**Question:** Energy requirement in late pregnancy for a moderate worker is

A. 3400 kcal/day
B. 3000 kcal/day
C. 2800 kcal/day
D. 3200 kcal/day

**Core Concept:** Energy requirements in pregnancy are increased due to the needs of the growing fetus, placental, and maternal tissues. The energy needs depend on factors like maternal age, weight, height, pre-pregnancy body mass index (BMI), activity level, and trimester.

**Why the Correct Answer is Right:** The correct answer (D) represents the average daily energy requirement for a moderate woman in late pregnancy (3rd trimester). Energy requirements increase as pregnancy progresses due to the growing fetus, placenta, and maternal tissues. In the third trimester, the average woman requires approximately 3200 kcal/day.

**Why Each Wrong Option is Incorrect:**

A (3400 kcal/day) is too high, as it exceeds the actual energy requirements for a moderate woman during late pregnancy.

B (3000 kcal/day) is slightly lower than the correct answer but still not accurate for a moderate woman in late pregnancy.

C (2800 kcal/day) is too low, as it does not account for the increased energy needs during the third trimester.

**Clinical Pearl:** Late pregnancy is characterized by increased energy requirements due to the growing fetus and maternal tissues. The correct answer (3200 kcal/day) represents the average energy needs of a moderate woman during this stage. Monitoring and managing energy intake can help maintain maternal health and fetal well-being.

**Correct Answer:** D (3200 kcal/day)
