Other mistake: When the doctor left Sharyn's room, the hallway behind him appeared to be relatively short and no doors to other rooms could be seen, but when Sharyn looked out the room, there were numerous doors/rooms on each side down a long hallway. (00:05:00 - 00:05:47)
Other mistake: Sharyn was hooked up to an IV catheter somewhere in her upper arm (underneath her gown's short sleeve). The IV's location is unusual because IV catheters are usually placed in an easily accessible location, such as the back of the hand or forearm. When Sharyn ran out of her room, she apparently ripped out the IV without injuring the injection site or causing any bleeding. After being returned to her room from her escape attempt, she no longer required IV therapy (wasn't hooked up). (00:06:30 - 00:07:34)
