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.

Correct Answer is A
Explanation
Choice A rationale
Rh(D) immunoglobulin prevents the formation of Rh antibodies in Rh-negative mothers. This is crucial to prevent Rh sensitization, which can lead to hemolytic disease of the newborn in current and future pregnancies.
Choice B rationale
Rh(D) immunoglobulin does not prevent the formation of Rh antibodies in newborns who are Rh positive. Instead, it works by preventing the mother's immune system from recognizing Rh-positive fetal cells.
Choice C rationale
Rh(D) immunoglobulin does not destroy Rh antibodies in Rh-negative mothers. Its purpose is to prevent the formation of these antibodies in the first place.
Choice D rationale
Rh(D) immunoglobulin does not destroy Rh antibodies in newborns who are Rh positive. The newborn's immune system is not targeted by this immunoglobulin.

Explanation
Choice A Rationale
Administer azithromycin 1 g PO one time: Anticipated. Azithromycin is commonly used to treat chlamydia infections during pregnancy and is considered safe.
Choice B Rationale
Administer ibuprofen 600 mg PO twice a day for pain: Contraindicated. Ibuprofen is generally avoided during pregnancy, especially in the third trimester, due to risks such as premature closure of the fetal ductus arteriosus.
Choice C Rationale
Notify all sexual partners within prior 30 days of the need for STI screening: Anticipated. Notification of sexual partners for STI screening is a standard public health practice to prevent the spread of infections.
Choice D Rationale
Administer ceftriaxone 250 mg IM now: Anticipated. Ceftriaxone is often used to treat gonorrhea infections during pregnancy and is considered safe for both mother and fetus.
Choice E Rationale
Repeat STI screening at next prenatal visit in 1 month: Anticipated. Repeating STI screening can help ensure that any new or untreated infections are identified and managed appropriately.
Choice F Rationale
Notify the appropriate public health agency: Anticipated. Reporting certain STIs to public health agencies is required by law to help track and control the spread of infections.
