Most veterinary drug dosages are weight-based. The basic process involves two main steps:
Always convert pounds (lb) to kilograms (kg) first by dividing by 2.2 ( Mass: The basic process involves two main steps: Always
Total Dose (mg)=Patient Weight (kg)×Dose Rate (mg/kg)Total Dose (mg) equals Patient Weight (kg) cross Dose Rate (mg/kg)
To convert a percentage to mg/mL, multiply by 10 (e.g., a 2% solution is Advanced Calculations The top 5 drug calculations every vet nurse needs to know multiply by 10 (e.g.
Consistency in units is critical to prevent significant errors.
