The medical symbol of the staff with the snake is only supposed to have 1 (one) snake on it. A staff with 1 snake is the Rod of Asclepius (the son of Apollo and Greek demigod of medicine), a staff with 2 snakes is a Caduceus which is carried by Hermes as a messenger or herald.
Physicians get 1 snake. Couriers and heralds get 2 snakes. Any medical professional or organization that uses 2 snakes is wrong and needs to go study the humanities and classics for a bit.
Stories like this make me very glad that I got my pediatric experience in a good children's hospital before starting medical school. The attending physicians made sure to drill it into everyone's heads that if the parent is expressing concern about a change in condition or "something just not being right", you report that to the patient's physician and nurse ASAP. Everyone from the physicians down to the admin folks were empowered to challenge decisions they thought weren't in the patient's best interest.
Hell, I even had a case where, as the ER tech, I challenged a physician on her diagnosis of a child and refused to let her discharge the kiddo without looking at him again. The mom told me something was wrong, and even with just an EMT license, I was able to see something was subtly wrong as well. It turns out the mom and I were right and the physician changed her diagnosis and admitted him to the hospital for treatment instead of discharging him home to follow up in clinic in a couple days.
