I am thinking of employers. This could be an exception, but most employers want their employees to work the hours assigned and not go wandering hither thither without knowing where they went. I can only speak to my own work experience. I have always had a flexible schedule, but it would still be considered odd if I left/ went awol less than an hour into my work time for any reason short of a restroom break or emergency unless cleared with my boss. But maybe this nursing home is different.Don't forget though that she wasn't working your traditional hours. If she's handing over something, it's unlikely to be too far into her shift, like 2am or something, given most people are asleep at that time.
