I guess if she says it does, I dunno yeah maybe. I have too many doubts to try it though...
Ask for a couple pair next time you see her and give it a try, nurses have access to thousands of those things, they're everywhere for employees to get quick access (exam rooms, supply closets, front desk, nurse stations, etc)....
I'd ask her what gloves she wears over them to keep warm hands, it may be the outer riding gear gloves doing the actual job. And what knd of rides does she do (short commutes or pleasure long rides -how long?, etc.)
I wore latex exam gloves at work for almost 5 years, when I worked at a lab supplier for medial and industrial firms. I just never remember them being a thermal insulator while in the labs. They do not breathe that's fer sure, and your hands can sweat in warm conditions while you work due to not being breathable (like a PVC raincoat does). The only thing I see wrong with the theory is that riding glove liners need to wick moisture away from your hands to keep them warm. If you collect sweat inside the liners from sitting in a traffic jam, then openup to 30 miles on the open road, it can't be cmfortable with cold sweat surounding your hands doing 70-80mph.
Give it a try.. Who knows, maybe it does work...
I've always used glove liners.
Silk liners ($9) with vented Leather gloves in the summer, and Polar Fleece ($16) with unvented leather gloves for the cold months.
Both the silk and fleece are breathable, so they do wick moisture away from the hands.

P.S. I just saw Brian's post.. He thought the same thing on moisture. A puffy swollen face and difficulty breathing is a typical severe allergic reaction people have who are allergic to latex. But, you have to be allergic to it, to happen... I worked with a new employee in an industrial lab that was allergic to latex. The lab required a latex hood, breathing mask, goggles, and Nitrile goves (chemical resistant). She put on the hood, was itching shortly thereafter... A little later she couldn't stand it and pulled the hood off-->man! she looked like she stuck her face in a hornet's nest and was sent to the emergency room immediately before it escalated into shock... Bad stuff, but ou have to have the allergy, people not allergic won't have a reaction (unless its chafing or a irritation rash)...
