[quote=mattsmom81]The article contradicts itself. First it says an angry patient runs down 2 nurses. Then later it states investigators aren't sure the nurses were targetted. HUH??[quote]
I think they meant they weren't sure if those two particular nurses were targeted. Sure, they were targeted...because they were in the driver's line of sight...but probably not because she had a personal vendetta against those two individuals. (Does that make sense at all?

)
As to the driver being 'drug seeking'...this is quoted from the local NBC affiliate:
The driver was angered because a doctor at the hospital refused to prescribe her a certain type of drug, according to sources at the hospital.
