A 38-year-old primigravida returns to the clinic at 16 weeks gestation for an alpha-fetoprotein test.She asks a nurse, "Why do lI need this test?".Which response would be most appropriate for the nurse to make?
"This test will help us determine your baby's maturity.".
"This is a routine test for all pregnant women over thity years of age.".
This test is recommended for people with a history of infertility." "This test is used to identify fetal abnormalities.".
<p>This test is used to identify fetal abnormalities</p>
The Correct Answer is D
The correct answer is choice D: “This test is used to identify fetal abnormalities.” Alpha-fetoprotein (AFP) is a protein produced by the fetus that can be measured in the mother’s blood.
Abnormal levels of AFP may indicate a problem with the development of the baby’s brain, spine, or other organs.
This test is usually done between 15 and 20 weeks of gestation.
Choice A is wrong because AFP does not measure the baby’s maturity.
It is not related to the gestational age or the lung development of the fetus.
Choice B is wrong because AFP is not a routine test for all pregnant women over thirty years of age.
It is an optional screening test that may be offered to women who have a higher risk of having a baby with a birth defect, such as those who have a family history, a previous affected pregnancy, or certain ethnic backgrounds.
Choice C is wrong because AFP is not recommended for people with a history of infertility.
It does not assess the fertility status of the mother or the father.
It only measures the level of a fetal protein in the mother’s blood.

Correct Answer is A
Explanation
The correct answer is choice A. A patient who weighed less than 5 lb (2,268 gm) at birth is at risk for having an infant with intrauterine growth retardation (IUGR).This is because low birth weight is a possible indicator of genetic factors or placental insufficiency that can affect fetal growth.
Choice B is wrong because an ectopic pregnancy one year ago does not increase the risk of IUGR.An ectopic pregnancy is when the fertilized egg implants outside the uterus, usually in the fallopian tube.It does not affect the placental function or fetal development in a subsequent pregnancy.
Choice C is wrong because a mitral valve prolapse does not increase the risk of IUGR.
A mitral valve prolapse is when the valve between the left atrium and left ventricle of the heart does not close properly.It usually does not cause any symptoms or complications during pregnancy, unless it is associated with severe regurgitation or arrhythmias.
Choice D is wrong because the father’s age of 42 years old does not increase the risk of IUGR.The father’s age may affect the risk of chromosomal abnormalities or congenital anomalies in the fetus, but not the fetal growth.
Some of the other risk factors for IUGR include maternal smoking, alcohol, or drug use, medical conditions like anemia or lupus, infections such as rubella or syphilis, carrying twins or multiples, high blood pressure, gestational diabetes, and placenta problems.
Correct Answer is A
Explanation
The correct answer is choice A. The newborn’s nostrils flare slightly during respiration.This is a sign of respiratory distress in a newborn.
Flaring nostrils indicate that the newborn is working hard to breathe and may not be getting enough oxygen.
Choice B is wrong because the newborn’s hands and feet are blue and feel cool.This is a normal finding called acrocyanosis, which occurs due to immature peripheral circulation.
It usually resolves within 24 to 48 hours after birth.
Choice C is wrong because the newborn’s eyes move randomly when his head is turned to the side.This is a normal finding called nystagmus, which occurs due to immature eye muscles and coordination.
It usually disappears by 6 months of age.
Choice D is wrong because the newborn’s tongue thrusts forward when it is lightly touched.This is a normal finding called the extrusion reflex, which helps the newborn to suck and swallow.
It usually fades by 4 months of age.
