Continuity mistake: When Peter and Jeanie are outside talking about their test results, there is an extra in a green sweater behind them who covers more ground than humanly possible from one shot to the next.
Continuity mistake: When Peter goes to his sister's picnic, he puts a pink box on the table and then sits in front of it. When his attention is diverted by a woman, suddenly the box is in front of him.
Continuity mistake: Carter is doing a nasogastric intubation on a emergency patient and suddenly the patient violently pukes blood all over Carter's medical gown, his throat and the lower part of the face, then a quick shot of the stunned nurses, and when Carter is shown again he is perfectly clean.
Continuity mistake: Carol is at her house with her mother, who makes 2 cups of coffee. She brings them to the table and Carol takes one but in the next shot, both mugs are still sitting on the table in the original position.
Continuity mistake: When Jeanie is meeting with her doctor, the doc fills a mug with coffee and puts in on her desk. The mug does a 180-degree turn so that the handle is facing the opposite direction. Another shot - and it's back to the first position.
Continuity mistake: Carters throws his white towel on top of the lockers and it falls to the floor and the locker door closes - but the next shot shows the towel on top of the lockers again and the locker is half-open.
Continuity mistake: During the scene where Carol and Mark are arguing with Doug about him examining the girl, the door behind her is closed. At the end of the scene, as Doug walks away, the door is open, even though no one went near it.
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.
Continuity mistake: Mark is watching Susan get on the helicopter and he hooks his Flight Physician jacket over his finger so it is hanging over his shoulder completely down his back. However, the shot from behind shows the jacket partially draped over his left shoulder - then it goes back to being down his back.
Character mistake: When Dr. Keaton rushes back into the OR to take over from Peter, she moves forward, pushing the door open with her hands. No surgeon would EVER enter an OR this way-it would contaminate her hands. The proper way is to back into the room, keeping one's hands in the air and free.
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.

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.
Homeless for the Holidays - S3-E10
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.
Homeless for the Holidays - S3-E10
Character mistake: When Doug leaves work, he tells Carol he is Going Home to watch the channel 11 Yule log. Later on, he shows up at her house with Charlie and Carol says, "I thought you were watching the channel 9 Yule log." It's possibly a slip of the tongue from Carol, but most likely it would be ingrained in their heads which local channel features a Yule log at Christmas.
Night Shift - S3-E11
Continuity mistake: When Carter and Doyle are running down a corridor to the patient having a heart attack, the camera follows them along the floor and you can see several coloured lines going down the hall. After we see this, they burst through a double door, and if you look behind them you cannot see these lines anymore; they've simply vanished.
Post Mortem - S3-E12
Continuity mistake: When he's scuffling with the homeless man in the trauma room, Carter's stethoscope slips off his shoulders and drops to the floor. By the time Mark finds him standing outside, it's back around his neck, with no moment when he could have picked it up.
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: 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.
Continuity mistake: Carter is watching the clock, waiting for Peter to show up for a presentation. The clock jumps from 3:03 to 3:04 in a Split Second (we literally see the minute hand jump)but the second hand doesn't change posiiton.
Answer: Take care of your dad.
