No. Not possible. An IV bag contains 100mls of saline. You can’t be wearing a suit jacket. There is tubing from the bag with a penetrating flexible plastic needle like tip that has to be inserted into a vein and you have to be laying down.
“They may have lengthened Joe’s tubing for a last-minute detachment without having to remove his blazer?”
That was exactly my thought. To take off the jacket and roll the sleeve up, it could take too long or be inconvenient.
I’ve been hospitalized many times. Almost every time, I’ve had lines put in my wrists because bending the elbow could make it uncomfortable, especially if you’re getting dressed regularly or in generally good enough condition to move around. It makes it easier to put your arm through a sleeve.
To write this off because of placement is absurd.
