A laboring client with preeclampsia is prescribed magnesium sulfate 2g/h IVPB.
The pharmacy sent the IV to the unit labeled magnesium sulfate 20g/500mL normal saline.
To administer the correct dose, the nurse should set the pump to deliver how many milliliters per hour?
The Correct Answer is ["50"]
Step 1: Calculate the concentration of magnesium sulfate. 20g ÷ 500mL = 0.04g/mL.
Step 2: Determine the required dose in grams per hour. 2g ÷ 1h = 2g/h
Step 3: Calculate the volume to be infused per hour. 2g ÷ 0.04g/mL = 50mL/h

Correct Answer is D
Explanation
Choice A rationale
Prescribing insulin is premature based on a single elevated glucose test without further diagnostic confirmation through a 3-hour Glucose Tolerance Test.
Choice B rationale
Increasing carbohydrate intake is not recommended for managing elevated glucose levels in gestational diabetes.
Choice C rationale
No changes are recommended only if the GTT results are within the expected range. Further testing is required due to the elevated result.
Choice D rationale
A 3-hour Glucose Tolerance Test is needed to confirm gestational diabetes following an elevated 1-hour test result to ensure accurate diagnosis and appropriate management.
