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?

 

A.

Prepare for a cesarean birth.

B.

Administer IV antibiotic prophylaxis.

C.

Obtain a vaginal culture.

D.

Administer metronidazole orally.

Answer and Explanation

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

Elevating the head of the client’s bed is not indicated in this situation and does not address the issue of excessive bleeding postpartum.

Choice B rationale

Administering terbutaline, a medication used to manage preterm labor, is not relevant in the context of postpartum hemorrhage and excessive bleeding.

Choice C rationale

Initiating oxygen at 2 L/min via nasal cannula may help with oxygenation but does not address the primary issue of excessive postpartum bleeding.

Choice D rationale

Initiating an infusion of oxytocin is the correct action as it helps contract the uterus and reduce postpartum bleeding, making it a crucial step in managing this situation.

Correct Answer is A

Explanation

Choice A rationale

Irregular heartbeat (palpitations or arrhythmias) can indicate a serious cardiovascular side effect of nifedipine. It requires immediate medical attention as it could compromise

maternal and fetal circulation.

Choice B rationale

Hair loss is not a known adverse effect of nifedipine and generally does not pose a significant health risk. It is more commonly associated with hormonal changes rather than

medication side effects.

Choice C rationale

Increased salivation is not a common side effect of nifedipine. Nifedipine primarily affects the cardiovascular system rather than salivary glands.

Choice D rationale

Pause is not a recognized adverse effect related to nifedipine usage. The term itself is ambiguous and not typically associated with the pharmacological profile of nifedipine.
