A nurse is assisting with the care of a newborn and is preparing to administer ibuprofen 10 mg PO. Available is ibuprofen suspension 50mg/25 mL. How many mL should the nurse administer? Round the answer to the nearest hundredth, use a leading zero if it applies. Do not use a trailing zero.
The Correct Answer is ["5"]
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 hundredth:
5mL

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 ["400"]
Explanation
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
