A healthcare provider prescribes a maintenance dose of 2 grams per hour of intravenous magnesium sulfate for a client with preeclampsia.

The IV bag contains 20 grams of magnesium sulfate in 500 mL of 5% dextrose in water.

How many mL/hour should the nurse set the infusion pump to deliver? (Note: This is a medical math, so no options are provided.)

Answer and Explanation

The Correct Answer is ["50"]

To calculate the rate at which the infusion pump should be set, we need to determine how many mL of the solution contain 2 grams of magnesium sulfate.

Step 1: First, we find out how many grams of magnesium sulfate are in 1 mL of the solution. The IV bag contains 20 grams of magnesium sulfate in 500 mL, so we divide 20 grams by 500 mL to get the amount of magnesium sulfate per mL: 20 grams ÷ 500 mL = 0.04 grams/mL

Step 2: Next, we find out how many mL contain 2 grams of magnesium sulfate.

We divide 2 grams by the amount of magnesium sulfate per mL: 2 grams ÷ 0.04 grams/mL = 50 mL Therefore, the nurse should set the infusion pump to deliver 50 mL per hour.

A. Monitor blood pressure, pulse, and respirations every 4 hours. B. Keep an airway at the bedside. C. Allow liberal family visitation. D. Assess temperature every hour.

Correct Answer is B

Explanation

Choice A rationale

While monitoring vital signs is important in a client with eclampsia, it should be done more frequently than every 4 hours due to the risk of seizures and other complications.

Choice B rationale

Keeping an airway at the bedside is crucial for a client with eclampsia. If a seizure occurs, the airway can be used to ensure the client’s airway remains open.

Choice C rationale

Liberal family visitation may not be appropriate for a client with eclampsia who needs a quiet and stress-free environment to prevent triggering seizures.

Choice D rationale

Assessing temperature every hour is not specifically related to the care of a client with eclampsia.
