The parents are questioning why their newborn was born deaf when there are no other deaf family members.
At which stage of the pregnancy could the nurse explore possible exposure to a teratogenic agent?
18 weeks after fertilization.
6 weeks after fertilization.
12 weeks after fertilization.
Incomplete question/stem.
The Correct Answer is B
“6 weeks after fertilization.” Teratogens can begin affecting the developing embryo as early as 10 to 14 days after conception 1.
During embryonic development, there are periods when the developing organ systems show more sensitivity to teratogens.
Choice A is incorrect because 18 weeks after fertilization is not the earliest stage of pregnancy when exposure to a teratogenic agent could occur.
Choice C is incorrect because 12 weeks after fertilization is not the earliest stage of pregnancy when exposure to a teratogenic agent could occur.
Choice D is incorrect because this is not an incomplete question/stem.

Explanation
28 to 40 pounds (13 to 18 kilograms).
Women with a low BMI (under 18.5) should gain between 28 to 40 pounds (13 to 18 kilograms) throughout their pregnancy.
Choice A, 15 to 25 pounds (7 to 11 kilograms), is incorrect because it is the recommended weight gain for women who are overweight before pregnancy.
Choice C, 16 to 30 pounds (7.25 to 14 kilograms), is incorrect because it does not fall within the recommended weight gain range for women with a low BMI.
Choice D, 25 to 35 pounds (11 to 16 kilograms), is incorrect because it is the recommended weight gain for women who are at a healthy weight before pregnancy.
