The writers show that the mother is unable to bring toothpicks in for a dish she is bringing to Adam. The room Adam is in, however, has clearly exposed electrical sockets and even an easily breakable ceramic lamp, none of which would be located in the room of someone on suicide watch. Patients generally are kept from electrocuting themselves or cutting themselves on broken glass.
