A nurse is assessing a client who has preeclampsia and received a dose of calcium gluconate to treat magnesium sulfate toxicity.
Which of the following findings should the nurse identify as an indication that calcium gluconate was effective?

Choice A rationale

Preparing for a cesarean birth is not an immediate necessity unless there are complications that warrant such intervention. Cesarean births are typically reserved for situations where vaginal delivery poses a risk to the mother or the baby.

Choice B rationale

Administering IV antibiotic prophylaxis is critical in preventing potential infections during the labor process, especially given the early gestation period. This helps in safeguarding both the mother and the fetus from infections like group B streptococcus.

Choice C rationale

Obtaining a vaginal culture is generally done to check for infections such as bacterial vaginosis or sexually transmitted infections. However, it is not an immediate priority when the patient is already in active labor.

Choice D rationale

Administering metronidazole orally is used to treat bacterial infections but is not an immediate action required in this scenario. Metronidazole may not be the most suitable choice during labor as it does not provide immediate infection prevention.

Choice A rationale

A shrill cry may indicate distress but isn't specifically related to hypoglycemia in newborns.

Choice B rationale

Weak peripheral pulses are more commonly associated with circulatory or cardiac issues rather than hypoglycemia.

Choice C rationale

Yellowish skin suggests jaundice, which is due to elevated bilirubin levels, not hypoglycemia.

Choice D rationale

Hypotonia, or decreased muscle tone, can be a sign of hypoglycemia in newborns, indicating a need to check blood glucose levels.
