A nurse is assisting with the care of a client who received magnesium sulfate to treat preterm labor. The nurse should monitor the client for which of the following findings as an indication of magnesium sulfate toxicity?
Nausea.
Facial flushing.
Urine output 40 mL/hr.
Respiratory rate 10/min.
The Correct Answer is D
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
"You will be tested again for GBS at about 36 weeks of gestation.”. This is correct because retesting for GBS at 35-37 weeks of gestation is standard practice to identify colonization status before delivery, which helps in planning intrapartum antibiotic prophylaxis.
Choice B rationale
"If you test positive for GBS, the provider will need to perform a cesarean birth.”. This is incorrect because GBS colonization is not an indication for cesarean delivery. The primary intervention is antibiotic administration during labor to prevent neonatal infection.
Choice C rationale
"You will take an antibiotic during the last 2 weeks of pregnancy to avoid transferring GBS to your baby.”. This is incorrect because antibiotics are given intrapartum (during labor) to prevent GBS transmission, not during the last weeks of pregnancy.
Choice D rationale
"This infection can cause your baby to experience hearing loss at birth.”. This is incorrect because GBS infection primarily causes sepsis, pneumonia, and meningitis in neonates, not hearing loss.
Correct Answer is A
Explanation
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.
