Ben refers to the puppy as a male but in the previous episode, Dr. Lewis refers to it as a female.
Sam declares the girl with cancer dead. A nurse cannot do that.
When Dr. Kovac does the x-ray on Alex's head he tells him to hold his breath. That would be totally unnecessary since holding his breath would have no effect on his head position.
After Dr. Romano does the rectal exam on the prison inmate he gets up and opens the door without covering the patient for comfort and privacy. It is a major state health violation for the health care team to leave the patient open to be seen by the public in any state of undress. Only time it would have ever been somewhat accepted is during trauma when the patient needs outweigh patient privacy issues.
@24 min Dr. Gallant and Sam were at the "Doc in a Box", small clinic not equipped to handle ped's patients and Dr. Gallant asked for ox and Gent (meaning gentamicin) but he should have asked for Vanc (Vancomycin) and Gent as these are both antibiotics that cover a broad range of infections. Ox is oxygen and they already asked for that.
