A nurse is preparing to administer ciprofloxacin 250 mg PO every 12 hr. Available is ciprofloxacin 100 mg tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.5"]
Given:
Prescribed dose: 250 mg of ciprofloxacin per dose
Available tablets: 100 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 100 mg tablets are needed to make 250 mg of ciprofloxacin.
Set up a proportion to solve for the unknown number of tablets (X):
100 mg/tablet = 250 mg/X tablets
Cross-multiplying gives us:
100 mg x X tablets = 250 mg x 1 tablet
Simplifying:
100X = 250
Solving for X:
X = 250 / 100 = 2.5 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
Correct Answer is ["2722"]
Explanation
Let's convert pounds to grams.
We know that 1 pound= 453.592 grams.
Convert 6 pounds to grams, we multiply:
6 pounds x 453.592 grams/pound = 2721.552 grams
Rounding this to the nearest whole number gives 2722 grams.
