✍️ Sample CET Questions & Answers
1. What is the CET's obligation when witnessing a colleague performing euthanasia improperly?
CETs have a professional and ethical obligation to report improper euthanasia practices to a supervisor and document the incident to protect animal welfare and maintain standards.
2. The breakdown mechanism in heavily doped, thin-junction diodes at low reverse voltages is called:
Zener (or tunneling) breakdown occurs in heavily doped junctions where the strong electric field allows electrons to tunnel through the narrow barrier.
3. Which physical sign is NOT a reliable indicator of death in animals after euthanasia?
Muscle twitching and agonal gasps are normal post-death neurological events and do not indicate the animal is still alive.
4. What is the key difference between a depletion-mode and an enhancement-mode MOSFET?
Depletion-mode MOSFETs are fabricated with a pre-existing channel, so they conduct at VGS = 0; enhancement-mode devices require an applied VGS to form the channel.
5. What is a race condition in embedded firmware?
A race condition arises when the outcome of concurrent accesses to shared data depends on the unpredictable order of execution, leading to intermittent bugs.
6. What should be done to prevent accidental exposure to euthanasia drugs?
Using syringes specifically designed for euthanasia drugs helps prevent accidental exposure by ensuring proper dosage and secure administration. These syringes often have features that minimize leakage or accidental needle sticks. This specialized equipment is a critical safety measure to protect technicians from potent and potentially dangerous substances.
