A nurse is preparing to administer nalbuphine 10 mg IV bolus to a client who is in labor. Available is nalbuphine 20 mg/mL. How many mL should the nurse plan to administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To administer the correct dose of nalbuphine, which is 10 mg, when you have a concentration of 20 mg/mL, you need to calculate the volume to be administered. The formula to use is: (Dose ordered / Drug concentration) = Volume to administer. Plugging in the values: (10 mg / 20 mg/mL) = 0.5 mL.

Correct Answer is ["25"]
Explanation
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 ["2"]
Explanation
To administer the correct dose of ciprofloxacin, which is 0.5 grams (g), the nurse needs to convert this amount into milligrams (mg) because the available tablets are measured in mg. There are 1000 mg in 1 g, so 0.5 g is equal to 500 mg. Since each tablet contains 250 mg, the nurse would need to administer two tablets to reach the prescribed dose of 500 mg.
