The nurse instructs a pregnant client that the purpose of an amniocentesis at 36 weeks gestation is for:
Identifying the sex of the fetus.
Detection of metabolic disorders.
Determining fetal lung maturity.
Identification of abnormal fetal cells.
The Correct Answer is C
Choice A rationale
The sex of the fetus can be determined earlier through ultrasound or blood tests, making amniocentesis at 36 weeks unnecessary for this purpose.
Choice B rationale
Detection of metabolic disorders can also be done earlier in the pregnancy through other tests. Amniocentesis at 36 weeks is not typically used for this purpose.
Choice C rationale
Determining fetal lung maturity is a primary reason for performing an amniocentesis at 36 weeks gestation. This test assesses whether the fetus's lungs are developed enough for the baby to breathe independently after birth.
Choice D rationale
Identification of abnormal fetal cells can be done earlier in pregnancy through amniocentesis or other genetic tests. It is not the primary reason for amniocentesis at 36 weeks.
