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 ["167"]
Explanation
Given:
Total volume: 1000 mL
Time: 6 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1000 mL/6 hr = X mL/1 hr
Cross-multiplying gives us:
1000 mL x 1 hr = 6 hr x X mL
Simplifying:
1000 = 6X
Solving for X:
X = 1000 / 6 = 166.67 mL/hr
Round to the nearest whole number:
167 mL/hr.
Correct Answer is ["0.67"]
Explanation
Given:
Prescribed dose: 5,000 units of heparin
Available concentration: 7,500 units/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
7,500 units/mL = 5,000 units/X mL
Cross-multiplying gives us:
7,500 units x X mL = 5,000 units x 1 mL
Simplifying:
7,500X = 5,000
Solving for X:
X = 5,000 / 7,500 = 0.67 mL
