A nurse is caring for a preschooler who has heart failure and a new prescription for furosemide 4 mg/kg every 8 hr. The child weighs 16 kg (35 lb). Available is furosemide oral solution 40 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
