In health care, there is very little room for sloppiness ("Case of Nurse Charged with Homicide for Medication Error Raises Concerns," https://wp.me/p7sy0l-78i). Everyone, on occasion, becomes just a little bit complacent at work, whether from fatigue, not feeling well, or an unsafe work environment. One can only hope that those occasions are rare and have little consequence. When it comes to medication, there can be no cutting corners.
Unfortunately, no human being is perfect, and no system is perfect, but when it comes to providing health care for another individual, we can try mighty hard to get close.
