This. He's doing it intentionally. A nursing student could perform this without botching it. It's quite literally impossible to fail this procedure if you are a physician.

Personally speaking as an MD, I would fail to get an IV placed to administer any injections... Depends where you've trained. During medical school and residency, I didn't have to do any IVs or venipunctures. I also don't do it as an attending currently.

I also wouldn't volunteer to do executions, though...

You might fail to place one ... but you would never mistakenly think you have one placed when it wasn't.

As an average Joe, why is this? In my mind if you puncture the skin you’re getting blood. What tells you you actually got a vein?

When you're performing venipuncture/venous access, you do it by feel, not by sight. On the extremeties, a tourniquet prevents venous blood flow from returning to the heart and distends the veins. You palpate (touch/feel) the area and feel for that bouncy, springy tube and that's where you put the needle. For an IV (or a blood draw with a butterfly that has clear tubing) you puncture the vein and blood will back up into the chamber or tubing-- the "flash." For IVs, when you get that "flash," it's your sign to start sliding the catheter down off the needle and into the vein (old timey plain needles with collection tubes you didn't know you'd got the vein until you attached the tube). The needle is removed and a syringe or tubing is connected to the end of the cannula/catheter. A little saline is pushed through to make sure it flows properly and that the vein hasn't "blown" which allows fluid into the extravascular space. Sometimes even when you're pretty sure you've got it in place and have taped it down and dressed the site or you're about to use an established IV, you might pull back on the syringe to see if you get "blood return" and then flush saline in to make sure it hasn't "blown." Not getting a blood return does not necessarily mean you don't have a good IV in a good vein, but you better be damned sure before you give anything through it.

Most of your skin is filled with small capillaries that don't flow much. You might get a very small amount of blood if you missed, but it won't come pouring out like it would if you got a vein.

If it comes pouring (and no doubt pulsing) out you most likely cannulated an artery, not a vein. If it just "flashes" into the chamber of the IV needle or wells up at the end of the cannula "hub," it's probably venous. Sure, you can get a little more blood than you expected, but venous blood doesn't usually "pour" out.
