BLUE TONGUE SKINKS

My skink had her very first snail today. She knew exactly what to do with it. She slurped it right up and looked at me for more.
My question is- it was a pond snail that came from one of my tanks (I have a huge surplus) and it was fairly small so she swallowed it whole. Can she become impacted from swallowing them whole? I doubt it because if it were big she would have crunched down on the shell and she would have been able to digest the pieces.
Is it dangerous to feed her smaller snails that she swallows whole?

they are too small to get stuck. impaction wont happen from aquarium snails. Ive fed my blueys those heaps of times as long as the tank water quality is good, no chemicals or illness running through the tank etc
