What statement best reflects the energy requirement per kilogram body weight for a healthy newborn compared to an adult?
- A Adults require about 80 kcal/kg/day; newborns about 25 kcal/kg/day
- B Newborns require about 100 kcal/kg/day; adults about 25-30 kcal/kg/day
- C Newborns require about 30 kcal/kg/day; adults about 100 kcal/kg/day
- D Energy requirement per kg is the same for newborns and adults
Correct answer: Newborns require about 100 kcal/kg/day; adults about 25-30 kcal/kg/day
Infants have very high caloric needs per kg (around 100 kcal/kg/day) because of rapid growth and metabolism; adults require only about 25-30 kcal/kg/day.
For infants from birth to 6 months, what is the best feeding recommendation?
- A Cow's milk as the sole source of nutrition
- B Exclusive breastfeeding, or iron-fortified formula
- C A mix of solids, cow's milk and fruit juice
- D Feeding on alternate days to prevent overfeeding
Correct answer: Exclusive breastfeeding, or iron-fortified formula
The recommendation is exclusive breastfeeding for about the first 6 months; if breast milk is unavailable then iron‐fortified formula is used.
During adolescence (ages ~14-18), which nutrition need is especially increased compared to earlier childhood?
- A Requirements fall because the growth rate slows
- B Energy, protein, calcium and iron rise with the growth spurt
- C Only fluid intake rises while other needs stay flat
- D Micronutrient needs drop abruptly to adult levels
Correct answer: Energy, protein, calcium and iron rise with the growth spurt
Adolescents undergo rapid growth and development, so energy, protein, calcium and iron needs are higher than in younger children.
A middle-aged adult (ages ~31-50) should focus on which dietary adjustment?
- A Eat unlimited calories without watching sodium intake
- B Lower calories to match metabolism and prevent chronic disease
- C Raise simple-sugar intake to keep energy levels up
- D Choose foods by calories alone, not nutrient density
Correct answer: Lower calories to match metabolism and prevent chronic disease
As adults enter middle age, metabolism often slows and risks for chronic disease rise, so adjusting caloric intake and focusing on nutrient-rich food is important.
Which micronutrient requirement is increased during pregnancy compared to non-pregnant adults?
- A No micronutrient needs change during pregnancy
- B Iron, folate and DHA rise to support fetal growth
- C Only calcium needs fall below non-pregnant levels
- D Vitamin C requirements drop sharply in pregnancy
Correct answer: Iron, folate and DHA rise to support fetal growth
Pregnancy increases demands for nutrients such as iron, folate and omega-3 fatty acids (DHA) to support fetal and maternal needs.
A toddler (ages 1-3) typically needs what type of dietary fat percentage compared to older children?
- A A lower fat percentage than older children need
- B A higher fat percentage to support brain development
- C The same fat percentage recommended for adults
- D A near-zero fat intake to prevent weight gain
Correct answer: A higher fat percentage to support brain development
Toddlers should have a higher percentage of dietary fat (e.g., 30-35%) for brain development, compared to older children whose fat intake may be lower.
An older adult (age 65+) faces which nutritional challenge unique to this stage?
- A A higher basal metabolic rate than younger adults
- B Reduced appetite, chewing/swallowing and absorption changes
- C Unchanged nutrient absorption compared with youth
- D A need to roughly double daily protein intake
Correct answer: Reduced appetite, chewing/swallowing and absorption changes
Older adults often face physiological changes such as decreased appetite, dental issues, reduced nutrient absorption and must focus on nutrient density.
For infants around 6 months of age, what new nutritional milestone should be addressed?
- A Continue breast milk alone with no solid foods yet
- B Introduce complementary solids while continuing breast milk
- C Switch fully to cow's milk in place of breast milk
- D Delay any solid foods until about two years of age
Correct answer: Introduce complementary solids while continuing breast milk
Around 6 months, many infants are ready for complementary foods in addition to breast milk or formula to meet increasing nutrient needs.
When planning nutrition for school-aged children (~6-12 years), what is an important guiding principle?
- A No need to watch added sugar or saturated fat intake
- B Stress nutrient-dense foods and limit added sugar and fat
- C Track total calories alone, not overall nutrient quality
- D Feed the same diet portions used for toddlers
Correct answer: Stress nutrient-dense foods and limit added sugar and fat
At this stage, children still grow but risks of overweight/obesity increase, so diet quality (nutrient density) and limiting added sugars and saturated fats are critical.
A newborn born preterm will have higher nutritional needs because:
- A They grow more slowly and so need fewer nutrients
- B They need more energy per kg and have less reserve
- C They need fewer calories overall because they are small
- D They need only formula, not added protein or micronutrients
Correct answer: They need more energy per kg and have less reserve
Preterm infants need higher energy and nutrient intakes per kg due to rapid catch-up growth and less reserve of fat and protein.
