A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 mL via intermittent IV bolus over 15 min to a client who is scheduled for a cesarean birth. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["400"]
Total Volume: 100 mL
Total Time: 15 min
Convert the infusion time from minutes to hours.
Time (hr) = 15 min / 60 min/hr
= 0.25 hr.
Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total volume (mL) / Total time (hr)
= 100 mL / 0.25 hr
= 400 mL/hr.

Correct Answer is ["2"]
Explanation
Desired dose: 4 mg
Available concentration: 2 mg/mL
Calculate the volume to administer in milliliters (mL).
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
= 4 mg / 2 mg/mL
= 2 mL.
Correct Answer is ["0.5"]
Explanation
Desired dose: 5,000 units
Available concentration: 10,000 units/mL
Calculate the volume to administer in milliliters (mL).
Volume (mL) = Desired Dose (units) / Available Concentration (units/mL)
= 5,000units/10,000units/mL
= 0.5mL.
