The healthcare provider prescribes cefixime oral suspension 200 mg PO twice a day for an older adult who has difficulty swallowing tablets. The bottle is labeled, "Cefixime for Oral Suspension, USP 100 mg per 5 mL." How many mL should the nurse administer daily? (Enter numerical value only.)

The prescribed dosage is 200 mg twice a day, so the total daily dosage in mg would be: Daily dosage in mg = 2 × Dosage per dose = 2 × 200mg = 400mg The medication is available in a concentration of 100 mg/5 mL. Therefore, the volume to be administered per day in mL would be: Volume in mL = Daily dosage in mg / Concentration in mg/mL ​= 400mg / 20mg/mL​ = 20mL So, the nurse should administer 20 mL of cefixime oral suspension per day.
