The VTNE will have several questions for which you will need to perform calculations. We will be having several blog posts on how to do different types of calculations. It is good review for in-clinic use as well as studying for the VTNE. Here is a quick review of how to calculate a dose of injectable medication. We want you to know how to calculate pet drug dosage.
"Sparky" is a 5-year old male neutered Corgi mix and is currently in the hospital. He weighs 32 pounds. The doctor asks you to give Sparky 5 mg/kg of Baytril injectable antibiotic IV over 20 minutes. How much Baytril (in milliliters) will you give Sparky? The bottle says that Baytril is a 2.27% solution.
You will give your patient 3.2 mLs (the equivalent of 72.5 mg) of a 22.7 mg/mL Baytril solution IV over 20 minutes. Always double check your dose before administering to the patient.
Check the bottle, the syringe, the patient's chart, and that you have the correct patient. I know this seems obvious but is very important. Another thing to do is label the syringe when medication is drawn up so there are no mix-ups.
