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 ["200"]
Explanation
Given:
Total volume: 1000 mL
Time: 5 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1000 mL/5 hr = X mL/1 hr
Cross-multiplying gives us:
1000 mL x 1 hr = 5 hr x X mL
Simplifying:
1000 = 5X
Solving for X:
X = 1000 / 5 = 200 mL/hr
Correct Answer is ["2"]
Explanation
Given:
Prescribed dose: 100 mcg of fentanyl
Available concentration: 0.05 mg/mL
Steps to solve:
Convert mcg to mg:
1 mg = 1000 mcg
So, 100 mcg = 0.1 mg
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
0.05 mg/mL = 0.1 mg/X mL
Cross-multiplying gives us:
0.05 mg x X mL = 0.1 mg x 1 mL
Simplifying:
0.05X = 0.1
Solving for X:
X = 0.1 / 0.05 = 2 mL
