Character mistake: The girl who admits to changing Chase's profile says that what she is doing is negative reinforcement when it is actually positive punishment. Negative reinforcement involves taking something away (eg a noise) to encourage the behaviour whereas positive punishment involves adding something (the pictures) to discourage future behaviour.
Dying Changes Everything - S5-E1
Continuity mistake: Right at the end, when House is apologizing to Wilson, watch the bright spot on the TV frame on the wall behind House. In the long shots, the spot is right at the top left corner of the TV. In the close-up shots, the spot is closer to the middle. This is visible every time the shot changes from long to close-up. Light spots do not move depending on the position if the viewer. The only way a light spot changes is if the light source changes position or the reflecting surface changes position (try reflecting a flashlight beam off a mirror and then, leaving the flashlight and the mirror alone, move around. The reflected spot of light will not change position).
Other mistake: House and Wilson are in the Mens room, and there is a tampon/sanitary pad dispenser. (00:21:30)
Emancipation - S5-E8
Continuity mistake: At the very beginning, House walks in and puts his cane on the table on top of Thirteen's papers. She picks it up and moves it away, placing the bottom end on a stack of books. Cut to House and the cane is now flat on the table. (00:02:55)
Merry Little Christmas - S3-E10
Other mistake: Just by looking at Abigail's mother, it is obvious that she does not have cartilage hair hypoplasia (Meredith Eaton has pseudoachondroplasia).
Factual error: In an episode with a severely overweight patient who is thought to have diabetes, it is discovered he instead has Chagas disease. Cameron then informs the patient that he acquired this illness from his food when, in fact, Chagas disease is a protozoan that is spread through the bite of the triatomine bug.
Suggested correction: While the main vector for the infection is through the triatomine bug, Trypanosoma cruzi (the parasitic organism that causes the disease) can be transmitted through food, and thus Chagas was caused by the food the patient ate. It should also be noted that Trypanosoma cruzi is not transmitted by the bite of the triatomine bug, but rather through its feces, and it's only spreads once the feces enters the blood stream (which it can do through a bite site or scratching an open wound).
Character mistake: House says to Chase "I've got a dead baby for you to biopsy." A biopsy is a test performed on tissue from a living patient. He should have said 'autopsy' - the procedure performed on a dead person to determine how they died. House, as a doctor, would know this distinction. (00:32:45)
Continuity mistake: When Wilson and the team are walking and stop in front of Fran's room, you can see Robin lounging in a chair in the background. In the next shot, Robin is gone.
Continuity mistake: The runaway has an attack when her mother shows up and coughs blood on the table. There is an emesis basin at the far end of the table she throws up on. The shot changes twice and now there is FAR more blood on the table and the basin has moved to the middle of the table. Before the first shot change, Taub is reaching for the basin, however, after the change he is moving away without enough time to move the basin. The shot changes again and the patient is now in the bed with Adams holding the basin under her mouth. There is not enough time in that shot change for her to move from the foot of the bed to in the bed.
Other mistake: At the end, before House's "realisation" the camera pans out and shows a street light when House and Wilson are outside talking. The lamp top is covered with fresh snow. It's been dark for sometime. The heat from the bulb would have melted snow had it actually been real.
Other mistake: When House is inserting foil pieces in the wall socket to create a short circuit in order to ignite a roll of toilet paper, he touches both pieces of foil simultaneously, which should have electrocuted him. (00:30:30)
Factual error: When Dr. Cameron's agoraphobic patient goes into cardiac arrest at home following the surgery, she tells House to get the paddles ready. House, while performing CPR is talking on the phone with the patient's lawyer, informing him that patient has PEA (pulseless electrical activity) on the cardiac monitor, but Dr. Cameron defibrillates the patient anyway, restoring the heartbeat. Defibrillation is not indicated for PEA, it will not restore the pulse and might send the patient into vFib.
Character mistake: Dates on a former patient's file indicate a birthdate of 04/24/24 and an admission date of 02/04/94 (an attained age of 69 yrs 9 months 11 days); House subsequently refers to that patient as a "73-year-old woman." (00:06:19 - 00:08:37)
Role Model - S1-E17
Continuity mistake: After the whole body scan back in the lab, Dr. Wilson tells the team that the Senator has a slightly enlarged lymph node in his left armpit. When they subsequently go to check the problem, they are working on his right armpit instead of his left.
You Don't Want to Know - S4-E8
Factual error: Amber triggers a fire alarm by heating the sprinkler with her lighter. Unfortunately that fire sprinkler doesn't detect heat (or smoke). The sensor is located between the ceiling lamps, about two meters from the fire sprinkler. (00:09:00)
Suggested correction: Heat applied to the sprinkler would cause it to activate and spray water. All modern fire systems will detect this water pressure drop and activate the alarm.
Factual error: Every time there is a patient given a non-rebreather O2 mask, the bag is uninflated. The correct way of administering O2 through a NRB is to inflate the bag first, which would be the reservoir for the O2; a common mistake in many Hollywood medical shows.
Deliberate mistake: When extubating the patient from the respirator, the patient would have been sedated as to not cause discomfort or pain so they can die peacefully. Furthermore, the ET tube is seen being taken out, but it cuts so the actor can hold it in his mouth without choking, but in real circumstances, it's not nearly long enough to go down the trachea.
Continuity mistake: When House steals Wilson's ice cream, the ice cream gets bitten more than once even though House only takes one bite at it. (00:12:45)
Transplant - S8-E2
Revealing mistake: When Wilson punches House in the face, is it painfully evident that he doesn't connect.
