Question

a solution contains 65 mg/ml of sodium pentobarbital. What volume of this drug would be appropriate to administer to a 300 g laboratory rat at dose of 40 mg/kg

Answer 1

Answer:

0.18 ml would be appropriate

Explanation:

• 1kg   ↔   1000mg

         x     ↔   300mg

         x = 0.3 kg

therefore;    40 ×  0.3  = 12 mg/kg

• 65     ↔     1ml

        12      ↔     y    

         y   = 0.18 ml
