“There is a huge difference between drawing blood for medical purposes and drawing blood for legal, evidentiary purposes.”
From the article: “She told the officer a patient was required to give consent for a blood sample...”
So the article is Not saying what you said above and I reacted to the article.
Is what the article attributed to the nurse wrong?
No, the article was right and the nurse was right. She was talking about a blood sample to be used for legal/evidentiary purposes.
A blood sample, for those purposes, requires either patient consent, a warrant, or that the patient be under arrest.
A blood sample drawn for purposes of providing emergency medical care to a patient does not have those same requirements.
It's a pretty easy difference to understand.
