A nurse is caring for a client who is at 30 weeks of gestation.
The nurse should plan to immunize the client with which of the following vaccines? (Select all that apply)

Choice A rationale

For a client with moderate abruptio placenta, which involves premature separation of the placenta from the uterine wall, the primary concern is fetal well-being due to impaired oxygen and nutrient exchange, and maternal hemorrhage. Therefore, continuous monitoring of fetal heart rate (FHR) tracings is a priority to assess for signs of fetal compromise (e.g., late decelerations, bradycardia, nonreassuring patterns) and determine the urgency for delivery.

Choice B rationale

Ferning is a microscopic test where a sample of vaginal fluid is allowed to dry on a slide; the characteristic fern pattern indicates the presence of amniotic fluid. This test is used to confirm rupture of membranes. This is not the immediate priority intervention for abruptio placenta, which is focused on managing hemorrhage and fetal distress, and a vaginal examination may be contraindicated if bleeding is severe.

Choice C rationale

Assessing for cervical dilation requires a vaginal examination. While important for determining labor progression, a vaginal examination is often contraindicated in the setting of unexplained vaginal bleeding until a placenta previa is ruled out by ultrasound, as a digital exam could potentially cause a severe hemorrhage if the placenta is covering the cervix. The FHR is a higher priority.

Choice D rationale

Administering oxytocin is a uterotonic agent used to induce or augment labor. In moderate to severe abruptio placenta, if the client is not in active labor or the bleeding is significant, emergency cesarean delivery might be required. Furthermore, the goal is often to deliver the fetus as quickly and safely as possible; oxytocin is not the initial management and could increase uterine tone, potentially worsening the abruption if not used carefully under close monitoring.

Choice A rationale: The cervix being closed and thick at 42 weeks gestation is unfavorable and increases the risk for labor complications. At this stage, the cervix should ideally be effaced and dilated to allow for labor progression. A closed, thick cervix indicates poor readiness for labor, which may necessitate induction with cervical ripening agents. Failure of the cervix to ripen increases the risk of prolonged labor, failed induction, and cesarean delivery, making this a significant complication risk factor.

Choice B rationale: Being at 42 weeks gestation is post-term, which increases the risk for labor complications. Post-term pregnancy is associated with oligohydramnios, macrosomia, meconium aspiration, and placental insufficiency. These conditions can lead to fetal distress, shoulder dystocia, and increased rates of operative delivery. Therefore, advanced gestational age beyond 41 weeks is a recognized risk factor for complications, requiring close monitoring and often induction of labor to reduce maternal and neonatal morbidity.

Choice C rationale: A fetal heart rate of 150/min is within the normal baseline range of 110 to 160 beats per minute. This indicates adequate fetal oxygenation and no evidence of tachycardia or bradycardia. Since the FHR is normal and reassuring, it does not increase the risk for labor complications. Continuous monitoring is still important, but this specific finding is not a complication risk factor.

Choice D rationale: Clear to white mucus-like vaginal discharge is a normal physiologic finding in pregnancy, known as leukorrhea. It results from increased estrogen and cervical gland activity. This type of discharge is not associated with infection, rupture of membranes, or preterm labor. Since it is expected and benign, it does not increase the risk for labor complications. Only abnormal discharges such as foul-smelling, green, or bloody secretions would be concerning.

Choice E rationale: Vertex presentation, specifically left occiput anterior, is the most favorable fetal position for vaginal delivery. It allows for optimal alignment of the fetal head with the maternal pelvis, facilitating descent and rotation during labor. Malpresentations such as breech or transverse would increase the risk for complications, but vertex LOA is ideal. Therefore, this finding is favorable and does not increase the risk for labor complications.
