H1n1 was the cause of death of my mom :( can we sue?

my sister came home sick from school on october of last year the last week to be exact it was a monday anywho we took her to the hospital that same day because we were afraid it might be the h1n1 and the doctor at kaiser only asked some questions about her symptoms and took a look at her throat and said it was the h1n1 i asked him if he wasnt supposed to do some type of culture to determine that and he said no because it was way more possible to be h1n1 ?? so stupid anywho he said to give her tylenol and i asked him if he would give her some type of antibiotic and he said no tylenol was enough and to keep her well hydrated well my mom woke up sick the next day then me the following day my mom got an appointment at the kaiser clinic on thursday her doctor refused to see her because she had too many patients that day so she was seen by the head nurse or something like that and she just listened to her chest and lungs with the stethoscope and said she had wheezing and her chest was very congested she diagnosed her with bronchitis so she gave her a breathing treatment that lasted 20 minutes then she prescribed her ALBUTEROL a breathing treatment and amoxicillin she said "with this she should get better if she gets worse that's not good" , that was it but they made her wear a mask to cover her mouth and nose.On monday she went to the clinic again now with her doctor but when we got there she seemed kinda agitated her doctor took forever to see her when she finally did the doctor touched my mom she told her that she was extremely cold she decided to do an EKG and sent her to the lab to get some blood work done and some Xrays then they told me to take her to another room because i even had her in a wheelchair because she would get agitated the nurse in there cfhecked her blood pressure and saw that it was very low and called my moms doctor so she came down and told me that they would have to call the paramedics because her blood pressure was extremely low they took her to the nearest hospital then supossedly they would trasport her to the kaiser hospital so i called my dad and sister they were the ones who stayed overnight they told me that they even had to put breathing tube down her throat because she couldnt breathe well later like at 10 am tuesday they went home to shower when my dad went back like at 12:00 am they told him that she had gotten worse that her heart had stopped and that they were trying to revive her my dad was in shock they told that they tried their best but nothing could be done . we waited 3 months to know the real cause of her death they called from the coroners office and they said it was the h1n1 that she suffered a septic shock which caused her blood pressure to drop they said the cause was "death caused due to complications of vital pneumonia " now my question is why didnt the when we first took my sister to the hospital give us specific precautions or something i mean thats what they're trained for something big like the h1n1 not only have i thought we should sue but many people have told us the same thing that we should sue Kaiser Permanente for medical negligence or malpractice because why did the nurse say it was bronchitis when it was the h1h1 she had maybe she could've still have been here :/ ....do you think it's possible we might have a strong case? here we dont want money we just want those doctors their es fired and get they're license taken away for their stupid error.
