For the needles and sutures, etc, if she is traveling with friends, they NEED to know about this stuff, why, and where it is. If she's unconscious, she can't tell the medical personnel anything.

Treating water: she could probably explain it away as allergy to something, or medication, couldn't she?

She needs to know how to contact the American Consulate, not just the other way around.

I wouldn't want to be wearing open-toed shoes or sandals.
