Answer:
Option C) 10
Step-by-step explanation:
We are given the following in the question:
Dose of antihistamine = 0.25 milligrams per pounds
Weight of dog = 18 kilograms
1 kg = 2.20462 pounds
Weight of dog in pounds =
[tex]=18\times 2.20462\\=39.68\text{ pounds}[/tex]
Dose of antihistamine given to dog =
[tex]=\text{Weight of dog}\times {\text{Unit dose}\\=39.68\times 0.25\\=9.92\\\approx 10[/tex]
Thus, 10 milligrams of antihistamine that should be administered to a dog weighing 18 kilograms.
Option C) 10
