you receive an order for ketorlac 30 mg iv q12h prn for pain. the stock supply is ketoralac 15 mg/ml. how many ml will you prepare per one dose injection?
450 ml
360 ml
60 ml
2 ml

Explanation:

Step1: Determine number of doses per day for amoxicillin

There are 24 hours in a day and the dose is every 8 hours ($q8h$), so the number of doses per day is $\frac{24}{8}=3$.

Step2: Calculate daily amoxicillin dose

Each dose is 250 mg, and with 3 doses per day, the daily dose is $250\times3 = 750$ mg.

Step3: Calculate volume for ketorolac dose

The ordered dose of ketorolac is 30 mg and the stock - supply is 15 mg/mL. Using the formula $V=\frac{D}{C}$ (where $V$ is volume, $D$ is dose, and $C$ is concentration), we have $V=\frac{30}{15}=2$ mL.

Answer:

First question: A. 750 mg
Second question: D. 2 mL
