Continuity mistake: Early in the show, Mark is going into an office to meet with Morgenstern and another doctor. As he opens the door in the hall, his bag is slung over his right shoulder, but when the shot changes and he's entering the office, it's over his left shoulder. He had no time to change it.
Status Quo - S14-E11
Continuity mistake: Sam's hand instantly changes position after a camera cut, from her chest to on her hip. This is at the start when she says, "Shower sleep - that's more my style." (00:04:00)
Continuity mistake: When Carol is talking to Angie in the hospital, there is quite a large bloodstain on Carol's sweater, just below her left shoulder. She leaves the room, meets Doug, and without explanation, the bloodstain has disappeared.
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: 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: After saving Mr. Perez, Carter says "That's a nice save" to Mark, and takes his stethoscope out of his ears and wraps it around his neck. The next shot, however, from behind him, shows the stethoscope is still in his ears.
Continuity mistake: Mark is showing Lucy around the hospital and they go from an examination room to a trauma room - as they go through the doors, Mark is in front and pushes open the right door and we see it stays open. Lucy never touches it. But the shot showing them coming into the room has Mark letting go of the door and it swinging shut.
Obstruction of Justice - S4-E9
Continuity mistake: When Jeanie is in the office with Kerry, Anspaugh, and the union rep discussing her firing, her stethoscope changes position over her name tag several times within a few seconds.
Continuity mistake: Near the start of the show, Peter is holding baby Reese upright when he opens the door to Carla's room, but as the shot changes to show him coming through the door, suddenly the baby is lying horizontally in his arms.
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.
Continuity mistake: Susan goes to see the patient Mrs. Garvey - we can see the sticky tape on her right shoulder, but as the scene progresses, her gown is pulled up, covering it - even though no one adjusted it during the scene.
Continuity mistake: Harper is talking to Mark about her night with Doug and her stethoscope is hidden in her collar and lapel on her right. As the shot changes and she turns, it is suddenly fully visible and the left side has moved much further up towards her neck.
Do One, Teach One, Kill One - S2-E3
Continuity mistake: As Chloe moves backward away from the fence while talking to Susan, we can see her friend Ruth in the convertible, sitting up on the back of the seat. In one shot Ruth completely disappears but reappears again, all in the course of a few seconds.
Revealing mistake: As Carter walks into the baby's hospital room to see why it is "crashing." In the long shots the baby is obviously a doll, and its mouth is closed even though it is crying.
Nobody Doesn't Like Amanda Lee - S5-E11
Continuity mistake: When Chuni gives Peter, Gwen's chart, there is a narrow strip of paper over the other sheets. But when he goes into the girl's room, that strip of paper disappears.
Continuity mistake: When Anna and Max are talking in the lounge, a piece of her hair is hanging over her ear when the shot is from behind her shoulder, but from the front angle, it's tucked smoothly behind her ear.
Continuity mistake: Carter and Lucy are standing in the middle of the admitting, where they are talking about a case. Lucy asks, "Does it resemble a Christmas tree?" and Carter's stethoscope goes from being visible over his lapel to being tucked under it.
Revealing mistake: Just before the bowl of pablum falls onto Peter's head, look carefully to see a white adult hand (looks female) holding baby Reese's spoon, and push the bowl so it flips over onto the actor's head.
It's Not Easy Being Greene - S2-E13

Continuity mistake: Susan comes home carrying bags of groceries. When she first sees Chloe sitting at the door, a box of Kix cereal is on the side of the bag next to her body, but as she says "Chloe", the box is on the other side of the bag, away from her.
