Introduction
This comprehensive assessment evaluates the foundational knowledge, clinical reasoning, and evidence-based
practice competencies required for mastery of Williams' Basic Nutrition and Diet Therapy. The examination tests
the candidate's ability to integrate the principles of nutritional science with the practical application of medical
nutrition therapy across diverse patient populations and clinical conditions. Using a rigorous multiple-choice and
scenario-based format, this assessment challenges the learner to apply critical thinking in nutritional assessment,
dietary planning, and therapeutic interventions for chronic disease management. Success requires proficiency in
,macronutrient and micronutrient metabolism, energy balance, and effective nutrition counseling to optimize
patient outcomes and promote lifelong health.
SECTION ONE: Questions 1–100
Question 1
Which of the following is the primary function of carbohydrates in the human body?
A. To serve as the building blocks for muscle tissue repair.
B. To provide a concentrated source of stored energy and insulation.
C. To provide the body's preferred and most efficient source of energy, particularly for the brain and nervous
system.
D. To act as catalysts for enzymatic reactions in the liver.
🟢 Correct Answer:
C
🔴 RATIONALE:
Carbohydrates, specifically glucose, are the primary and preferred fuel source for the body, especially for the
brain, central nervous system, and red blood cells. The body stores carbohydrates as glycogen in the liver and
muscles for short-term energy. Proteins primarily serve as building blocks for tissue repair (A). Lipids provide
concentrated stored energy and insulation (B). Enzymes (which are proteins, not carbohydrates) are the
biological catalysts.
Question 2
A patient has a body mass index (BMI) of 32.5 kg/m². According to the standard classification, this patient is
categorized as:
A. Normal weight
,B. Overweight
C. Obese Class I
D. Obese Class II
🟢 Correct Answer:
C
🔴 RATIONALE:
The World Health Organization (WHO) and National Institutes of Health (NIH) classify BMI as follows: Normal
weight: 18.5-24.9 kg/m²; Overweight: 25.0-29.9 kg/m²; Obese Class I: 30.0-34.9 kg/m²; Obese Class II: 35.0-39.9
kg/m²; Obese Class III (severe/extreme obesity): ≥40.0 kg/m². A BMI of 32.5 falls squarely within the Obese Class
I range, indicating a moderate risk of comorbidities.
Question 3
Which lipoprotein is primarily responsible for transporting dietary triglycerides from the small intestine to the
liver and peripheral tissues after a meal?
A. Chylomicrons
B. Very-low-density lipoproteins (VLDLs)
C. Low-density lipoproteins (LDLs)
D. High-density lipoproteins (HDLs)
🟢 Correct Answer:
A
🔴 RATIONALE:
Chylomicrons are the largest lipoproteins and are synthesized in the enterocytes of the small intestine. Their
primary function is to transport exogenous (dietary) triglycerides, cholesterol, and fat-soluble vitamins absorbed
from the diet via the lymphatic system into the bloodstream. VLDLs transport endogenous triglycerides from
the liver. LDLs carry cholesterol to tissues, and HDLs transport cholesterol back to the liver.
, Question 4
A patient is diagnosed with iron-deficiency anemia. Which of the following dietary combinations provides the
best source of highly bioavailable heme iron and enhances its absorption?
A. Spinach salad with strawberries and walnuts
B. Whole-wheat toast with butter and jam
C. Lean beef steak with steamed broccoli and a glass of orange juice
D. Lentil soup with a whole-grain roll
🟢 Correct Answer:
C
🔴 RATIONALE:
Heme iron, found in animal flesh (beef, poultry, fish), is absorbed 2 to 3 times more efficiently than non-heme
iron from plant sources (spinach, lentils). The absorption of heme iron is further enhanced by the presence of
vitamin C (ascorbic acid), which is abundant in orange juice and broccoli. Therefore, the combination of a heme
iron source (steak) with a vitamin C source (orange juice) provides the most bioavailable dietary iron.
Question 5
A patient with hypertension is counseled to follow the DASH (Dietary Approaches to Stop Hypertension) diet.
Which of the following food group recommendations is a core component of this eating plan?
A. High intake of full-fat dairy products.
B. Emphasis on fruits, vegetables, and low-fat dairy products, with a reduction in sodium and saturated fat.
C. Increased intake of processed and canned foods.
D. Unrestricted intake of red meat and added sugars.
🟢 Correct Answer:
B
