Section 1: Energy & Weight Gain (Questions 1–
10)
1. How many additional daily calories are
recommended during the FIRST trimester of
pregnancy?
• ☑VERIFIED ANSWER: 0 kcal (No additional
calories)
• Rationale: During the first trimester, fetal
growth is minimal, and maternal energy

needs do not significantly increase. The
extra calories are needed in the 2nd and 3rd
trimesters when fetal growth accelerates.
2. How many additional daily calories are
recommended during the SECOND trimester?
• ☑VERIFIED ANSWER: +340 kcal/day
• Rationale: Fetal growth and maternal tissue
expansion (placenta, amniotic fluid,
increased blood volume) ramp up during
the second trimester, requiring this
moderate increase in energy intake.
3. How many additional daily calories are
recommended during the THIRD trimester?
• ☑VERIFIED ANSWER: +450 kcal/day
• Rationale: This is the period of fastest fetal
weight gain and fat deposition, demanding

the highest caloric increase of the
pregnancy.
4. What is the recommended total weight gain
for a woman with a normal pre-pregnancy BMI
(18.5–24.9)?
• ☑VERIFIED ANSWER: 25–35 pounds (11.5–
16 kg)
• Rationale: The IOM guidelines base weight
gain recommendations on pre-pregnancy
BMI. Normal-weight women need this range
to support fetal growth while minimizing
pregnancy complications.
5. What is the recommended weight gain for
the FIRST trimester specifically?
• ☑VERIFIED ANSWER: 0.5 – 2.0 kg (1 – 4.5
lbs)
