Correct Answer is C

Explanation

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.

A. 1.71 mL B. 5.7 mL C. 10 mL D. 17.1 mL

Correct Answer is B

Explanation

The amount of solution the nurse should withdraw from the vial can be calculated using the following formula:

Amount of solution = Amount of medication needed / Concentration of medication in the solution.

In this case, the amount of medication needed is 17.1 mg and the concentration of medication in the solution is 3 mg/mL. Substituting these values into the formula, we get:

Amount of solution = 17.1 mg / 3 mg/mL = 5.7 mL

Therefore, the answer is B. The nurse should withdraw 5.7 mL of solution from the vial.
