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 ["0.5"]
Explanation
To calculate the correct dosage of heparin, the nurse needs to use the formula: (desired dose ÷ available concentration) = volume to administer. In this case, the desired dose is 5,000 units, and the available concentration is 10,000 units per mL. Therefore, the calculation would be: (5,000 units ÷ 10,000 units/mL) = 0.5 mL. So, the nurse should administer 0.5 mL of heparin to the client. This dosage should be validated with another nurse to ensure accuracy and safety for the client.
Correct Answer is ["2"]
Explanation
To administer a dose of 5 mg of glyburide when only 2.5 mg tablets are available, the nurse would need to give two tablets. This is because each tablet contains 2.5 mg, and two tablets would equal the prescribed 5 mg dose.
