Let's consider a 35 kg child requires amoxicillin at a dose of 50 mg/kg/day divided into 4 doses. If the amoxicillin suspension comes in 250 mg/ 5 mL, how many mL does the child require every 6 hours?

To calculate how many milliliters (mL) of amoxicillin suspension the child requires every 6 hours, you can follow these steps: Step 1: Calculate the total daily dose of amoxicillin for the child. The child's weight is 35 kg, and the dose is 50 mg/kg/day. So, the total daily dose is: Total Daily Dose = Weight (kg) × Dose (mg/kg/day) Total Daily Dose = 35 kg × 50 mg/kg/day Total Daily Dose = 1750 mg/day Step 2: Divide the total daily dose into 4 equal doses since the medication is to be divided into 4 doses a day. Each dose = Total Daily Dose / Number of Doses per Day Each dose = 1750 mg / 4 Each dose = 437.5 mg Step 3: Determine how many milliliters are needed for each dose. The amoxicillin suspension comes in a concentration of 250 mg per 5 mL. To find out how many mL are needed for each dose of 437.5 mg, you can set up a proportion: (250 mg) / (5 mL) = (437.5 mg) / (x mL) Cross-multiply: 250 * x = 437.5 * 5 Now, solve for x (the number of mL needed for each dose): x = (437.5 * 5) / 250 x = 2187.5 / 250 x = 8.75 mL So, the child requires 8.75 mL of amoxicillin suspension every 6 hours.
