Critical thinking as a new RN

[Lpn to RN]

I recently started a job working in a hospital (will be off orientation in two shifts). And I feel like I'm lacking on critical thinking/judgement skills.

Back story: As a LPN, I worked for a little over a year on the same unit I am now. But 3 years ago, I left the hospital for school nursing. As a LPN in the hospital, my critical thinking/judgement skills were sharp (I had previously been in a RN program) and I frequently had staff request for me to stay on the unit rather then float and then them get a less experienced RN float/travel nurse. 

But when I left for school nursing, I didn't need those skills as much. Don't get me wrong, we do use critical thinking skills in school nursing but just not in the same way.

During my RN schooling (this time around), I voiced concern to my instructors about not being able to get my brain back into critical thinking. They all told me "don't worry, it will click.” 

Now I know I'm still on orientation but I feel like I should be further in the critical thinking/judgement skills than I am. 

Suggestions?
