A physician orders 525 milligrams (mg) of Cefaclor suspension for a patient with pharyngitis. Cefaclor is available as 375 mg/5 mL of solution. How many milliliters should be given?
Answer:
7 milliliters of solution
Required cefaclor = 525 milligram
Available cefaclor = 375 mg in 5 mL solution
375 mg = 5 mL solution
1 mg = 5/375 mL solution
525 mg = (5/375) ×525 mL = 7 mL solution.
Hence, 7 millilitres of solution should be given.
