A nurse is providing teaching about the expected effects of magnesium sulfate to a client who is at 28 weeks of gestation and has preeclampsia.
Which of the following responses by the nurse is appropriate?
"This medication increases cardiac output.”.
"This medication prevents seizures.”.
"This medication stabilizes the fetal heart rate.”.
"This medication improves tissue perfusion.”.
The Correct Answer is B
Choice A rationale:
Magnesium sulfate does not increase cardiac output. It is a central nervous system depressant and muscle relaxant.
Choice B rationale:
Magnesium sulfate is given to clients with preeclampsia to prevent seizures, which can be a complication of this condition.
Choice C rationale:
Magnesium sulfate does not directly stabilize the fetal heart rate. Its primary use in preeclampsia is seizure prevention.
Choice D rationale:
While magnesium sulfate can cause vasodilation, which could improve tissue perfusion, its primary use in preeclampsia is to prevent seizures.

Correct Answer is A
Explanation
The correct answer is choice A. Single palmar creases.
Choice A rationale: Single palmar creases (also known as simian creases) can be associated with certain genetic conditions, such as Down syndrome. The presence of this finding in a newborn should prompt further investigation and reporting to the healthcare provider for additional assessment and possible genetic testing.
Choice B rationale: Rust-stained urine in a newborn is typically caused by uric acid crystals, which are common and not considered abnormal during the first few days of life. This condition usually resolves without intervention, and it does not require reporting to the provider unless it persists or is accompanied by other symptoms.
Choice C rationale: Transient circumoral cyanosis is a common finding in newborns, especially when crying or feeding. It usually resolves on its own and is not considered an alarming sign unless it persists or is associated with central cyanosis or other signs of respiratory distress.
Choice D rationale: Subconjunctival hemorrhage is a common finding in newborns, usually resulting from the pressure changes during delivery. It typically resolves on its own within a few weeks and does not require reporting to the provider unless there are signs of other underlying conditions.
Correct Answer is A
Explanation
Choice A rationale:
The nurse should use fingers to exert upward pressure on the presenting part to relieve cord compression, which is the immediate priority in this emergency situation.
Choice B rationale:
Administering a tocolytic medication is not the immediate priority. It may be done later to inhibit uterine contractions.
Choice C rationale:
Applying oxygen to the client is important, but it’s not the first action. The nurse needs to relieve cord compression first.
Choice D rationale:
Wrapping the cord in a sterile towel and moistening with warm sterile normal saline is important, but it’s not the first action. The nurse needs to relieve cord compression first.
