A nurse is assessing a client who has placenta previa and is receiving fetal monitoring.Which of the following clinical findings should the nurse expect?
Variable decelerations.
Painless vaginal bleeding.
Rigid abdomen.
Uterine tachysystole.
The Correct Answer is B
Choice A rationale
Variable decelerations are associated with umbilical cord compression, not placenta previa. In placenta previa, the placenta covers the cervical os, but it does not typically cause variable decelerations on fetal monitoring.
Choice B rationale
Painless vaginal bleeding is a hallmark sign of placenta previa. This occurs because the placenta is located near or over the cervical os, leading to bleeding when the cervix dilates or effaces.
Choice C rationale
A rigid abdomen is more indicative of placental abruption, where the placenta detaches prematurely from the uterine wall, causing pain and a tense abdomen, not typically seen in placenta previa.
Choice D rationale
Uterine tachysystole is characterized by excessive uterine contractions and is not a clinical finding related to placenta previa. Tachysystole often results from excessive oxytocin use or other uterine stimulants.

Correct Answer is B
Explanation
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. .

Explanation
- Administration of IV fluids: This is anticipated as it ensures the client remains well-hydrated, which is important for both maternal and fetal health.
- Continuous monitoring of FHR: This is anticipated to monitor the fetal well-being and ensure there are no signs of fetal distress.
- Abdominal ultrasound: This is anticipated to assess fetal growth, amniotic fluid levels, and placental positioning.
- Digital cervical exam to assess dilation and effacement: This is contraindicated because frequent cervical exams can increase the risk of infection and may cause unnecessary discomfort, especially if there are no signs of labor.
- Laboratory testing: CBC, Blood Type & Rh, Coagulation Studies: These tests are anticipated to provide important information about the client's blood count, blood type, Rh status, and coagulation parameters, which are crucial for managing potential complications.
- Placement of an internal fetal spiral electrode: This is contraindicated as it is an invasive procedure that carries risks, and it is unnecessary given that the FHR is within normal limits with external monitoring.
- Administration of betamethasone: This is anticipated as betamethasone is often given to promote fetal lung maturity in cases where there is a risk of preterm birth.
