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 ["10"]
Explanation
To administer the correct dose of docusate sodium liquid, which is 50 mg per 5 mL, for a total daily prescription of 200 mg, the nurse would need to give two equally divided doses. This means each dose should be 100 mg. To calculate the amount in milliliters for each dose, the nurse would use the following ratio: 50 mg is to 5 mL as 100 mg is to X mL. Solving for X, the calculation is (100 mg * 5 mL) / 50 mg, which equals 10 mL.
