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 ["4.8"]
Explanation
To calculate the IV pump setting for dobutamine administration, first determine the total mcg per minute for the newborn, which is 10 mcg/kg/min multiplied by the newborn's weight. For a 4 kg newborn, this would be 40 mcg/min. Next, convert the available dobutamine concentration to mcg/mL by dividing the total mg available by the volume in mL, resulting in 250 mg / 500 mL = 0.5 mg/mL, which is equivalent to 500 mcg/mL. Now, divide the newborn's required mcg/min by the concentration in mcg/mL to find the mL/min, which is 40 mcg/min / 500 mcg/mL = 0.08 mL/min. Finally, convert this to mL/hr by multiplying by 60, resulting in 4.8 mL/hr. After rounding to the nearest tenth, the IV pump should be set to deliver 4.8 mL/hr.
Correct Answer is ["0.5"]
Explanation
To administer the correct dose of ketorolac, which is 15 mg, and given that the available ketorolac injection concentration is 30 mg/mL, the nurse should use the following calculation: Divide the ordered dose (15 mg) by the concentration of the available medication (30 mg/mL). This results in 0.5 mL.
