Clinical Features ( 16 Questions)
A client who is 36 weeks pregnant is admitted to the hospital with a diagnosis of eclampsia.
She has a history of chronic hypertension and gestational diabetes.
The nurse anticipates that the client will receive which of the following medications to prevent seizures?
Hydralazine is a blood pressure medication that can lower blood pressure in people with preeclampsia or eclampsia, but it does not prevent seizures.
Nifedipine is another blood pressure medication that can lower blood pressure in people with preeclampsia or eclampsia, but it does not prevent seizures.
Magnesium sulfate is the drug of choice to prevent and treat seizures in people with severe preeclampsia and eclampsia. It is an anticonvulsant medication that reduces the risk of eclampsia by 50%.
Normal ranges for blood pressure are below 140/90 mm Hg, for proteinuria are below 300 mg/24 hours, for platelet count are 150,000 to 450,000 per microliter, for liver enzymes are 7 to 56 units per liter for alanine aminotransferase (ALT) and 10 to 40 units per liter for aspartate aminotransferase (AST), and for magnesium levels are 1.5 to 2.5 mEq/L.
Diazepam is an anticonvulsant medication that was previously used to treat eclamptic seizures, but it has been replaced by magnesium sulfate as the preferred drug due to its better safety and efficacy. Diazepam can also cause sedation and respiratory depression in the mother and the fetus.
