A nurse is caring for a newborn who is small for gestational age. Which of the following findings is associated with this condition?

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.

Choice A rationale:
Craniofacial abnormalities are not directly associated with maternal smoking during pregnancy. However, smoking during pregnancy can have other adverse effects on the baby's development.
Choice B rationale:
Maternal smoking during pregnancy is a significant risk factor for delivering a baby with low birth weight. Smoking can lead to restricted blood flow to the placenta, affecting the baby's growth and development.
Choice C rationale:
Hypersensitivity to noise is not a common clinical manifestation associated with maternal smoking during pregnancy.
Choice D rationale:
Hyperactivity is not a common clinical manifestation associated with maternal smoking during pregnancy. However, smoking during pregnancy can have other effects on the child's behavior and development later in life.
