Module 1: Principles of Nutrition, Energy Balance & Assessment (Questions 1–18)
Question 1
Which macronutrient delivers 9 kilocalories per gram, providing the highest caloric density in the
human diet?
• A) Carbohydrates
• B) Lipids (Fats)
• C) Proteins
• D) Alcohol
Correct Answer: B) Lipids (Fats)
Lipids yield 9 kcal/g, whereas carbohydrates and proteins yield 4 kcal/g, and alcohol yields 7 kcal/g.
Question 2
A client consumes 60 grams of carbohydrates, 20 grams of protein, and 15 grams of fat. What is
the total caloric intake provided by this meal?
• A) 380 kcal
• B) 455 kcal
• C) 515 kcal
• D) 620 kcal
Correct Answer: B) 455 kcal
Calculation: (60g carbs × 4 kcal/g = 240) + (20g protein × 4 kcal/g = 80) + (15g fat × 9 kcal/g = 135) = 240 + 80 +
135 = 455 kcal.
,Question 3
Which component accounts for the largest percentage of Total Daily Energy Expenditure
(TDEE) in a sedentary adult?
• A) Thermic Effect of Food (TEF)
• B) Basal Metabolic Rate (BMR)
• C) Physical Activity Energy Expenditure (PAEE)
• D) Non-Exercise Activity Thermogenesis (NEAT)
Correct Answer: B) Basal Metabolic Rate (BMR)
Basal Metabolic Rate accounts for 60%–75% of total daily energy expenditure to maintain vital bodily
functions at rest.
Question 4
What serum protein biomarker, despite being affected by systemic inflammation, has
traditionally served as a short-term indicator of acute nutritional status due to its half-life of
approximately 2 days?
• A) Serum Albumin
• B) Prealbumin (Transthyretin)
• C) Transferrin
• D) Retinol-binding protein
Correct Answer: B) Prealbumin (Transthyretin)
Prealbumin has a short half-life of 2 days, making it more sensitive to acute changes in protein intake than
albumin, which has a 20-day half-life.
Question 5
Which Anthropometric measurement is used to assess visceral adiposity and independent
cardiovascular disease risk?
• A) Mid-arm muscle circumference
• B) Waist circumference
• C) Triceps skinfold thickness
• D) Head-to-heel length ratio
Correct Answer: B) Waist circumference
Waist circumference (>40 inches in men, >35 inches in non-pregnant women) directly measures abdominal
visceral fat and correlates with cardiometabolic risk.
Question 6
A client has a height of 1.75 meters and a weight of 85 kilograms. What is the client's calculated
Body Mass Index (BMI) and classification?
• A) 24.2 kg/m² (Normal Weight)
• B) 27.8 kg/m² (Overweight)
• C) 31.4 kg/m² (Obesity Class I)
• D) 35.0 kg/m² (Obesity Class II)
Correct Answer: B) 27.8 kg/m² (Overweight)
BMI = weight (kg) / [height (m)]² = 85 / (1.75)² = .0625 = 27.75 kg/m², which falls in the Overweight range
(25.0–29.9 kg/m²).
, Question 7
Which vitamin deficiency manifests as Wernicke-Korsakoff syndrome in chronic alcohol
dependency?
• A) Vitamin B1 (Thiamine)
• B) Vitamin B3 (Niacin)
• C) Vitamin B12 (Cobalamin)
• D) Vitamin C (Ascorbic Acid)
Correct Answer: A) Vitamin B1 (Thiamine)
Thiamine deficiency impairs carbohydrate metabolism in neural tissue, causing Wernicke-Korsakoff
encephalopathy and psychosis.
Question 8
What classical deficiency disease presents with the "4 Ds" (Dermatitis, Diarrhea, Dementia, and
Death)?
• A) Beriberi
• B) Pellagra (Niacin deficiency)
• C) Scurvy
• D) Rickets
Correct Answer: B) Pellagra (Niacin deficiency)
Pellagra results from severe Vitamin B3 (Niacin) or tryptophan deficiency and manifests as dermatitis,
diarrhea, dementia, and death if untreated.
Question 9
Which essential fatty acid must be obtained through dietary sources because the human body
cannot synthesize omega-3 fatty acids de novo?
• A) Oleic acid
• B) Alpha-linolenic acid (ALA)
• C) Palmitic acid
• D) Stearic acid
Correct Answer: B) Alpha-linolenic acid (ALA)
Alpha-linolenic acid (omega-3) and linoleic acid (omega-6) are essential fatty acids that humans lack
desaturase enzymes to synthesize.
Question 10
Which fat-soluble vitamin plays a critical role in the synthesis of blood clotting factors II, VII, IX,
and X?
• A) Vitamin A
• B) Vitamin D
• C) Vitamin E
• D) Vitamin K
Correct Answer: D) Vitamin K
Vitamin K serves as an essential cofactor for gamma-glutamyl carboxylase, enabling functional activation of
