Final answer:
Therapeutic hypermagnesemia level in preeclampsia has not been specifically determined. Normal magnesium levels in the blood range from 1.8 to 2.4 mg/dL (0.75 to 0.99 mmol/L). Magnesium sulfate may be administered in preeclampsia cases to prevent seizures.
Step-by-step explanation:
Therapeutic hypermagnesemia level in preeclampsia has not been specifically determined. However, low levels of magnesium are reported in normal and abnormal pregnancy. Normal levels of magnesium in the blood range from 1.8 to 2.4 mg/dL (0.75 to 0.99 mmol/L). In preeclampsia, magnesium sulfate may be administered as a treatment to prevent seizures in severe cases, but it is important to closely monitor magnesium levels to avoid hypermagnesemia.
