1. A healthy pregnancy depends on all of the following EXCEPT:
A) Adequate vitamin/mineral intake
B) Achieving a very low body fat percentage
C) Controlling existing health conditions
D) Avoiding teratogens
Answer: B
Rationale: A very low body fat percentage can impair fertility and pregnancy
outcomes. Healthy body weight, not extremely low fat, is recommended.
2. Which stage of prenatal development is most sensitive to teratogens?
A) Blastogenic stage
B) Embryonic stage
C) Fetal stage
D) All stages equally

Rationale: The embryonic stage (weeks 2–8) involves organ formation; teratogens
during this period cause major structural birth defects.
3. The placenta is responsible for:
, A) Producing breast milk
B) Exchanging oxygen, nutrients, and wastes between mother and fetus
C) Storing excess glucose for the third trimester
D) Synthesizing fetal red blood cells
Answer: B
Rationale: The placenta facilitates gas and nutrient exchange and removes fetal
wastes via maternal circulation.

Rationale: IOM guidelines recommend 25–35 lb for normal BMI (18.5–24.9) to
reduce risks of low or high birth weight.

A) Increased protein synthesis
B) Ketone production, potentially harming fetal brain
