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 ["188"]
Explanation
Given:
Total volume: 1500 mL
Time: 8 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1500 mL/8 hr = X mL/1 hr
Cross-multiplying gives us:
1500 mL x 1 hr = 8 hr x X mL
Simplifying:
1500 = 8X
Solving for X:
X = 1500 / 8 = 187.5 mL/hr
Round to the nearest whole number:
188 mL/hr.
Correct Answer is ["0.5"]
Explanation
Given:
Prescribed dose: 12.5 mg of promethazine
Available tablets: 25 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 25 mg tablets are needed to make 12.5 mg of promethazine.
Set up a proportion to solve for the unknown number of tablets (X):
25 mg/tablet = 12.5 mg/X tablets
Cross-multiplying gives us:
25 mg x X tablets = 12.5 mg x 1 tablet
Simplifying:
25X = 12.5
Solving for X:
X = 12.5 / 25 = 0.5 tablets
