A laboring client with preeclampsia is prescribed magnesium sulfate 2 g/hour I.V. piggyback. The pharmacy sends the I.V. to the unit labeled magnesium sulfate 20 g/500 mL normal saline. To deliver the correct dose, the nurse should set the pump to deliver how many milliliters per hour?
Correct answer
50
Rationale
To calculate the correct dose: (2 g/hour * 500 mL) / 20 g = 50 mL/hour.
