ALAT - Assistant Laboratory Animal Technician Animal Health and Welfare Questions and Answers

Question 1

An assistant laboratory animal technician observes a mouse in its cage hunched in a corner, with ruffled fur and squinted eyes. The mouse is also less active than its cagemates. Which of the following conditions do these signs most likely indicate?

Accepted Answer

Pain or distress

Answer

Signs such as a hunched posture, piloerection (ruffled fur), squinted eyes (grimace scale), and decreased activity are common indicators of pain, illness, or distress in rodents. It is a crucial part of an ALAT's responsibility to recognize and report these signs promptly.

Question 2

Which of the following is an essential component of an environmental enrichment program for laboratory animals?

Accepted Answer

Providing opportunities for species-typical behaviors

Answer

Environmental enrichment aims to enhance animal well-being by providing stimuli that allow animals to perform species-typical behaviors, such as nesting, foraging, or gnawing. This helps reduce stress and abnormal behaviors.

Question 3

According to the AVMA Guidelines for the Euthanasia of Animals, what is a critical requirement for a method to be considered 'acceptable'?

Accepted Answer

It must consistently produce a humane death with minimal pain and distress.

Answer

The primary principle of the AVMA Guidelines for the Euthanasia of Animals is that the method should consistently induce a rapid loss of consciousness followed by cardiac or respiratory arrest and death, with minimal pain, distress, or anxiety for the animal.

Question 4

While performing daily health checks, an ALAT notices a rabbit that has not produced any fecal pellets in the last 24 hours and is showing a decreased appetite. What is the most appropriate immediate action?

Accepted Answer

Report the observation to the veterinary staff or supervisor immediately.

Answer

Decreased or absent fecal production (gastrointestinal stasis) is a serious and potentially life-threatening condition in rabbits that requires prompt veterinary attention. An ALAT's responsibility is to observe and report any abnormalities in animal health to the veterinary team without delay.

Accepted Answer

The Guide for the Care and Use of Laboratory Animals
