Vet Science - Medication Calculations

Front

What is the formula to calculate the dosage of medication in mg/kg?

Back

Dosage (mg) = Weight (kg) x Dosage rate (mg/kg)

Front

How do you convert pounds to kilograms?

Back

1 pound = 0.453592 kg. To convert, multiply pounds by 0.453592.

Front

If a dog weighs 33 pounds, how much does it weigh in kilograms?

Back

33 pounds x 0.453592 = 14.97 kg (approximately 15 kg).

Front

What is the concentration of a medication if it is provided as 125 mg/5 mL?

Back

The concentration is 25 mg/mL (125 mg ÷ 5 mL).

Front

How do you determine how many tablets to give based on the total dosage required?

Back

Total dosage required (mg) ÷ Strength of each tablet (mg) = Number of tablets.

Front

What does BID mean in medication dosing?

Back

BID means 'bis in die' which is Latin for 'twice a day'.

Front

If a cat needs 15 mg/kg of medication and weighs 11 lbs, how do you calculate the total dosage?

Back

Convert 11 lbs to kg (11 lbs x 0.453592 = 5 kg). Then, Total dosage = 5 kg x 15 mg/kg = 75 mg.

Front

What is the total dosage for a dog weighing 88 lbs that requires 5 mg/kg?

Back

Convert 88 lbs to kg (88 lbs x 0.453592 = 39.92 kg). Total dosage = 39.92 kg x 5 mg/kg = 199.6 mg.

Front

How many mL of a medication do you give if the concentration is 10 IU/mL and the required dose is 1.5 IU/kg for a cat weighing 8.8 lbs?

Back

Convert 8.8 lbs to kg (8.8 lbs x 0.453592 = 4 kg). Required dose = 4 kg x 1.5 IU/kg = 6 IU. Volume = 6 IU ÷ 10 IU/mL = 0.6 mL.

Front

What is the total number of tablets needed if a dog requires 100 mg/kg and weighs 33 lbs?

Back

Convert 33 lbs to kg (33 lbs x 0.453592 = 15 kg). Total dosage = 15 kg x 100 mg/kg = 1500 mg. Tablets needed = 1500 mg ÷ 500 mg/tablet = 3 tablets.
