CRCST Practice Exam

Which of the following will occur if Ultrasonic bath temperature is too high?

1. It will lead to increased cleaning efficiency

2. It will cause instrument discoloration

3. It will lead to protein coagulation

4. It will enhance rust removal

The correct answer is: It will lead to protein coagulation

If the ultrasonic bath temperature is too high, it will lead to protein coagulation. This is because high temperatures can cause the proteins to denature and clump together, making it more difficult for them to be dissolved and carried away by the cleaning solution. This can result in a less effective cleaning process and possibly even damage to sensitive instruments. Option A is incorrect because high temperature does not increase cleaning efficiency, rather, it can have the opposite effect as described above. Option B is incorrect because discoloration is typically caused by other factors such as the cleaning solution or material of the instrument. Option D is incorrect because while high temperature can enhance rust removal, it may also cause damage to the instrument being cleaned.
