A nurse is reinforcing teaching with a client who is at 6 weeks of gestation. The client tells the nurse that she smokes one pack of cigarettes per day. The nurse should instruct the client that her newborn is at increased risk for which of the following clinical manifestations?

Choice A rationale: While colostrum is present in the first few days after delivery, it takes a few more days for breast milk to "come in" and increase in volume.
Choice B rationale: Waiting for 6 to 8 days for breast milk to come in would be too long after childbirth. Breast milk typically "comes in" sooner, around 3 to 5 days after delivery.
Choice C rationale: Colostrum, the first milk, is typically produced in small amounts during the first few days after delivery. Breast milk usually "comes in" or increases in volume around 3 to 5 days after childbirth. This transition from colostrum to mature milk is normal and expected.
Choice D rationale: Waiting for 10 days for breast milk to come in would be too long after childbirth. Breast milk typically "comes in" sooner, around 3 to 5 days after delivery.

Choice A rationale: The presence of phosphatidylglycerol (PG) in the amniotic fluid is another indicator of fetal lung maturity. The absence of PG is associated with an increased risk of respiratory distress syndrome (RDS) in the newborn.
Choice B rationale: A nonstress test is a test performed during pregnancy to evaluate the fetal heart rate in response to fetal movement. It is not directly related to assessing fetal lung maturity.
Choice C rationale: The L/S ratio is an important indicator of fetal lung maturity. Lecithin and sphingomyelin are two surfactants present in the lungs, and the ratio of these two substances increases as the fetal lungs mature. An L/S ratio of 2:1 or greater is considered an indication of lung maturity and suggests that the newborn should be able to breathe adequately after birth.
Choice D rationale: The biophysical profile (BPP) is a prenatal ultrasound assessment of the fetus, which includes evaluating fetal movements, breathing, heart rate, and amniotic fluid volume. While a BPP of 8 is a reassuring score, it does not provide direct information about fetal lung maturity.
