A nurse is assisting with the care of a client who is experiencing labor pain and is preparing to administer nalbuphine 10 mg IM. Available is nalbuphine solution for injection 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"]
Desired dose of nalbuphine: 10 mg
Concentration of nalbuphine solution: 20 mg/mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
10 mg / Volume = 20 mg/mL
Step 3: Solve for the unknown volume:
Volume = 10 mg / 20 mg/mL
Step 4: Calculate the volume:
Volume = 0.5 mL

Desired dose of magnesium sulfate: 2 g/hr
Concentration of magnesium sulfate solution: 40 g in 1,000 mL
Step 1: Calculate the desired volume of magnesium sulfate per hour:
Volume of magnesium sulfate per hour = Desired dose (g/hr) / Concentration (g/mL)
Volume of magnesium sulfate per hour = 2 g/hr / (40 g / 1,000 mL)
Volume of magnesium sulfate per hour = 2 g/hr / 0.04 g/mL
Volume of magnesium sulfate per hour = 50 mL/hr
