A nurse is caring for a client who is experiencing uterine atony immediately following delivery. The client fails to respond to oxytocin administration. The nurse should anticipate the use of which of the following medications?

The correct answer is choice B. Single palmar creases.

Choice A rationale:

Rust-stained urine is typically due to urate crystals and is common in newborns. It usually resolves on its own and is not a cause for concern.

Choice B rationale:

Single palmar creases can be associated with certain genetic conditions, such as Down syndrome. This finding should be reported to the provider for further evaluation.

Choice C rationale:

Subconjunctival hemorrhage is a common finding in newborns due to the pressure changes during delivery. It usually resolves without intervention and is not typically a cause for concern.

Choice D rationale:

Transient circumoral cyanosis is often seen in newborns and can occur when the baby is crying or feeding. It usually resolves on its own and is not typically a cause for concern.

Choice A rationale:
Increased fetal movement is a positive sign during pregnancy and indicates the well-being of the baby. It is not a concern and does not require reporting.

Choice B rationale:
Increased urinary output may be expected in a client receiving magnesium sulfate due to its diuretic effects. This finding is not alarming and does not require immediate reporting unless it is associated with other concerning symptoms.

Choice C rationale:
Increased muscle weakness is a potential side effect of magnesium sulfate administration. It is important to monitor the client for signs of magnesium toxicity, and increased muscle weakness should be reported promptly as it may indicate the need for adjustments in the dosage or administration of the medication.

Choice D rationale:
Increased respiratory rate is not typically associated with magnesium sulfate use and is unlikely to be a concerning finding in this context. However, it's always essential to monitor respiratory status, but it may not be specifically related to the magnesium sulfate treatment.
