A nurse is assisting with the care of a client who is scheduled for a cesarean birth. The nurse is preparing to administer cefazolin gin 0.9% sodium chloride 100 mL via Intermittent IV bolus over 15 min. The nurse should see 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"]
Given:
Total volume: 100 mL
Time: 15 minutes
Steps to solve:
Determine the flow rate in mL/min:
Set up a proportion to solve for the unknown flow rate (X):
100 mL/15 min = X mL/1 min
Cross-multiplying gives us:
100 mL x 1 min = 15 min x X mL
Simplifying:
100 = 15X
Solving for X:
X = 100 / 15 = 6.67 mL/min
Convert to mL/hr:
6.67 mL/min x 60 min/hr = 400 mL/hr

Correct Answer is ["1.5"]
Explanation
Given:
Prescribed dose: 75 mg of iron dextran
Available concentration: 50 mg/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
50 mg/mL = 75 mg/X mL
Cross-multiplying gives us:
50 mg x X mL = 75 mg x 1 mL
Simplifying:
50X = 75
Solving for X:
X = 75 / 50 = 1.5 mL
Correct Answer is ["5"]
Explanation
Given:
Prescribed dose: 20 mg of propranolol per dose
Available concentration: 4 mg/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
4 mg/mL = 20 mg/X mL
Cross-multiplying gives us:
4 mg x X mL = 20 mg x 1 mL
Simplifying:
4X = 20
Solving for X:
X = 20 / 4 = 5 mL
