A nurse is admitting a client who is at 39 weeks of gestation and in active labor. The client reports being positive for group B streptococcus (GBS) when screened at 36 weeks of gestation. Which of the following actions should the nurse expect to take?
Prepare for a cesarean birth.
Administer IV antibiotic prophylaxis.
Obtain a vaginal culture.
Administer metronidazole orally.
The Correct Answer is B
Choice A rationale
Cesarean birth is not necessarily required for GBS-positive clients as long as IV antibiotic prophylaxis is administered during labor to prevent transmission to the newborn.
Choice B rationale
IV antibiotic prophylaxis, typically with penicillin or ampicillin, is given to GBS-positive clients during labor to prevent neonatal GBS infection.
Choice C rationale
Obtaining a vaginal culture at 39 weeks of gestation is not necessary if the client was already screened and found positive for GBS at 36 weeks.
Choice D rationale
Metronidazole is used to treat bacterial vaginosis or trichomoniasis, not GBS infection; thus, it is not appropriate for this scenario. .

Correct Answer is D
Explanation
Choice A rationale
Transient circumoral cyanosis is common in newborns, especially when crying or feeding, and usually resolves on its own without intervention.
Choice B rationale
Transient strabismus, or the temporary crossing of the eyes, is normal in newborns due to underdeveloped eye muscles and usually resolves as the infant grows.
Choice C rationale
Caput succedaneum is the swelling of the scalp caused by pressure during delivery. It is usually benign and resolves within a few days without treatment.
Choice D rationale
Generalized petechiae, or small red or purple spots on the skin, can indicate a serious underlying condition such as a clotting disorder or infection and requires immediate medical evaluation.
Correct Answer is C
Explanation
Choice A rationale
Cooling the newborn’s heel would constrict blood vessels and make it more difficult to obtain a blood sample. Warming the heel is the preferred method to increase blood flow.
Choice B rationale
Puncturing the center of the newborn’s heel is not recommended as it could cause more pain and potential injury to the bone. The puncture should be done on the outer edges of the heel.
Choice C rationale
Cleansing the puncture site with alcohol gauze is essential to reduce the risk of infection and ensure that the sample is not contaminated.
Choice D rationale
Administering vitamin K before each blood draw is unnecessary. Vitamin K is typically given as a one-time dose to prevent bleeding issues, not related to blood draw procedures.
