A nurse is educating the mother of a newborn who was born small for gestational age. Which of the following should the nurse include as a potential cause of this condition?
Perinatal asphyxia.
Preterm delivery.
Fetal hyperinsulinemia.
Placental insufficiency.
The Correct Answer is D
Choice A rationale
Perinatal asphyxia refers to a lack of oxygen flow to the fetus around the time of birth. This can lead to multiple organ dysfunction and neurological issues, but it is not a common cause of a newborn being small for gestational age.
Choice B rationale
Preterm delivery can result in a newborn being small for their gestational age simply because they have not had the full amount of time to grow in the womb. However, preterm babies are typically compared to other preterm babies when assessing size, not to full-term babies.
Choice C rationale
Fetal hyperinsulinemia, or an excess of insulin in the fetus, can lead to excessive growth and a larger-than-average baby size (macrosomia), not a smaller size.
Choice D rationale
Placental insufficiency, where the placenta does not work as well as it should, can limit the amount of oxygen and nutrients the fetus receives. This can restrict the baby’s growth, leading to a small size for gestational age.

Correct Answer is D
Explanation
Choice A rationale
The largest fetal diameter passing through the pelvic outlet is not what is indicated by the presenting part being at 0 station. This would be more indicative of a positive station, such as
+31.
Choice B rationale
The position of the fetal head, such as left occiput posterior, is not determined by the station of the presenting part. The station refers to the level of the presenting part in relation to the mother’s ischial spines.
Choice C rationale
The palpability of the posterior fontanel is not related to the station of the presenting part. The fontanels are soft spots on the baby’s head which allow for compression during birth and brain growth after birth.
Choice D rationale
This is the correct interpretation of the clinical finding. The presenting part is at 0 station when its lowermost portion is at the level of an imaginary line drawn between the client’s ischial spines.
Correct Answer is A
Explanation
Choice A rationale
Painless vaginal bleeding at 28 weeks of gestation can be a sign of placenta previa or placental abruption, both of which are serious conditions that require immediate attention.
Choice B rationale
While vaginal spotting after a missed period could indicate early pregnancy, it is not as immediately concerning as painless vaginal bleeding in the third trimester.
Choice C rationale
Nausea and vomiting at 14 weeks of gestation are common symptoms of early pregnancy and, while uncomfortable, are not usually a medical emergency.
Choice D rationale
A cough and fever at 38 weeks of gestation could indicate an infection, which should be evaluated. However, it is not as immediately concerning as painless vaginal bleeding in the third trimester.
