An infant acetaminophen suspension contains 80 mg/0.80 ml suspension. the recommended dose is 15 mg/kg body? weight. how many ml of this suspension should be given to a child weighing 13 ibs. me, im at a total loss at how to approach this problem

First, the child's weight must be converted from pounds to kilograms. 1 lb is equal to 0.453592 kg, so a 13 lb child weighs: 13 lb * 0.453592 kg/lb = 5.896696 kg Next, use the child's converted weight to determine the mg dosage. The recommended dose is 15 mg per kg, so the recommended dose is: 15 mg/kg * 5.896696 kg = 88.45044 mg Finally, determine how many mL are needed to provide the calculated mg dosage. One unit of the suspension is 80 mg/0.80 mL. In order to provide 88.45044 mg, you will need 88.45044 mg / 80 mg = 1.1056305 units of the suspension. Multiplying this by the 0.80 mL portion of the unit of the suspension, you get the final mL dosage: 0.80 mL * 1.1056305 = 0.8845044 mL A 13 lb child should receive 0.8845044 mL of the 80mg/.8mL suspension.
