A nurse is teaching a client who is at 18 weeks of gestation and is to undergo an amniocentesis. The nurse should explain that the purpose of this test is to identify which of the following? (Select all that apply.)
"Gender of the fetus"
"Anomalies in fetal chromosomes"
"Rh incompatibility"
"Cephalopelvic disproportion"
"Neural tube defects"
Correct Answer : B,E
Choice A: Amniocentesis is not primarily performed to determine the gender of the fetus. The main indication for this procedure is to detect genetic abnormalities or chromosomal disorders.
Choice B: The primary purpose of an amniocentesis is to detect chromosomal abnormalities such as Down syndrome (trisomy 21), trisomy 18, and trisomy 13, among others.
Choice C: Rh incompatibility is assessed through blood tests, not amniocentesis. It involves determining the Rh factor of the mother's blood and monitoring for potential Rh sensitization.
Choice D: Cephalopelvic disproportion refers to a situation where the baby's head is too large or the mother's pelvis is too small to allow for a vaginal delivery. It is not related to amniocentesis.
Choice E: While detecting neural tube defects can be done through amniocentesis, it is not the primary indication for the procedure. Neural tube defects can also be screened for through blood tests and ultrasound examinations. Amniocentesis is more commonly used for chromosomal analysis.

Correct Answer is C
Explanation
Choice A: While an upright position is generally beneficial during labor to improve uterine contractions and fetal positioning, it is not the priority in this situation of hypotension.
Choice B: Preparing for a cesarean birth is not indicated solely based on the blood pressure reading. Cesarean birth should be considered based on the overall assessment and clinical condition of the client and baby.
Choice C: The client's blood pressure reading of 82/52 mm Hg indicates hypotension. In this situation, the nurse should assist the client in turning onto her side to relieve pressure on the vena cava and improve blood flow to the placenta and the baby. Lying supine can compress the vena cava, leading to decreased venous return and reduced cardiac output, which may negatively affect fetal oxygenation and maternal wellbeing.
Choice D: Preparing for an immediate vaginal delivery is not the priority at this moment. The nurse should first address the hypotension and improve maternal blood flow before proceeding with delivery.
Correct Answer is A
Explanation
A: Engaging in moderate physical activity during pregnancy, such as jogging, is generally safe and beneficial for pregnant women who have uncomplicated pregnancies. Staying hydrated, avoiding excessive exertion, and preventing overheating are important considerations during exercise.
B: The use of saunas and hot tubs during pregnancy is generally not recommended at any trimester, as they can cause hyperthermia and pose risks to the developing fetus.
C: Limiting exercise to only stretching on a mat is not appropriate during pregnancy. Regular physical activity is generally encouraged, provided there are no specific contraindications or complications.
D: Completely avoiding exercise during pregnancy is not recommended, as moderate and appropriate physical activity can have various benefits for both the mother and the baby.
