurements,
biochemical data, clinical examination, and dietary intake. Financial status is a social
determinant of health but is not a direct component of nutrition assessment.
7. The health care professional who is responsible for overseeing the nutrition care of patients
in a hospital setting is a:
A. Physician
B. Registered dietitian nutritionist (RDN)
C. Nurse
D. Pharmacist
Rationale: Registered dietitian nutritionists (RDNs) are the health care professionals responsible
for overseeing the nutrition care of patients, including nutrition assessment, diagnosis,
intervention, and monitoring.
8. Which of the following is a primary function of nutrients?
A. Providing energy
B. Building and repairing tissues
C. Regulating body processes
D. All of the above
Rationale: Nutrients provide energy, build and repair tissues, and regulate body processes. All
of these are primary functions of nutrients.
9. The leading cause of death in the United States is:
A. Infectious disease
B. Heart disease
3|Page
, Page 4 of 83
C. Accidents
D. Cancer
Rationale: Heart disease is the leading cause of death in the United States. Diet plays a
significant role in the development of heart disease and other chronic conditions.
10. Which of the following best describes a nutrient-dense food?
A. A food that provides a high amount of nutrients relative to its calorie content
B. A food that provides a high amount of calories relative to its nutrient content
C. A food that is high in sugar
D. A food that is high in fat
Rationale: A nutrient-dense food provides a high amount of vitamins, minerals, and other
beneficial compounds relative to its calorie content. Examples include fruits, vegetables, and
whole grains.
11. Promoting a health care service that improves diabetes management for the elderly in a
community would assist in which of the following?
A. Supporting the national health goals Healthy People 2030
B. Reducing hunger in a subset of the United States population
C. Reducing health care costs
D. Improving food security
Rationale: Improving diabetes management for elderly individuals in a community supports the
national health goals of Healthy People 2030, which aim to improve health and prevent disease.
This initiative also addresses health care costs and food security, but the primary alignment is
with national health goals.
12. A nutrient that must be supplied by the diet because the body cannot make it in sufficient
quantities is called:
A. Nonessential nutrient
B. Essential nutrient
