A good nurse will find vane in arm. Don't let rookie do it. Request skilled nurse. My wife is same with vanes, but skilled can do it.
Do the full scan with the die. Well worth it.
My was 3 of 12 on biopsy. Please be supportive to him. He needs it.
Even after, he will not be able to preform for a while. Be supportive.
Communicate feeling and require him to do same.
Google and read.
Medican has come a Long Long way. He will recover and you WILL have him back almost whole.
Communicate with him. Can't say it enough.
Good Luck.
