A nurse is assisting with the care of a client who is in labor and is receiving penicillin G 5.000.000 units via intermittent IV bolus over 60 min. Available is penicillin G 5,000,000 units in 0.9% sodium chloride 100 mL. The nurse should ensure that the IV pump is set 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 ["100"]
Given:
Total volume: 100 mL
Time: 60 minutes
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
100 mL/60 min = X mL/1 min
Cross-multiplying gives us:
100 mL x 1 min = 60 min x X mL
Simplifying:
100 = 60X
Solving for X:
X = 100 / 60 = 1.67 mL/min
Convert to mL/hr:
1.67 mL/min x 60 min/hr = 100 mL/hr

Correct Answer is ["2"]
Explanation
Given:
Total daily dose: 300 mg of propylthiouracil per day
Number of doses per day: 3 doses
Available tablets: 50 mg tablets
Steps to solve:
Determine the dose per administration:
Since the daily dose is divided into three doses, each dose will be: 300 mg/day ÷ 3 doses/day = 100 mg/dose
Determine the number of tablets per dose:
Find how many 50 mg tablets are needed to make 100 mg of propylthiouracil.
Set up a proportion to solve for the unknown number of tablets (X):
50 mg/tablet = 100 mg/X tablets
Cross-multiplying gives us:
50 mg x X tablets = 100 mg x 1 tablet
Simplifying:
50X = 100
Solving for X:
X = 100 / 50 = 2 tablets
Correct Answer is ["5"]
Explanation
Set up a proportion:
You have 50 mg of ibuprofen in 25 mL of suspension.
You need to administer 10 mg of ibuprofen.
Let 'x' represent the unknown volume in mL.
The proportion is: 50 mg / 25 mL = 10 mg / x mL
2. Solve for x:
Cross-multiply: 50 x x = 25 x 10
Simplify: 50x = 250
Divide both sides by 50: x = 250 / 50
Calculate: x = 5 mL
3. Round to the nearest whole number:
5mL
