A nurse is preparing to administer cefaclor 500 mg PO every 12 hours. If the available cefaclor oral suspension is 250 mg/5 mL, how many mL should the nurse administer per dose?
Correct answer
5 mL
Rationale
Step 1: Determine cefaclor concentration: 250 mg ├À 5 mL = 50 mg/mL. Step 2: Calculate volume for 500 mg dose: 500 mg ├À 50 mg/mL = 10 mL. Thus, 10 mL is the correct dose.
