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.

Correct Answer is ["300"]

Explanation

Step 1:

4 grams ÷ 20 grams × 500 mL = 100 mL

Step 2:

100 mL ÷ 20 minutes × 60 minutes/hour = 300 mL/hour

Answer:

300 mL/hour

A. Heat loss. B. Hypoglycemia. C. Fluid balance. D. Bleeding tendencies.

Correct Answer is A

Explanation

Choice A rationale

Heat loss is a significant concern for newborns immediately after birth. Newborns have a large surface area relative to their body weight, which makes them more susceptible to heat loss.

Maintaining a warm environment is crucial to prevent hypothermia, which can lead to complications such as hypoglycemia and respiratory distress.

Choice B rationale

While hypoglycemia is a concern in newborns, especially those born to mothers with diabetes, it is not the immediate priority in this scenario. The first step in stabilizing a newborn after birth is to ensure adequate respirations and prevent heat loss.

Choice C rationale

Fluid balance is important in newborns, but it is not the immediate priority in this scenario. The first step in stabilizing a newborn after birth is to ensure adequate respirations and prevent heat loss.

Choice D rationale

While newborns do have immature clotting mechanisms, making them more prone to bleeding tendencies, this is not the immediate priority in this scenario. The first step in stabilizing a newborn after birth is to ensure adequate respirations and prevent heat loss.
