Final answer:
To calculate the dosage of Atropine for a 3.5 lb terrier, convert the weight from pounds to kilograms and then multiply it by the given dosage. The terrier would receive approximately 0.795 mg of Atropine.
Step-by-step explanation:
To calculate the amount of Atropine a 3.5 lb terrier would receive, we need to convert the weight from pounds to kilograms. There are 2.2 pounds in 1 kilogram. Therefore, the terrier weighs approximately 1.59 kilograms (3.5 lb ÷ 2.2 lb/kg).
Next, we can calculate the dosage by multiplying the weight in kilograms by the given dosage in milligrams per kilogram: 1.59 kg × 0.5 mg/kg = 0.795 mg.
Therefore, a 3.5 lb terrier would receive approximately 0.795 mg of Atropine.
