Assistant Laboratory Animal Technician (ALAT) Practice Exam

What is the worst possible outcome if a rack of animals is disconnected from their water supply?

1. Dehydration

2. They could die

3. Increased stress levels

4. Broken cages

The correct answer is: They could die

The worst possible outcome of disconnecting a rack of animals from their water supply is indeed the potential for them to die. Each option represents a serious concern, but death, as a final and irreversible outcome, stands as the most severe consequence. When animals lose access to water, they can quickly become dehydrated, which is the initial stage of a detrimental process. While dehydration can lead to increased stress and various health complications, it is the culmination of these issues that may ultimately result in mortality if the situation is not addressed promptly. In a laboratory setting, maintaining animal welfare is critical, and ensuring a continuous water supply is a fundamental part of that responsibility. Dehydration, while serious, is a stepping stone to a more dire outcome, and increased stress levels can also manifest as a result of inadequate hydration, affecting overall well-being. Broken cages, although problematic, primarily concern the animals' living conditions rather than their immediate survival. Therefore, the potential for death from a lack of water is the gravest concern.
