Here's my reply to your comments:
If there were fifty different medications on the shelf, then a few seconds of reading the label would
prevent this medication error. And the staff person knows that they are responsible for knowing what
they are administering (not what they guess they are administering).
But, as I consider many kinds of errors - some are carelessness, some are associated with being very
busy perhaps, so how is the staff person to prevent these kinds of errors, to avoid these errors, to be
treated once they have made an error? Many people make errors - so do we view them as forever
to be condemned for their error, or do we find ways to help them improve (so does it matter if the
consequences were serious or not serious? Because - human beings make errors). We can aim for
perfection - but will it ever happen? Yet, some errors can be prevented, especially when containers
are labelled.
