Introduce the course mastering veterinary calculations and outline the pathway to develop core veterinary calculations skills.
Calculate veterinary dosages using the formula (dose mg/kg × weight) ÷ concentration mg/mL, emphasizing units, with amoxicillin 12.5–25 mg/kg dose for a urinary tract infection in a 25 kg patient.
Calculate the feline dose using 22 mg/kg for a 4 kg cat with a 250 mg/5 ml solution for a susceptible skin infection, yielding about 1.76 ml.
Practice dosage calculations for fentanyl citrate in dogs and cats, converting 0.05 mg/ml to micrograms and applying 10 mcg/kg for a 12 kg patient to yield 2.4 ml IV.
Learn prescription writing in veterinary medicine with a two-line format: line one lists drug name, concentration, and formulation; line two lists quantity, route, frequency, duration, with regional legal variations.
Learn how to write compounded prescriptions, calculate dosing from mg/kg, convert weights to kilograms, adjust tablet concentrations, and address regional regulatory differences in veterinary practice.
Learn to calculate dogs' and cats' energy needs using resting energy requirements (rer) and daily energy requirements (DVR) with growth and maintenance coefficients, then plan feeding and note refeeding syndrome.
Calculate resting energy requirements and progressive food intake for malnourished animals using 25% increments, convert food labels to calories, and plan multi-meal feeding.
Finish mastering veterinary calculations by reviewing key concepts from the course and outlining practical next steps for applying calculation skills in veterinary practice.
This document contains the most used Veterinary Calculations and Prescription writing skills that will be useful for the entirety of your Veterinary careers.
Practice these calculations and prescription writing from your inception into Veterinary Medicine to ensure it becomes second nature by final year. Remember that our fraternity prides ourselves on tailoring volumes to our wide array of patients. Always bear in mind that it’s lives we are dealing with.
The covered topics include:
1) Dosage calculations - this will aid you in calculating the accurate volumes of drugs to administer to your patients and thus will eliminate inaccurate drug volumes from being administered, which can either be detrimental if volumes are too high or may not have the desired effect if volumes are low.
2) Prescription writing - accurate prescription writing skills is a must. Knowing what information to include and the format is the foundation of any accurate prescription.
This skill compliments dosage calculations and is THE MOST WIDELY used duo in Veterinary Medicine.
3) Dilution calculations - due to the unavailability of some drug concentrations, dilutions are commonly used in Veterinary medicine, therefore you must be equipped with the right knowledge and information to perform these calculations confidently and accurately.
4) Resting energy requirement and (5) daily energy requirement calculations for both healthy and malnourished patients. This serves as a guide for your patients and significantly diminishes refeeding syndrome in companion animals.
