A nurse is preparing to administer amoxicillin 250 mg PO every 8 hr. The amount available is amoxicillin oral suspension 400 mg/5 mL. How many mL 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.)

This is incorrect B. This is incorrect C. This is incorrect D. Step 1: Use the formula Amount to administer (mL) = (Desired dose ÷ Dose available) × Volume available Step 2: Insert known values Desired dose = 250 mg Dose available = 400 mg Volume available = 5 mL Amount to administer = (250 ÷ 400) × 5 Amount to administer = 0.625 × 5 Amount to administer = 3.125 Step 3: Round to the nearest tenth 3.125 = 3.1 mL
