Assistant Laboratory Animal Technician (ALAT) Practice Exam

What should be monitored regularly in a laboratory mouse facility to ensure health?

1. Room temperature

2. Humidity levels

3. Food and water supply

4. All of the above

The correct answer is: All of the above

Monitoring all aspects of the environment and care in a laboratory mouse facility is crucial for ensuring the health and well-being of the animals. Regular checks on room temperature are essential because mice are sensitive to extreme temperature fluctuations. A temperature that is too high or too low can lead to stress, affecting their health and research outcomes. Humidity levels also play a significant role in maintaining the overall health of the mice. Too much humidity can lead to respiratory issues and humidity-related complications, while too little can cause dehydration and discomfort. Equally important is the monitoring of food and water supply. Mice require a consistent and adequate intake of food and clean water to thrive and maintain healthy growth rates. Inadequate nutrition or hydration can lead to significant health concerns and can influence experimental results. Therefore, ensuring that room temperature, humidity levels, and food and water supply are monitored regularly reflects a comprehensive approach to animal care in a laboratory setting. This holistic attention to environmental factors is key in promoting the health and welfare of laboratory mice.
