Correct Answer is C

Explanation

Choice A rationale

Placenta formation begins shortly after implantation, but it continues to develop throughout the first trimester and into the early second trimester, making it less precise to attribute the

first 8 weeks solely to this process.

Choice B rationale

Fertilization occurs within the first week after ovulation, marking the beginning of pregnancy, but it is a singular event that happens prior to the developmental processes vulnerable to teratogens.

Choice C rationale

Organogenesis is the critical period during which the major organs and structures of the fetus form, typically occurring between the third and eighth weeks of gestation. This is the

time when the fetus is most susceptible to the effects of teratogens, which can cause congenital anomalies.

Choice D rationale

Implantation occurs approximately 6-10 days after fertilization, embedding the blastocyst into the uterine lining. While crucial, it is not the primary period when teratogenic effects are

most significant, as this happens during organogenesis.

Correct Answer is ["B","D","F"]

Explanation

Choice A rationale:

Supplementing with formula is not necessary based on the given information. The baby is voiding and passing stools adequately, indicating proper feeding. Instead, feeding on demand and ensuring frequent breastfeeding will help address any concerns about the baby's weight.

Choice B rationale:

Feeding 8 to 12 times per day and on demand is recommended to ensure adequate milk supply and proper growth and development of the newborn. Frequent feeding helps to establish and maintain milk production.

Choice C rationale:

Using plastic-lined breast pads is not recommended as they can trap moisture and create an environment that promotes nipple irritation and infection. It is better to use breathable, non-plastic-lined breast pads.

Choice D rationale:

It is correct that a newborn's stools should transition from the dark greenish color meconium to a yellow color within a few days as the baby begins digesting breast milk.

Choice E rationale:

Drinking more whole milk does not directly increase a mother's milk supply. Milk supply is primarily regulated by the frequency and efficiency of breastfeeding or pumping.

Choice F rationale:

Expecting the breasts to feel full, warm, and slightly tender when the milk comes in is accurate. This usually occurs around the third or fourth day postpartum and indicates that the milk production process is underway.
