Question

The vet orders Phenylbutazone to be given to an 800 lb horse at a dosage of 5 mg/kg. The drug concentration is 200 mg/mL. How many mL should be given?​

Answer 1

To calculate the amount of Phenylbutazone to be administered to an 800 lb horse, we need to determine the total dosage by multiplying the weight in kg by the dosage.

Step-by-step explanation:

To calculate the amount of Phenylbutazone to be administered, we need to follow the given dosage instructions. First, we need to calculate the total dosage of the drug for an 800 lb horse. The dosage is 5 mg/kg, so for an 800 lb horse, the weight in kg would be 800 lbs / 2.2 kg/lb = 363.64 kg. Multiplying this weight by the dosage, we get 363.64 kg x 5 mg/kg = 1818.18 mg.

Next, we need to convert the drug concentration from mg/mL to mL. The concentration is 200 mg/mL, so we divide the total dosage (1818.18 mg) by the concentration (200 mg/mL) to find the volume: 1818.18 mg / 200 mg/mL = 9.09 mL. Therefore, 9.09 mL of Phenylbutazone should be given to the horse.
