Comprehensive Mixed Review
1 Which statement best describes resistance exercise?
A It only burns calories during the exact exercise period and has no other benefit
B It should never be used by older adults
C It replaces the need for dietary protein
D It helps preserve or build skeletal muscle and can improve functional capacity
Answer: D. It helps preserve or build skeletal muscle and can improve functional capacity
Explanation: Resistance training stimulates muscle adaptation and can improve strength, function, bone health, and body
composition. It complements, rather than replaces, adequate nutrition.
2 Which change can reduce energy intake without greatly reducing food volume?
A Replace energy-dense foods with vegetables, fruit, broth-based soups, and lean proteins
B Add oil to every food
C Replace water with sugary drinks
D Choose only fried foods
Answer: A. Replace energy-dense foods with vegetables, fruit, broth-based soups, and lean proteins
Explanation: Foods with lower energy density often contain more water and fiber, allowing larger portions for fewer calories
while still providing nutrients.

, 3 A patient with celiac disease wants a grain substitute. Which is naturally gluten-free?
A Spelt
B Quinoa
C Barley
D Rye
Answer: B. Quinoa
Explanation: Quinoa is naturally gluten-free. Barley, rye, and spelt contain gluten and are not appropriate for a strict
gluten-free diet.
4 Which statement about exclusive cow's milk as the main drink in early infancy is correct?
A It should replace formula at 2 months
B It prevents food allergy in all infants
C It is not an appropriate replacement for breast milk or iron-fortified formula during the first year
D It provides ideal iron content for young infants
Answer: C. It is not an appropriate replacement for breast milk or iron-fortified formula during the first year
Explanation: Whole cow's milk is not an appropriate primary beverage replacement for breast milk or iron-fortified formula
during the first year because its nutrient profile does not meet infant needs.
5 Which nutrient combination is especially important for normal bone mineralization?
A Vitamin C and sodium
B Iron and iodine only
C Vitamin B12 and chloride
D Calcium and vitamin D
Answer: D. Calcium and vitamin D
Explanation: Calcium provides mineral for bone, while vitamin D promotes calcium absorption and helps regulate calcium
balance. Both are central to bone health.

, 6 During prolonged fasting, the body increasingly relies on which stored fuel?
A Adipose triglycerides
B Dietary vitamin C
C Bone calcium as the main calorie source
D Water
Answer: A. Adipose triglycerides
Explanation: As glycogen becomes limited during prolonged fasting, the body increasingly mobilizes fatty acids from stored
triglycerides to meet energy needs.
7 A patient reports early satiety. Which approach may help improve intake?
A Eliminating all protein
B Small, frequent, nutrient-dense meals
C One very large meal each day
D Drinking large volumes immediately before every meal
Answer: B. Small, frequent, nutrient-dense meals
Explanation: Small, frequent meals can be easier to tolerate when fullness occurs quickly. Nutrient density helps maximize
energy and protein intake in smaller volumes.
8 A food label lists 10 g of protein, 20 g of carbohydrate, and 5 g of fat. Approximately how many
kilocalories does the food provide from these three macronutrients?
A 165 kcal
B 205 kcal
C 125 kcal
D 145 kcal
Answer: A. 165 kcal
Explanation: Protein contributes 40 kcal (10 x 4), carbohydrate contributes 80 kcal (20 x 4), and fat contributes 45 kcal (5 x
9). The total is approximately 165 kcal.
