Certified Playground Safety Inspector (CPSI) Practice Exam

What is the thickness and minimum insertion depth for a torso probe?

1. 3" and 3.5"

2. 3.5" and 4"

3. 4" and 4.5"

4. 4.5" and 5"

The correct answer is: 3.5" and 4"

The correct answer is B because the thickness and minimum insertion depth for a torso probe is generally around 3.5" and 4" respectively. Option A may seem like a close answer, but 3" is too thin for the torso probe to be effective. Similarly, options C and D are incorrect because their thickness and insertion depth exceed the generally accepted range. Choosing them would result in a thicker and longer torso probe than necessary, potentially causing discomfort for the patient. Therefore, B is the most appropriate answer.
