Which should be gloved first in putting sterile gloves?

It should really be up to the nurse themselves. I was taught to put my glove on the dominant hand first.

The non dominant hand

Gloves are put on the non dominant hands first and then, the dominant hand. The rationale is simply because humans tend to use the dominant hand first before the non dominant hand. Out of 10 humans that will put on their sterile gloves, 8 of them will put the gloves on their non dominant hands first.
