A nurse is caring for a client who is in labor and has a diagnosis of group B streptococcus B- hemolytic infection. Which of the following medications should the nurse plan to administer?

Choice A rationale:

When late decelerations are noted in the fetal heart rate (FHR) tracing, it indicates that the fetal oxygen supply may be compromised. The nurse should first change the client's position, such as moving her to the left lateral position or a hands-and-knees position, to improve uteroplacental blood flow and relieve pressure on the vena cava.

Choice B rationale:

Palpating the uterus to assess for tachysystole is not the priority action when late decelerations are observed. Tachysystole refers to excessively frequent uterine contractions and may contribute to fetal distress, but the immediate concern is addressing the decelerations.

Choice C rationale:

Increasing the client's IV infusion rate may not address the underlying cause of late decelerations. While maintaining hydration is important, it's not the first action to take in this situation.

Choice D rationale:

Administering oxygen at 10 L/min via a non-rebreather mask may be beneficial for the client and fetus, but it is not the first action to take. The nurse should address the position change first to improve oxygenation through better blood flow before considering supplemental oxygen.

Choice A rationale:

Gravida refers to the number of times a woman has been pregnant, and Para indicates the number of pregnancies that have reached viability (at least 20 weeks) Since the client has

been pregnant for the fourth time and delivered two full-term newborns (reached viability), she is gravida 4, and since she had one spontaneous abortion (miscarriage) at 10 weeks of gestation, she is para 2 (two pregnancies reached viability)

Choice B rationale:

This choice would be incorrect because it indicates that the client has had three pregnancies reaching viability, but she has only had two full-term newborns and one miscarriage.

Choice C rationale:

This is the correct choice, as explained above. Choice D rationale:

This choice would be incorrect because it indicates that the client has had four pregnancies reaching viability, but she has only had two full-term newborns and one miscarriage.
