D. Reversal of proteinuria CORRECT ANSWER-(c) A. Magnesium sulfate is used to prevent
and treat eclamptic seizures. Magnesium sulfate is not sufficient to treat hypertension,
therefore antihypertensives must be added. Magnesium sulfate is excreted solely from the
kidneys and urine output must be preserved to prevent accumulation of the drug. Magnesium
sulfate does nothing to prevent HELLP syndrome.
