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 ["3"]
Explanation
Given:
Prescribed dose: 30 mEq of potassium chloride per dose
Available tablets: 10 mEq tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 10 mEq tablets are needed to make 30 mEq of potassium chloride.
Set up a proportion to solve for the unknown number of tablets (X):
10 mEq/tablet = 30 mEq/X tablets
Cross-multiplying gives us:
10 mEq x X tablets = 30 mEq x 1 tablet
Simplifying:
10X = 30
Solving for X:
X = 30 / 10 = 3 tablets
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
