Go ahead and downvote me for this, but the medical field in the US especially when it comes to RNs needs a shake up. This is going to sound very crass, but the only skill that your average person on the street doesn’t have that nurses have is to stick a needle in a vein and that’s something that can be taught to a lay person over a week. Pretty much everything else are skills that any person off the street possesses and we would do well to have a lower bar for entry for it.
