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.

Answer and Explanation

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.

Correct Answer is A

Explanation

Choice A rationale

At 9 weeks gestation, the primary purpose of an ultrasound is to confirm the presence of a fetal heartbeat, which indicates a viable pregnancy.

Choice B rationale

Chromosomal defects are typically assessed using different tests, such as chorionic villus sampling or amniocentesis, rather than an ultrasound at this early stage.

Choice C rationale

Fetal lung maturity cannot be assessed at 9 weeks gestation because the lungs are not yet developed. This assessment is usually done later in pregnancy if preterm delivery is anticipated.

Choice D rationale

The position of the fetus in utero is not a concern at this early stage of pregnancy. Fetal positioning becomes relevant later in pregnancy, closer to delivery.

A. The fourth week of gestation. B. The sixth week of gestation. C. The seventh week of gestation. D. The twelfth week of gestation.

Correct Answer is D

Explanation

Choice A rationale

The fetal heartbeat can be heard with a Doppler at the fourth week of gestation is incorrect. At this early stage, the embryonic heart has only just begun to form, and its activity cannot be detected by Doppler.

Choice B rationale

The fetal heartbeat can be heard with a Doppler at the sixth week of gestation is incorrect. Although the heart begins to beat around this time, it is usually too faint to be detected by Doppler.

Choice C rationale

The fetal heartbeat can be heard with a Doppler at the seventh week of gestation is incorrect. It remains challenging to detect the fetal heartbeat this early with standard Doppler equipment.

Choice D rationale

The fetal heartbeat can be heard with a Doppler at the twelfth week of gestation is correct. By the end of the first trimester, the fetal heart is sufficiently developed and strong enough to be detected using Doppler ultrasound, allowing healthcare providers to monitor fetal well-being.
