A nurse is preparing to administer magnesium sulfate 1 g/hr via continuous IV infusion to a client. Available is magnesium sulfate 40 g in 0.9% sodium chloride 000 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["25"]
To calculate the IV pump setting, you need to determine how many milliliters per hour will provide 1 gram of magnesium sulfate. With 40 grams of magnesium sulfate in 1000 mL, you have a concentration of 0.04 grams per mL. To administer 1 gram per hour, divide the desired dose (1 gram) by the concentration (0.04 grams/mL), which equals 25 mL. Therefore, the nurse should set the IV pump to deliver 25 mL per hour.

Correct Answer is ["125"]
Explanation
To calculate the infusion rate, the total volume of lactated Ringer's solution (500 mL) should be divided by the total time of infusion (4 hours). This results in an infusion rate of 125 mL/hr.
Correct Answer is ["2"]
Explanation
To calculate the correct dosage, the nurse needs to divide the total units prescribed by the concentration of units per milliliter available. In this case, 1,200,000 units prescribed divided by 600,000 units per mL results in 2 mL.
