Correct Answer is ["A","B","C","E"]

The correct answer is choice A, B, C and E.The nurse should monitor the client’s deep tendon reflexes hourly because magnesium sulfate can cause neuromuscular blockade and decreased reflexes.The nurse should keep calcium gluconate readily available because it is the antidote for magnesium toxicity.The nurse should maintain a urine output of at least 40 mL/hr because magnesium is excreted by the kidneys and low urine output can indicate renal impairment or fluid overload.The nurse should check the client’s blood pressure every 15 minutes because magnesium sulfate can cause hypotension and preeclampsia can cause hypertension.
Choice D is wrong because the medication should not be infused via a peripheral IV line, but rather through a central line or a large-bore IV catheter to prevent tissue damage.
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.
