A nurse is developing an educational program about hemolytic disease in newborns for a group of newly licensed nurses. Which of the following genetic information should the nurse include in the program as a cause of hemolytic disease?

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:

This manifestation, urine output of 20 mL/hr, is an adverse reaction to magnesium sulfate administration. Magnesium sulfate can lead to decreased urine output, and it is essential for the nurse to monitor the client's urinary output closely. Low urine output may indicate decreased kidney function, which can be a sign of magnesium toxicity.

Choice B rationale:

Hypertension is expected in a client with preeclampsia, and magnesium sulfate is used to help manage and prevent seizures in these cases. While it is essential to monitor and manage hypertension during pregnancy, it is not considered an adverse reaction to magnesium sulfate.

Choice C rationale:

Hyperglycemia is not a common adverse reaction to magnesium sulfate. Magnesium sulfate may cause central nervous system depression, muscle weakness, and respiratory depression, but it does not typically cause hyperglycemia.

Choice D rationale:

A respiratory rate of 16/min is within the normal range for an adult and is not indicative of an adverse reaction to magnesium sulfate. Magnesium sulfate can cause respiratory depression at higher doses, but a respiratory rate of 16/min does not raise immediate concerns.
