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
The nurse should check for blood under the client’s buttocks.
A small amount of lochia rubra on the client’s perineal pad 4 hours postpartum is normal.
The fundus being midline and firm at the umbilicus is also a normal finding.
Choice A is incorrect because assisting the client to ambulate is not necessary at this time.
Choice B is incorrect because there is no need to increase the rate of IV fluids.
Choice D is incorrect because performing a fundal massage is not necessary since the fundus is already firm and midline.
Correct Answer is C
Explanation
The MSAFP test measures the levels of alpha-fetoprotein (AFP) in the mother’s body.
AFP is a protein produced by the baby during pregnancy.
Too much AFP in the mother’s body may indicate that the baby is at risk of a neural tube defect, like spina bifida.
Choice A is incorrect because this test does not screen for gestational diabetes.
Choice B is incorrect because this test does not screen for fetal maturity.
Choice D is incorrect because this test does not screen for ABO incompatibility.
