A nurse is reinforcing teaching with a client who is 15 weeks pregnant about to undergo amniocentesis. This test can identify which traits or problems? Select all that apply.
Rh incompatibility.
Neural tube defects.
Fetal gender.
Cephalopelvic disproportion.
Chromosomal defects.
Correct Answer : B,C,E
Choice A:
Rh incompatibility is not directly identified through amniocentesis. Instead, it's typically assessed through blood tests that determine a woman's Rh factor and screen for Rh antibodies.
However, amniocentesis can provide information that might be relevant to Rh incompatibility, such as the fetal Rh type. If the mother is Rh-negative and the fetus is Rh-positive, there's a risk of Rh incompatibility.
Choice B:
Amniocentesis can detect neural tube defects (NTDs) like spina bifida and anencephaly.
It does this by measuring the levels of alpha-fetoprotein (AFP) in the amniotic fluid. AFP is a protein produced by the fetal liver, and elevated levels in the amniotic fluid can indicate an NTD.
Choice C:
Amniocentesis can accurately determine the fetal gender by examining the sex chromosomes present in the cells of the amniotic fluid.
Choice D:
Cephalopelvic disproportion (CPD) is a condition where the baby's head is too large to fit through the mother's pelvis. It's not diagnosed through amniocentesis.
CPD is usually suspected based on clinical findings like a slow progression of labor or a high fetal station, and it might be confirmed with imaging techniques like X-ray or ultrasound.
Choice E:
Amniocentesis is a valuable tool for diagnosing chromosomal defects, such as Down syndrome, Trisomy 18, and Trisomy 13. It does this by analyzing the chromosomes of the fetal cells present in the amniotic fluid.

Correct Answer is D
Explanation
The correct answer is Choice D.
Choice A rationale: The client's age, being 20 years old, is not a contraindication to the use of a diaphragm. Diaphragms can be used by individuals of reproductive age, provided there are no other contraindications.
Choice B rationale: Having a vaginal birth 6 months ago is not a contraindication to using a diaphragm. The diaphragm's fit may need adjustment, but it can still be used safely postpartum.
Choice C rationale: Smoking cigarettes is a risk factor for several health conditions but is not a specific contraindication for the use of a diaphragm. However, smoking cessation should be encouraged for overall health benefits.
Choice D rationale: Having more than one sex partner increases the risk of sexually transmitted infections (STIs). Diaphragms do not protect against STIs, making it important to use condoms in conjunction with the diaphragm for clients with multiple sex partners.
