A client receives a prescription for hydromorphone 1 mg IV every 2 to 3 hours PRN for pain. The medication is available in a 2 mg/mL vial. How many mL should the nurse administer? (Enter numerical value only.)
The Correct Answer is ["0.5"]
Calculation:
Identify the desired dose:
Desired dose = 1 mg
Available concentration = 2 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 1 mg / 2 mg/mL
= 0.5 mL

Correct Answer is ["17"]
Explanation
Calculation:
Total volume to be infused = 150 mL
Infusion time in minutes = 90 minutes
Drop factor of the IV tubing = 10 drops/mL
Calculate the total number of drops to be infused:
Total drops = Total volume (mL) x Drop factor (drops/mL)
= 150 mL x 10 drops/mL
= 1500 drops
Calculate the infusion rate in drops per minute (drops/minute):
Infusion rate (drops/minute) = Total drops / Infusion time (minutes)
= 1500 drops / 90 minutes
≈ 16.67 drops/minute
Round to the nearest whole number:
= 17 drops/minute
Correct Answer is ["0.25"]
Explanation
Calculation:
Convert the child's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 55 pounds / 2.2 pounds/kg
= 25 kg
Calculate the prescribed dose in milligrams:
Dose (mg) = Prescribed dose (mg/kg) x Child's weight (kg)
= 0.01 mg/kg x 25 kg
= 0.25 mg
Calculate the volume to administer in mL:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 0.25 mg / 1 mg/mL
= 0.25 mL
Rounding to the nearest hundredth,
= 0.25 mL.
