Question

1.A 39 kg post-operative splenectomy labrador retriever named “Joey” needs a dose of buprenex (buprenorphine) IV for pain management. The dose is 0.01 mg/kg IV. The concentration of buprenex is 0.5 mg/ml. How many mgs of buprenex will you give to “Joey”? How many mls of buprenex will you give “Joey”?

Answer 1

The weight of Joey is 39kg. Then, he needs to take:

$x=39kg(0.01\frac{mg}{\operatorname{kg}})=39\cdot0.01mg=0.39mg$

a) He needs to be given 0.39mg

b)On the other hand, 0.39mg in milliliters is:

$y=\frac{0.39mg}{0.5\frac{mg}{ml}}=\frac{0.39}{0.5}ml=0.78ml$

So, he needs to take 0.78ml
