NAVTA Practice Test

Before completing a contrast study of any type, you would need to make sure ____.

1. The animal has been fed.

2. There are no other animals in the room.

3. A survey film was taken to see what the animal looks like before given contrast medium.

4. The temperature in the room is comfortable.

The correct answer is: A survey film was taken to see what the animal looks like before given contrast medium.

The correct answer highlights the importance of conducting a survey film prior to administering contrast medium. A survey film serves as a baseline image of the animal’s anatomy and can provide critical information about any pre-existing conditions or abnormalities. This baseline is essential to accurately assess the changes that occur once the contrast medium is introduced, enabling a comparison that aids in diagnosis. Additionally, it ensures that any significant variations in the contrast study can be attributed to the administered medium rather than pre-existing issues that may not have been noted otherwise. While the other options may seem relevant to the overall care of the animal or the success of the procedure, they do not directly address the necessity of having a clear reference point to visually assess the impact of the contrast medium used in the study.
