A nurse is reviewing the laboratory results of a client with severe pre-eclampsia who is receiving magnesium sulfate.
Which finding would indicate a therapeutic level of magnesium sulfate?
Serum magnesium level of 4.5 mEq/L.
This indicates a therapeutic level of magnesium sulfate for a client with severe pre-eclampsia who is receiving magnesium sulfate. According to some sources, the effective therapeutic serum magnesium level is 1.8–3.0 mmol/L, which corresponds to 4.2–7 mg/dL or 3.5–7 mEq/L.
Serum calcium level of 8.5 mg/dL is within the normal range and does not indicate the effect of magnesium sulfate.
Serum creatinine level of 1.2 mg/dL is within the normal range and does not indicate the effect of magnesium sulfate.
Serum potassium level of 3.5 mEq/L is at the lower end of the normal range and does not indicate the effect of magnesium sulfate.
This indicates a therapeutic level of magnesium sulfate for a client with severe pre-eclampsia who is receiving magnesium sulfate. According to some sources, the effective therapeutic serum magnesium level is 1.8–3.0 mmol/L, which corresponds to 4.2–7 mg/dL or 3.5–7 mEq/L.
Choice B is wrong because serum calcium level of 8.5 mg/dL is within the normal range and does not indicate the effect of magnesium sulfate.
Choice C is wrong because serum creatinine level of 1.2 mg/dL is within the normal range and does not indicate the effect of magnesium sulfate.
Choice D is wrong because serum potassium level of 3.5 mEq/L is at the lower end of the normal range and does not indicate the effect of magnesium sulfate.
