No such thing as a dumb question... most new nurses will hear that. But I say, they do exist.
In this case, this isn't about lack of nursing experience or perhaps the OP is still not in a nursing program, but still!
Let me break this question down.
Ok, so long nails and gloves and Peds. Let's drop the gloves part since that's very obvious.
OP, imagine working with these little babies/toddlers with your long nails, I think even a non-nursing person can figure that out.
I, truly, sometimes wonder if we really ever landed on the moon!
Pressed nail... what the hey is that anyway?
