Helping People

Can I seek protection under Washington's Good Samaritan law after an accident?
I helped a guy who was hit by a motorbike. I offered to drop him at the hospital. On our way, my car’s break suddenly stopped working and we ended up hitting a pole. Luckily, we didn’t get hurt much(we both got a few bruises). But this guy is blaming for his bruises which is absolutely false. Can I claim protection under the Good Samaritan law of Washington?
Can I treat a minor without parental consent in an emergency?
I am a doctor. Recently I went to my child’s sports day. During the event, one student (11 years old) got hurt so I offered to treat this child. Unfortunately, her parents had not arrived when this whole incident happened. I treated this student and gave her some medicines. I have a doubt- can I land in trouble for not taking this parents consent before starting the treatment.
Can we hold a doctor responsible for giving my wife harmful medicine?
My wife fainted while we were walking in the park. A guy who claimed to be a doctor offered help and we went to his house. (His house is very close to this park) he gave my wife some medicines and when she was okay we left his house. His medicines had a bad reaction on my wife’s body and she got some sort of infection. Can we hold this doctor responsible for the same?
Can I sue my colleague for not taking me to the hospital?
I’m a kidney patient. While I was in office, I fainted due to high blood pressure. My colleague took me to the medical room in our building and left me with the nurse over there. This colleague knows about my health and diseases still he did not care to take me to the hospital. Can I sue her for not arranging for further treatment despite knowing about my disease?
Can a case be filed against a school nurse for giving wrong medicine?
My friend fainted while she was at school. The school nurse was called to take care of her. This school nurse gave some medicine to her that reacted and she was rushed to the hospital. Later we got to know that the medicine didn’t suit. Can a case be filed against the school nurse?
