Veterinary Technician Practice Exam

When taking an animal's temperature, which type of thermometer should be used?

1. Digital thermometer

2. Rectal thermometer

3. Infrared thermometer

4. Ear thermometer

The correct answer is: Rectal thermometer

Using a rectal thermometer is the preferred method for accurately measuring an animal's body temperature. This method allows for precise readings, which are critical in clinical settings for assessing an animal's health, especially in diagnosing fever or hypothermia. Rectal thermometers are designed specifically for this purpose and can provide quick and reliable results. Digital thermometers are also appropriate, but it’s important to ensure they are specifically meant for rectal use in animals, as there are different types of digital thermometers. Infrared and ear thermometers, while useful in certain situations, often provide less reliable readings in animals due to anatomical differences and the way temperature regulation works in various species. Therefore, for veterinary practice, rectal thermometers remain the gold standard for measuring body temperature accurately.
