A nurse is caring for a newborn whose mother is positive for the hepatitis B surface antigen.Which of the following should the infant receive?

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.

Choice A rationale

Ambivalent feelings are common in early pregnancy due to hormonal changes and the significant life adjustments that accompany pregnancy. It is normal for pregnant women to experience mixed emotions as they adapt to the reality of impending parenthood.

Choice B rationale

Suggesting the client speak to her mother about these feelings may not be appropriate as it could dismiss the client's current feelings and needs. While family support is valuable, the nurse should first address the client's concerns directly.

Choice C rationale

Referring the client to a counselor may be necessary in some cases, but it is essential to first normalize the client's feelings. It helps in providing immediate reassurance and understanding before suggesting further intervention.

Choice D rationale

Telling the client "Don't worry, you will be fine once the baby is born" is dismissive and minimizes her current concerns. It is important to validate her feelings and provide supportive responses to help her cope with her emotions.
