Another question which you ca reference the constants listed at the top of every PADI physics exam. It states that every metre sea water the pressure increase is 0.1 ATM.

So the first part of the equation should be depth (35) multiplied by pressure (0.1). The answer should be in absolute pressure so we need to add the additional 1ATM that we start at from the surface. 35 x 0.1 + 1 =

The three general terms of heat transmission that PADI lists as affecting a diver are conduction, convection and radiation.

The Valsalva Maneuver has many applications and benefits when used correctly. When misused due to a prolonged or forceful application it can have several drawbacks also.

PADI always list the issue they consider primary to divers being the rupture of The Round Window but there can be more adverse effects. 

If you ever see a diver attempting forceful Valsalva address the issue and help them work on their equilisation technique or underlying issues that may be causing them to feel they need to forcefully equalise.

You have noticed that in the modern text it's referred to as Gas Narcosis rather than Nitrogen Narcosis. 

All gases will become narcotic at some point when breathed under pressure and one of the symptoms can be displaying foolish behavior amongst other things.
