A nurse is reinforcing teaching with a client who tested positive for group B streptococcus β-hemolytic (GBS) during a prior pregnancy and is at 30 weeks of gestation. Which of the following statements should the nurse make?
"You will be tested again for GBS at about 36 weeks of gestation.”.
"If you test positive for GBS, the provider will need to perform a cesarean birth.”.
"You will take an antibiotic during the last 2 weeks of pregnancy to avoid transferring GBS to your baby.”.
"This infection can cause your baby to experience hearing loss at birth.”.
The Correct Answer is A
Choice A rationale
Testing for GBS at around 36 weeks of gestation is standard practice to identify carriers and prevent neonatal GBS infections through intrapartum antibiotic prophylaxis if necessary.
Choice B rationale
Cesarean birth is not indicated solely based on a positive GBS status. The primary intervention is intrapartum antibiotic prophylaxis to reduce the risk of neonatal infection.
Choice C rationale
Routine antibiotic administration during the last weeks of pregnancy is not standard practice; antibiotics are given during labor if GBS is present to prevent transmission to the baby.
Choice D rationale
GBS infection does not cause hearing loss in newborns. The primary concern is neonatal sepsis, pneumonia, or meningitis, not hearing loss.

Correct Answer is D
Explanation
Choice A rationale
Nausea can be a side effect of magnesium sulfate, but it is not a specific indication of toxicity. Other symptoms are more directly indicative of magnesium sulfate overdose.
Choice B rationale
Facial flushing is a common side effect of magnesium sulfate but is not a sign of toxicity. It typically occurs at therapeutic levels and is not a reliable indicator of overdose.
Choice C rationale
Urine output of 40 mL/hr is within normal limits for an adult and does not indicate magnesium sulfate toxicity. However, significantly decreased urine output could be concerning.
Choice D rationale
Respiratory rate of 10/min is a critical sign of magnesium sulfate toxicity. Magnesium sulfate can cause respiratory depression, and a rate of 10 breaths per minute or less indicates that the patient may be experiencing toxic effects, necessitating immediate medical intervention.
Correct Answer is A
Explanation
Choice A rationale
Amniocentesis is used to detect fetal genetic abnormalities, such as Down syndrome, by analyzing the amniotic fluid for genetic markers.
Choice B rationale
An empty bladder is required for the test only in late pregnancy to prevent bladder injury; however, in early pregnancy, a full bladder may be required to better visualize the uterus and amniotic fluid.
Choice C rationale
An x-ray is not typically used during the needle placement for amniocentesis. Ultrasound is the preferred method to guide the needle to avoid harm to the fetus and mother.
Choice D rationale
The test does not determine the volume of amniotic fluid; it is used primarily for genetic analysis, assessing fetal lung maturity, and diagnosing certain fetal infections.
