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.)

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
