Nutrition. This module typically covers foundational nutrition principles,
macronutrients, micronutrients, energy calculations, dietary guidelines, digestion
and absorption, and nutrition assessment. These are not official examination
questions and are not copied from any textbook, test bank, or copyrighted source.
Question 1:
Which nutrient is the body’s preferred source of energy for the brain and red blood cells?
A. Protein
B. Fat
C. Carbohydrate
D. Water
Correct answer: C
Rationale:
Carbohydrates are broken down into glucose, which is the preferred energy source for
the brain and red blood cells.
Question 2:
A kilocalorie is a unit that measures:
A. Body weight
B. Energy supplied by food
C. Protein quality
D. Water balance
Correct answer: B
Rationale:
A kilocalorie measures the energy content of food and the energy used by the body.
Question 3:
An essential nutrient is one that:
A. The body can make in sufficient amounts
B. Must be obtained from food
C. Is needed only during illness
D. Is found only in supplements
,Correct answer: B
Rationale:
Essential nutrients cannot be made by the body in adequate amounts and must come
from the diet.
Question 4:
Which grouping lists only macronutrients?
A. Vitamins, minerals, water
B. Carbohydrates, proteins, fats
C. Phytochemicals, zoochemicals, fiber
D. Iron, calcium, zinc
Correct answer: B
Rationale:
Macronutrients are needed in large amounts and include carbohydrates, proteins, and
fats.
Question 5:
Which grouping lists only micronutrients?
A. Carbohydrates and proteins
B. Fats and water
C. Vitamins and minerals
D. Starch and glycogen
Correct answer: C
Rationale:
Micronutrients are vitamins and minerals, required in smaller amounts.
Question 6:
Which nutrients are organic?
A. Water and minerals
B. Carbohydrates, lipids, proteins, and vitamins
C. Minerals and oxygen
D. Water and oxygen
Correct answer: B
,Rationale:
Organic nutrients contain carbon. Carbohydrates, lipids, proteins, and vitamins are
organic.
Question 7:
Carbohydrates and proteins provide approximately how many kilocalories per gram?
A. 2
B. 4
C. 7
D. 9
Correct answer: B
Rationale:
Carbohydrates and proteins each provide about 4 kcal per gram.
Question 8:
Fat provides approximately how many kilocalories per gram?
A. 4
B. 7
C. 9
D. 12
Correct answer: C
Rationale:
Fat provides about 9 kcal per gram, making it the most energy-dense macronutrient.
Question 9:
A snack contains 10 g carbohydrate, 5 g protein, and 5 g fat. What is the total energy?
A. 95 kcal
B. 105 kcal
C. 115 kcal
D. 125 kcal
Correct answer: B
Rationale:
(10 × 4) + (5 × 4) + (5 × 9) = 40 + 20 + 45 = 105 kcal.
, Question 10:
Nutrient density refers to:
A. The amount of nutrients per calorie in a food
B. The weight of a food
C. The number of calories per gram
D. The amount of water in a food
Correct answer: A
Rationale:
Nutrient density compares nutrient content to calorie content.
Question 11:
Which is a monosaccharide?
A. Sucrose
B. Lactose
C. Glucose
D. Maltose
Correct answer: C
Rationale:
Glucose is a single sugar unit, or monosaccharide.
Question 12:
Sucrose is classified as a:
A. Monosaccharide
B. Disaccharide
C. Polysaccharide
D. Fiber
Correct answer: B
Rationale:
Sucrose is a disaccharide made of glucose and fructose.
Question 13:
Which is a polysaccharide?
