Final answer:
Sodium pentobarbital is used by veterinarians to humanely euthanize animals. This injectable anesthetic is chosen for its rapid and peaceful effect, ensuring a painless ending for animals that are suffering or terminally ill. Option 1 is correct.
Step-by-step explanation:
Veterinarians use sodium pentobarbital primarily for euthanizing animals. This barbiturate is an injectable anesthetic that can induce unconsciousness rapidly. In veterinary medicine, sodium pentobarbital is selected for its efficiency to humanely end the life of suffering or terminally ill animals.
Unlike its use in general anesthesia, epilepsy, and acute migraine treatments in humans, this substance is utilized in animals when euthanasia is the chosen course of action. The injection ensures a peaceful and painless passing for the animal.
