Continuity mistake: Abbie is asking Peter and Carter questions about infant developmental stages and they are standing up straight next to the crib. When she says "don't worry, Dr. Benton", the shot shows Peter with one elbow draped over the crib and Carter is leaning over with arms folded. They could not have changed so quickly in real time.
Plot hole: When Mark slips and falls in the staff lounge, he puts both hands on the table to catch himself - but we can see him (the actor) quite deliberately lower his head to one hand - this is supposedly where he cuts himself, but he actually hits his hand and not the table. This would not produce the deep cut he ended up with. Also, the head makes contact on the left of his forehead and he ends up with a cut on the right. And when we actually see the cut, it is vertical and logic tells us that it would have been impossible for him to have a vertical cut from the angle he fell.
Continuity mistake: Nick the dog is standing in the sink and Mark and Doug have got him just about completely covered in soap. The dog jumps out and runs out of the room - by the time he reaches the hall, only a couple of seconds later, the soap has almost completely disappeared.
Continuity mistake: Benton is talking to Carla about her preganancy test and they go through the double doors to the snowy outdoors. Carla has nothing in her hand when she pushes the doors open, but once outside she is holding a hat - she wouldn't have even had time to pull it out of her pocket.
Continuity mistake: When Mrs. Novotny offers to get aspirin, Angie helps her up by Mrs. N.'s left hand - there's no blood on it, but the next shot shows her hand quite covered in dried blood. Mrs. N. has no blood on her clothes, despite being right next to her husband while he bled to death and Carol administered CPR.
Continuity mistake: Carol is working on James' injury and Duncan goes to answer the phone. James has his arm wrapped around the phone but the shot changes to focus on Robert - we can still see James but his arm is now at his waist, even though he had no time to change positions.
Continuity mistake: While Carol is trying to save Mr. Novotny's life, Mrs. Novotny's hair alternates from being loose and hanging over her cheeks to being neatly tucked back into her bun. In fact, a few minutes later when Carol asks for her keys, her hair looks just-brushed shiny and newly coiffed - it's unlikely she would have fussed over her hair at this stressful time.
Revealing mistake: When Mark goes to treat his cut, he leaves the lounge with a couple of tissues held to his head. He gets some supplies and puts a supposedly fresh piece of gauze to his forehead - however the gauze already has some "blood" on it - a feature the camera obviously wasn't supposed to catch. When Jeanie comes over to check it out, he pulls the gauze away from himself and - voila - there's the bloodstain.
Continuity mistake: Dr. Hicks is standing in front of the surgery white board talking to Carter and she says "Care to join me?" He replies "Love to" and the shot goes right back to her - she has moved 8 or 10 inches to the left, without enough time to have done this in real life.
Plot hole: Carol and Duncan escape out the back of the shop - but there are no police waiting for them, which makes no sense at all. In reality, with such a situation, the police would have been waiting at the back door. There seems to be no one around at all, as they were able to dash through an apartment. When they finally do run into a cop, he automatically assumes that Carol is an innocent bystander, and not one of the robbers. He couldn't have known this, and in reality, a policeman wouldn't assume it.
Continuity mistake: In this episode you see Carol and Doug discussing Charlie over phoning and chart-reviewing. Carol is standing beside Doug. Suddenly somebody calls from behind the desk. It's Tommy, a "friend" of Charlie. When he's in the picture, you see Carol sitting in a chair, instead of standing. If she had moved to the chair, she must have done that SO fast, it's impossible.
Continuity mistake: Carter is working on a patient who has swallowed a lot of taffy - he is sitting behind his head with both hands working on his mouth. But when Anspaugh walks in he suddenly has one elbow up in the air and the other hand wrapped around the patient's chin. There was no time for the change in position.