A young adult (ages ~19-30) should emphasise which dietary focus?
- A A high-calorie, low-nutrient convenience diet
- B A balanced nutrient-dense diet supporting long-term health
- C Skipping meals frequently to control overall intake
- D A protein-only focus that neglects other nutrients
Correct answer: A balanced nutrient-dense diet supporting long-term health
Young adults have reached physical peak but still must establish healthy patterns: nutrient-dense food, maintaining weight, preventing excess fat, and preparing for long-term health.
Which statement best describes calorie needs per kg bodyweight as children age?
- A They remain constant from infancy through old age
- B They fall markedly after infancy as growth slows
- C They rise steadily on through the adult years
- D They reach their peak in later older adulthood
Correct answer: They fall markedly after infancy as growth slows
Caloric requirement per kg is highest in infancy and declines as growth rate slows; e.g., infants may need ~100 kcal/kg/day vs older children much less.
During adolescence, iron requirements increase significantly especially in which group?
- A Male adolescents because of rapid muscle gain
- B Female adolescents due to menstruation
- C Older adults due to declining intake
- D Toddlers during slowed growth phases
Correct answer: Female adolescents due to menstruation
Female adolescents have increased iron needs due to the onset of menstruation in addition to growth, making iron a critical nutrient.
Which nutrient is especially important for bone health in adolescence to support peak bone mineralization?
- A Vitamin C for collagen synthesis
- B Calcium and vitamin D
- C Sodium for fluid balance
- D Excess dietary protein intake
Correct answer: Calcium and vitamin D
Adolescents undergo rapid skeletal growth, and adequate calcium and vitamin D are essential to reach peak bone mass and prevent osteoporosis later.
In pregnancy, total weight gain is important. Which statement is accurate?
- A No weight gain is needed during a healthy pregnancy
- B Recommended gain varies by pre-pregnancy BMI
- C Any gain above 20 kg is ideal for the fetus
- D Only maternal fat stores matter, not fetal growth
Correct answer: Recommended gain varies by pre-pregnancy BMI
Pregnancy nutritional needs include weight gain guidelines based on pre-pregnancy BMI to support fetal growth and maternal nutrient stores.
Which dietary pattern is recommended across the lifespan to support healthy growth and reduce chronic disease risk?
- A A diet high in added sugar and saturated fat at all ages
- B A nutrient-dense pattern of vegetables, fruits, and whole grains
- C Skipping fruits and vegetables entirely after adolescence
- D Using identical food portions for infants and adults
Correct answer: A nutrient-dense pattern of vegetables, fruits, and whole grains
According to guidelines, a healthy dietary pattern rich in nutrient-dense foods and limited in added sugars and saturated fats is recommended at every life stage.
For older adults, protein needs may need to be:
- A Lowered sharply to prevent kidney damage
- B Maintained or slightly increased to preserve muscle mass
- C Eliminated completely to reduce calorie load
- D Replaced entirely by dietary fats and oils
Correct answer: Maintained or slightly increased to preserve muscle mass
Older adults may require adequate or slightly higher protein to preserve muscle mass (sarcopenia prevention) even as total calories may decrease.
A toddler who eats fewer calories than previous years likely needs:
- A Keep the same large portions used during infancy
- B Smaller, nutrient-dense portions as growth velocity slows
- C Roughly triple the calorie intake of an infant
- D Withhold all solid foods until later childhood
Correct answer: Smaller, nutrient-dense portions as growth velocity slows
Growth slows in toddlerhood compared to infancy; therefore portion sizes may decrease but nutrient density remains critical to meet needs with fewer calories.
Which statement is true about hydration and micronutrients in older adulthood?
- A Older adults rarely have any altered fluid needs
- B Reduced thirst and absorption raise attention to fluids and micronutrients
- C Only calories matter in old age, not fluids or micronutrients
- D Hydration needs disappear entirely after age 60
Correct answer: Reduced thirst and absorption raise attention to fluids and micronutrients
Older adults often experience changes such as reduced thirst, impaired absorption and lower appetite, so monitoring fluid intake and micronutrient adequacy is essential.
Which of the following is a correct example of tailoring nutrition to a life stage?
- A Feeding an adult on the same schedule and composition as an infant
- B Introducing iron-rich complementary foods at about 6 months
- C Having an adolescent eat only half the calories of a toddler
- D Ignoring nutrient quality entirely across all life stages
Correct answer: Introducing iron-rich complementary foods at about 6 months
At about 6 months infants’ iron stores from birth begin to deplete, so introduction of iron-rich complementary foods is an age-specific nutritional adaptation.
