NACA Animal Control Officers Practice Test

What do mitotic pupils indicate in an animal?

1. Wide pupils suggesting brain damage

2. Pupils that are constricted and responsive

3. Pupils that do not react to light

4. Normal pupil size

The correct answer is: Pupils that are constricted and responsive

The term "mitotic pupils" refers to pupils that are constricted, which typically indicates a physiological or neurological response. When pupils are constricted and responsive, it often suggests that the animal is in a state of relaxation or is protected from overstimulation. This condition is generally observed in well-behaved animals or those under certain types of medication that promote calmness. In the context of veterinary medicine or animal control, observing that an animal has mitotic pupils can be important when assessing its health or behavior. For example, constricted pupils can point to the influence of certain drugs, such as opioids, which can affect pupil size. Moreover, responsive constricted pupils could indicate neurological function as they still react to stimuli, illustrating that the animal is capable of processing visual information. This knowledge helps an animal control officer make informed decisions regarding the animal's welfare and appropriate handling strategies. In contrast, the other options describe scenarios that involve either abnormal pupil responses, such as wide pupils suggesting potential brain damage, pupils that do not react to light indicating advanced neurological compromise, or a normal state that does not denote any specific condition. Therefore, constricted and responsive pupils are indeed characteristic of mitotic pupils.
