The hand or the arm are specifically cited as where to place the IV for this class of drugs (at least in the material I’ve been able to read).
I mean that’s most IV drugs as it’s the least invasive place to do it. However, for someone trying to obscure their health problems an IV in the hand is crazy.

Same for something like a stroke, or even a slip and fall tbi.
The point is that there are plenty of reasons for an elderly person to have bruising on their hands, but experimental Alzheimer’s treatment is a bit far-fetched.
Yes, bruising is a common side effect of IV inversion…which is why it would be weird to do it on the president’s hand if they were concerned about optics. There are plenty of places you can put an IV.
