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.

Explanation
To calculate the infusion pump rate for a maintenance dose of magnesium sulfate, you need to determine how many milliliters per hour (mL/hr) will provide 4 grams (g) of magnesium sulfate per hour. Given that the pharmacy provides a 1-liter bag with 30 g of magnesium sulfate, this means there are 30,000 milligrams (mg) in 1,000 milliliters (mL) of solution. Since 1 g equals 1,000 mg, you need to administer 4,000 mg of magnesium sulfate per hour. To find the rate, divide the total amount of magnesium sulfate in the bag by the desired hourly dose: 30,000 mg divided by 4,000 mg per hour equals 7.5 hours of infusion time. Therefore, to administer the maintenance dose over one hour, you would set the infusion pump to 1,000 mL divided by 7.5 hours, which equals approximately 133.33 mL/hr = 133 mL/hr rounded off to the nearest whole number.
Correct Answer is D
Explanation
A. Administering a lactated Ringer's IV bolus is not indicated for vaginal bleeding and would not address the underlying issue.
B. Applying an ice pack to the incision site does not address the postpartum bleeding and is not appropriate.
C. Replacing the surgical dressing is important for wound care but does not address the ongoing vaginal bleeding.
D. Evaluating urinary output is essential to assess for possible urinary retention, which can contribute to uterine atony and postpartum bleeding. This assessment helps the nurse determine the client's fluid balance and potential causes of bleeding.
