What is the normal respiratory rate range for an adult mouse?
Answer: 60-220 breaths/min
Adult mice have a normal respiratory rate of approximately 60-220 breaths per minute due to their high metabolic rate.
Which clinical sign in a rat most strongly suggests dehydration?
Answer: Skin tenting over the scruff
Skin tenting (decreased skin turgor) is a classic clinical sign of dehydration. When the skin is pulled and released, it remains elevated or returns slowly in dehydrated animals.
What is the primary function of the cecum in rabbits?
Answer: Fermentation of fibrous plant material
The rabbit cecum is a large fermentation chamber where symbiotic microorganisms break down cellulose and other fibrous plant materials.
Which blood collection site is most commonly used for routine sampling in mice?
Answer: Submandibular vein
The submandibular (facial) vein is the most commonly used site for routine blood collection in mice, allowing quick sampling with minimal restraint.
What does a hunched posture in a laboratory rodent typically indicate?
Answer: Pain or discomfort
A hunched posture in rodents is a well-recognized indicator of pain or discomfort and is a key component used in grimace scales for pain assessment.
What is the average gestation period for a guinea pig?
Answer: 59-72 days
Guinea pigs have a relatively long gestation period of 59-72 days compared to other laboratory rodents, resulting in precocial offspring born fully furred with open eyes.
