A nurse is reinforcing teaching with a client who is at 15 weeks of gestation and is about to undergo an amniocentesis. The nurse should reinforce that this test can identify which of the following traits or problems? (Select all that apply.)
Cephalopelvic disproportion
Neural tube defects
Rh incompatibility
Fetal gender
Chromosome defects
Correct Answer : B,C,D,E
Choice A rationale: Cephalopelvic disproportion is a condition where the baby's head is too large or the mother's pelvis is too small for a vaginal delivery. Amniocentesis does not provide information about this condition.
Choice B rationale: Amniocentesis can be used to detect neural tube defects such as spina bifida and anencephaly.
Choice C rationale: Rh incompatibility occurs when the mother is Rh-negative, and the fetus is Rh-positive. This can lead to hemolytic disease of the newborn (HDN) if untreated. While Rh incompatibility can be detected through blood tests (maternal blood), amniocentesis is typically not used to diagnose this condition.
Choice D rationale: Amniocentesis can be used to determine the fetal gender by analyzing the DNA in the amniotic fluid. This is not the primary purpose of amniocentesis, but it can certainly identify the gender, especially in cases where this information is needed for medical reasons, such as gender-linked genetic disorders.
Choice E rationale: Amniocentesis is commonly used to screen for chromosomal abnormalities such as Down syndrome (trisomy 21) and other genetic conditions.

Correct Answer is C
Explanation
Choice A rationale: Kernicterus is a severe form of jaundice that can result from untreated hyperbilirubinemia in a newborn. The indirect Coombs test does not assess the risk of kernicterus specifically.
Choice B rationale: The indirect Coombs test detects Rh-negative antibodies in the mother's blood, not Rh-positive antibodies.
Choice C rationale: The indirect Coombs test, also known as the indirect antiglobulin test (IAT), is performed on a pregnant woman to detect the presence of Rh-negative antibodies in her blood. If the mother is Rh-negative and has been sensitized to Rh-positive blood, these antibodies can cross the placenta and attack the red blood cells of an Rh-positive fetus, potentially causing hemolytic disease of the newborn (HDN) or erythroblastosis fetalis.
Choice D rationale: The direct Coombs test (direct antiglobulin test) is used to detect the presence of maternal antibodies that have already been attached to the newborn's red blood cells. The indirect Coombs test is used to identify the presence of these antibodies in the mother's blood before they have attached to the newborn's red blood cells.
Correct Answer is D
Explanation
Choice A rationale: Ventricular septal defect (VSD) is a congenital heart defect and is not directly related to respiratory distress syndrome or respiratory acidosis.
Choice B rationale: Cesarean birth, while it can have other implications, is not a direct risk factor for respiratory distress syndrome or respiratory acidosis. The mode of delivery does not directly impact the newborn's respiratory function.
Choice C rationale: While being small for gestational age can be associated with certain health challenges, it is not a direct risk factor for respiratory distress syndrome or respiratory acidosis. The baby's size does not determine its respiratory status.
Choice D rationale: Maternal history of asthma is a risk factor that can predispose the newborn to respiratory difficulties, including respiratory distress syndrome (RDS) and respiratory acidosis. Infants born to mothers with asthma may have a higher likelihood of developing respiratory problems due to potential genetic factors and exposure to environmental triggers during pregnancy.
