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

Explanation
Given:
Total volume to be infused: 50 mL
Infusion time: 30 minutes
Step 1: Convert infusion time to hours:
Infusion time (hr) = 30 min / 60 min/hr
Infusion time (hr) = 0.5 hr
Step 2: Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Step 3: Substitute the values:
Infusion rate (mL/hr) = 50 mL / 0.5 hr
Step 4: Calculate the infusion rate:
Infusion rate (mL/hr) = 100 mL/hr
Correct Answer is ["1"]
Explanation
Given:
Desired dose of nystatin: 100,000 units
Concentration of nystatin suspension: 100,000 units/mL
Step 1: Set up the proportion:
Desired dose (units) / Volume to administer (mL) = Concentration (units/mL)
Step 2: Substitute the values:
100,000 units / Volume = 100,000 units/mL
Step 3: Solve for the unknown volume:
Volume = 100,000 units / 100,000 units/mL
Step 4: Calculate the volume:
Volume = 1 mL
