What to do para hindi nginigin ang kamay during retdem?

Currently approaching 2nd sem of 2nd year nursing at isa sa mga ireretdem namin this sem ay ang pagsiskin test. As a student nurse, what can I do para hindi manginig kamay ko especially since I've been known to have shaky hands lalo na pag kinakabahan.

I'm feeling super anxious over this, hindi ko alam paano ito maitatawid because clearly hindi naman basta-basta nawawala yan in just a few months🥲
