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 A
Explanation
Choice A: The client's symptoms of lightheadedness and tingling fingers indicate that she may be hyperventilating, which can occur when patternpaced breathing is too rapid. Breathing into a paper bag can help the client rebreathe some of the exhaled carbon dioxide, which can help correct the respiratory alkalosis caused by hyperventilation.
Choice B: Administering oxygen via nasal cannula may not address the underlying issue of hyperventilation. It is more appropriate to assist the client in slowing down her breathing pattern.
Choice C: Tucking the chin to the chest is not relevant to the client's symptoms of hyperventilation.
Choice D: Instructing the client to increase her respiratory rate would exacerbate the hyperventilation, leading to more symptoms of respiratory alkalosis.
Correct Answer is A
Explanation
A. Position the client on her side: Late decelerations are often associated with uteroplacental insufficiency, which may be improved by changing the maternal position to improve blood flow to the placenta.
B. Elevate the client's legs: Elevating the client's legs would not directly address the cause of late decelerations.
C. Increase the infusion rate of the IV fluid: While ensuring adequate hydration is important, it is not the priority action when late decelerations are noted.
D. Administer oxygen via a face mask: Oxygen administration may be necessary, but it is not the priority action. Positioning the client on her side to improve blood flow is the priority.
