The strength of Kefexin oral suspension is 100 mg/ml. Nora has been prescribed cefalexin at a dose of 50 mg/kg/day divided in two single doses. Nora weighs 14 kg. How many milliliters of solution for Nora should be given as a single dose?

To calculate the number of milliliters (ml) of Kefexin oral suspension that Nora should be given for a single dose, you can follow these steps: Determine the total daily dose for Nora: Nora's weight is 14 kg, and she has been prescribed a dose of 50 mg/kg/day. So, the total daily dose for Nora is: Total Daily Dose = Weight (kg) × Dose (mg/kg/day) Total Daily Dose = 14 kg × 50 mg/kg/day Total Daily Dose = 700 mg/day Since she is to be given the total daily dose divided into two single doses, you need to calculate the dose for a single administration: Dose per Single Administration = Total Daily Dose / Number of Doses per Day Dose per Single Administration = 700 mg / 2 Dose per Single Administration = 350 mg Now, you need to convert the dose from milligrams (mg) to milliliters (ml) using the concentration of the oral suspension, which is 100 mg/ml: Dose in Milliliters = Dose in Milligrams / Concentration (mg/ml) Dose in Milliliters = 350 mg / 100 mg/ml Dose in Milliliters = 3.5 ml So, Nora should be given 3.5 milliliters of Kefexin oral suspension for each single dose.
