Suppose that sodium pentobarbital is used to anesthetize a dog. The dog is anesthetized when its bloodstream contains at least 45 milligrams (mg) of sodium pentobarbital per kilogram of the dog's body weight. Suppose also that sodium pentobarbital is eliminated exponentially from the dog's bloodstream, with a half-life of 5 hours. What single dose should be administered in order to anesthetize a 50-kg dog for 1 hour?

Step 1
The dog needs at least 45 mg of sodium pentobarbital per kilogram of body weight. For a 50-kg dog, the required amount is: \[ 45 \, \text{mg/kg} \times 50 \, \text{kg} = 2250 \, \text{mg} \] Show more…

A dog is anesthetized when its bloodstream contains at least 45 milligrams (mg) of the anesthetic sodium pentobarbital per kilogram of the dog's body weight. Suppose that the sodium pentobarbital is eliminated exponentially from the dog's bloodstream, with a half-life of 5 hours. What single dose should be administered in order to anesthetize a 70-kg dog for 1 hour?

Pentobarbital Sodium is a drug often used to anesthetize dogs and is known to decay exponentially with a half-life of 5 hours. The dog is anesthetized when its bloodstream contains 45 mg of the drug per kg of the dog's body weight. How much Pentobarbital Sodium needs to be administered at the beginning for a 60 kg dog to prepare for a 3-hour surgery so that it stays anesthetized for the entire surgery period?
