A physician orders magnesium sulfate, 6 grams loading dose to be administered over 30 minutes. There are 40 grams of magnesium sulfate in the IV bag. What is the rate per hour to administer the loading dose?

75 mL/hr

150 mL/hr

300 mL/hr

450 mL/hr

Answer and Explanation

The Correct Answer is C

To calculate the rate per hour, divide the amount of magnesium sulfate to be administered by the concentration of magnesium sulfate in the IV bag:

6 grams ÷ 40 grams = 0.15

Then, multiply the result by the volume of the IV bag, which is usually 1000 mL: 0.15 x 1000 mL = 150 mL

This is the amount of fluid that contains 6 grams of magnesium sulfate. To administer this amount over 30 minutes, multiply by 2 to get the rate per hour:

150 mL x 2 = 300 mL/hr.

Correct Answer is A

Explanation

To administer 1 mg of Stadol, we need 1/2 mL of 2 mg/mL injectable solution. .

So, to administer 1 mg of Stadol, the nurse should administer 0.5 mL of the injectable solution.

A. 1125 mg/dose B. 1237.5 mg/dose C. 2475 mg/dose D. 6544.5 mg/dose

Correct Answer is A

Explanation

First, we need to convert the weight of the child from pounds to kilograms:. 99 lb / 2.2046 = 44.91 kg (rounded to two decimal places).

Next, we can calculate the dose of carmustine:. 25 mg/kg x 44.91 kg = 1,122.75 mg.

We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 1,122.75 mg seems reasonable for a child with Hodgkin disease..

Since the medication is prescribed daily, the nurse should administer the calculated dose of 1,122.75 mg of carmustine to the child every day.
