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

0.18 ml would be appropriate

Step-by-step explanation:

• 1kg ↔ 1000mg

x ↔ 300mg

x = 0.3 kg

therefore; 40 × 0.3 = 12 mg/kg

• 65 ↔ 1ml

12 ↔ y

y = 0.18 ml
