Question

three - year - old suzie came to the clinic with her mother. suzie has a sore throat. the provider diagnosed strep throat and ordered 45 mg/kg amoxicillin daily over three doses. you have amoxicillin 125 mg per 5ml. how many ml are you giving suzie with each dose? how many mls will suzie receive over 24 hours.

Explanation:

Step1: Calculate daily dose in mg

Assume Suzie's weight is not given, we'll work with the dose - per - kg information. The daily dose of amoxicillin is 45 mg/kg. Let's assume Suzie weighs 15 kg (a typical weight for a 3 - year - old). So the daily dose in mg is $45\times15 = 675$ mg.

Step2: Calculate volume for daily dose

We know that there are 125 mg per 5 mL. Let the volume of the daily dose be $V$. Using the proportion $\frac{125}{5}=\frac{675}{V}$, we can cross - multiply: $125V = 675\times5$, then $V=\frac{675\times5}{125}=27$ mL.

Step3: Calculate volume per dose

Since the daily dose is divided into 3 doses, the volume per dose is $\frac{27}{3}=9$ mL.

Answer:

Volume per dose: 9 mL
Volume over 24 hours: 27 mL
