Synopsis by Hal Erickson
April Fool's Day brings a combination of the silly and the serious to the ER, with emphasis on the latter. A police officer shoots an elderly patient with dementia, but full blame for the incident may actually rest with two of the ER staffers. Several teenagers are injured while trying to "huff" carpet cleaner. A pregnant teenager treated by Kovac (Goran Visnjic) suffers complications in more ways than one. Corday (Alex Kingston) faces another career crisis. And on the lighter side, Carter (Noah Wyle) tries to brush off Rena (Lourdes Benedicto) by telling a fib that may spell trouble for one of his colleagues.
