Along with gas exchange and nutrient transfer, the placenta produces many hormones necessary for normal pregnancy.
These include (select all that apply):
Human chorionic gonadotropin (hCG).
Testosterone.
Insulin.
Estrogen.
Progesterone.
Correct Answer : A,D,E
Choice A rationale
Human chorionic gonadotropin (hCG) is produced by the placenta, maintaining the corpus luteum and promoting progesterone production crucial for sustaining pregnancy.
Choice B rationale
Testosterone is not produced by the placenta; it is primarily synthesized in the testes and ovaries and not involved in normal pregnancy hormone production.
Choice C rationale
Insulin is not produced by the placenta; instead, it is secreted by the pancreas and regulates blood glucose levels, not directly linked to pregnancy hormones.
Choice D rationale
Estrogen is produced by the placenta, contributing to the development of female secondary sexual characteristics and maintaining the uterine lining during pregnancy.
Choice E rationale
Progesterone is produced by the placenta, supporting the uterine lining's maintenance, preventing contractions, and creating a suitable environment for fetal development.

Correct Answer is B
Explanation
Choice A rationale
Calculating from the LMP of February 14, 2019, the estimated date of birth using Naegele's rule would not fall in September.
Choice B rationale
Using Naegele's rule, adding 7 days to February 14 results in February 21, 2019, then subtracting 3 months, results in November 2019.
Choice C rationale
Naegele's rule calculates EDB by adding 7 days to the LMP and then subtracting 3 months. This does not lead to a November date.
Choice D rationale
While close, November 7 is not accurate. Naegele's rule would adjust from February 14, giving an EDB in mid to late November.
