[2025-10-02T00:18:51.215082] [PI reasoning] **Considering MgSO4 loading doses**

I’m looking into a question about preparing a loading dose of magnesium sulfate (MgSO4) for IV use, possibly related to obstetrics nursing or anesthesia. In managing preeclampsia or eclampsia, the Pritchard regimen involves giving a 4 g loading dose of MgSO4 IV as a 20% solution in 200 mL, slowly over 5-10 minutes. There’s also the Zuspan regimen, which consists of a single 4 g IV loading dose over 5 minutes, derived from a 10% solution. I’ll need to clarify further details regarding concentrations.
