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 ["63"]
Explanation
To calculate the infusion rate for the IV pump, the total volume of the IV fluid (250 mL) should be divided by the time over which the infusion is to take place (4 hours). This calculation results in an infusion rate of 62.5 mL/hr. Since the infusion pump cannot be set to a decimal, the rate is rounded to the nearest whole number, which is 63 mL/hr.
Correct Answer is ["25"]
Explanation
To calculate the volume of propranolol solution the client should self-administer per dose, you would divide the total daily dose by the concentration of the solution. The prescription is for 200 mg daily, to be taken in equal doses every 12 hours, which means each dose should be 100 mg. With the solution concentration at 4 mg/mL, you would divide 100 mg by 4 mg/mL to find the volume needed for one dose. This calculation results in 25 mL per dose.
