Free AAVSB Veterinary License Questions and Answers — Questions and Answers
Question 1: What is the most common cause of pyometra in dogs?
- Streptococcus
- Escherichia coli (Correct answer)
- Sttphlococcus
- Salmonella
Correct answer: Escherichia coli
Pyometra is a serious bacterial infection of the uterus, most commonly seen in intact female dogs. Escherichia coli (E. coli) is the most frequent bacterial isolate found in cases of pyometra, often ascending from the vagina. The hormonal changes during the estrous cycle, particularly progesterone, create an environment conducive to bacterial growth, leading to this life-threatening condition.
Question 2: Which of the following vaccines is considered a core vaccine for dogs?
- Leptospirosis
- Lyme disease
- Rabies (Correct answer)
- Canine influenza
Correct answer: Rabies
Core vaccines are those recommended for all dogs, regardless of lifestyle, due to the severity and prevalence of the diseases they protect against. Rabies is a fatal viral disease that can affect all mammals, including humans, making its vaccination a legal requirement in many areas and a critical public health measure. Other core vaccines typically include canine distemper, adenovirus, and parvovirus.
Question 3: In cats, which parasite is most commonly associated with causing anemia?
- Toxocara cati
- Ancylostoma tubaeforme (Correct answer)
- Dipylidium caninum
- Atenia taniaformis
Correct answer: Ancylostoma tubaeforme
Ancylostoma tubaeforme, commonly known as feline hookworm, is a significant intestinal parasite in cats. These worms attach to the lining of the small intestine and feed on blood, leading to blood loss. In heavy infestations, this blood loss can cause severe anemia, especially in kittens, making it the most common parasitic cause of anemia in felines.
Question 4: What s the average gestation period for a domestic cat?
- 58-65 days (Correct answer)
- 66-70 days
- 71-75 days
- 76-80 days
Correct answer: 58-65 days
The average gestation period for a domestic cat typically ranges from 58 to 65 days, or approximately 9 weeks. While there can be slight variations, this timeframe is generally accepted for a healthy pregnancy. Knowing this period is crucial for veterinarians and breeders to monitor the queen's health and prepare for parturition.
Question 5: Which medication is commonly used to induce emesis in dogs?
- Metoclopramide
- Apomorphine (Correct answer)
- Ondansetron
- Maropitant
Correct answer: Apomorphine
Apomorphine is a potent dopamine agonist that acts on the chemoreceptor trigger zone (CRTZ) in the brain, making it a highly effective emetic for dogs. It is commonly used in veterinary medicine to induce vomiting in cases of recent toxin ingestion, helping to prevent absorption of harmful substances. Its rapid action and reliability make it a preferred choice for this purpose.
