What Is a Squeeze- Padi Section 1 Quiz

[jrv331]

Im going over my OWD manual for the upcoming final quiz. While lookingover the chapter 1-4 quizzes I came upon something that has me confused. On the chapter 1 quiz, question 6 it asks what a squeeze is. I thought it was outside presasure exerting force inside(simplified). According to the padi answer sheet its the other way around. According to them the answer is B

6. Circle the letter of the best definition for a squeeze.
a. A condition that causes pain and discomfort when the pressure outside an air space
of your body is less than the pressure inside an air space.
b. A condition that causes pain and discomfort when the pressure inside an air space
of your body is less than the pressure outside an air space.

Sorry if I violated any rules by typing the question
Thanks

Squeezes occur on descent. Pressure outside increases. Pressure inside remains constant (unless equalised).

That fits B.

I think you are just misreading the answers. You seem to have the idea right.

a. A condition that causes pain and discomfort when the pressure outside an air space
of your body is less than the pressure inside an air space. Pambient < Pinternal
b. A condition that causes pain and discomfort when the pressure inside an air space
of your body is less than the pressure outside an air space. Pambient > Pinternal

When Pambient is greater than Pinternal, you have a squeeze.

Ok, now I see where Im confused. According to the OWD manual a squeeze is when the pressure outside exceeds the pressure inside. The answers are worded differently than I expected. B is actually more pressure outside, A is a reverse squeeze(block), more pressure inside.

Guess Im gonna have to read the test questions very carefully, looks like they mix the working up a little.

Thanks for the help

Ok, now I see where Im confused.... The answers are worded differently than I expected.

Welcome to the wonderful world of PADI

Yes, you've got to be careful... PADI have a tenancy to test your ability to comprehend questions, rather than comprehend knowledge.

Don't worry. Once you get through your book work and into the water, you'll KNOW what a squeeze is.

And hopefully you'll only have a book-knowledge understanding of a reverse squeeze. They're really not fun.

My recent experiences with my first drysuit have really "redefined" squeeze for me

Yeah. And not just on the OW test. I often wonder if they do that on purpose or is it just an inability to be clear? The only important thing is that you know the stuff. There can't be any reason for them to just try to trick you.

As someone who deals with assessment as part of his vocation, I assure you that the PADI questions and answers are far better than most I have seen.

I have taken some exams from other agencies, exams that have been in use for quite some time, and found some of the "correct" answers to be flat out wrong. In one case, the instructor had always given his students the official answer sheet when they were done so they could learn from them. When I challenged a couple of the answers, he examined them, agreed that I was right, and said no student had ever challenged them before, so it was the first time he had realized the official answers were wrong.

On another exam I took, students were to work through a series of problems given certain parameters, and within the parameters of two of them there was no correct solution (and no, it was not their intent to trick you). In that case, the agency had already been told that their official answers were wrong, but they had not had changed them yet.

I mentioned that to my instructor when I got certified. As a teacher, if I were to write assessments as poorly as the PADI test authors, I'd be fired. Many questions seem not to test the knowledge of diving as they do the knowledge of how to manipulate the English language!
