A nurse is monitoring a client with severe pre-eclampsia who is receiving magnesium sulfate intravenously.
Which of the following signs indicates magnesium toxicity and requires immediate intervention?
Loss of reflexes
Headache
Nausea

• Drowsiness or confusion
• Low blood pressure
• Slow heart rate

Correct Answer is A
Explanation
Two or more accelerations of at least 15 beats/min above baseline lasting for at least 15 seconds in a 20-minute period.This indicates a reactive test, which means that the fetus is well oxygenated and not in distress.
Choice B is wrong because no accelerations or decelerations in a 20-minute period indicate a non-reactive test, which may suggest fetal hypoxia or acidosis.
Choice C is wrong because one acceleration of at least 10 beats/min above baseline lasting for at least 10 seconds in a 20-minute period is the criterion for a reactive test for gestational age less than 32 weeks, not 34 weeks.
Choice D is wrong because variable decelerations with normal variability in a 20-minute period indicate cord compression or fetal head compression, not a reactive test.
Correct Answer is C
Explanation
To accelerate fetal lung maturity.Corticosteroids are given to pregnant women with severe pre-eclampsia who are at risk of preterm delivery to help the development of the fetus’s lungs and reduce the risk of respiratory distress syndrome.
This can improve the survival and health outcomes of the newborn.
Choice A is wrong because corticosteroids do not reduce inflammation in pre-eclampsia.They are used for other inflammatory conditions such as asthma or arthritis.
Choice B is wrong because corticosteroids do not prevent infection in pre-eclampsia.They can actually increase the risk of infection by suppressing the immune system.
Choice D is wrong because corticosteroids do not increase platelet count in pre-eclampsia.They can actually decrease the platelet count by causing thrombocytopenia.
