The nurse is preparing a dose of ketorolac 12 mg IV using a 1 mL vial containing 30 mg/mL. How many mL should the nurse administer? (Enter numerical value only.)
The Correct Answer is ["0.4"]
here's how to calculate the volume (mL) of ketorolac the nurse should administer:
1. Dose of ketorolac to administer:
Dose = 12 mg (given)
2. Concentration of ketorolac in the vial:
Concentration = 30 mg/mL (given)
3. We need to find the volume (mL) containing the prescribed dose (12 mg) considering the concentration (30 mg/mL) in the vial.
Volume to administer (mL): Dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 12 mg / 30 mg/mL
Volume to administer (mL) = 0.4 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 0.4 mL of ketorolac intravenously.

Correct Answer is ["100"]
Explanation
The nurse should set the infusion pump to deliver the entire 150 mL over the course of 90 minutes.
First, convert the time from minutes to hours because the rate is required in mL/hr.
90 minutes is 1.5 hours (since 1 hour = 60 minutes).
Therefore, the IV pump should be set to deliver:
Rate(mL/hr)=Time(hr)Totalvolume(mL)=1.5hr150mL
After performing the calculation, we find that the rate equals 100 mL/hr.
So, the nurse should set the infusion pump to deliver 100 mL/hr. This is rounded to the nearest whole number as per the instructions.
