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: 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.
Correct Answer is A
Explanation
Choice A rationale: During phototherapy, it is essential to maintain adequate hydration and nutrition for the newborn. Encouraging frequent breastfeeding helps provide the baby with essential nutrients and fluids, which can be lost due to increased stooling caused by phototherapy.
Choice B rationale: The use of lotion on the newborn's skin during phototherapy is not recommended, as it may interfere with the effectiveness of the light therapy. The skin needs to be exposed to the light for the treatment to work.
Choice C rationale: Monitoring the newborn's blood glucose level is not directly related to phototherapy. Blood glucose monitoring may be necessary for specific medical reasons, but it is not a standard intervention during phototherapy.
Choice D rationale: During phototherapy, the newborn is usually placed in a supine (face-up) position to ensure maximum exposure of the skin to the phototherapy lights. The prone position is not recommended during phototherapy as it may reduce the effectiveness of the treatment.
