For my wifes kit, knowing her lack of training, I gave her the following
1. TQ
1. 4x6 pressure dress.
1. Big abdominal dress.
1. Roll of gauze
1. Compressed gauze
1. Z Fold Quick clot
1. Foil emergency blanket
1. Sharpie
Pretty much I intend to gear it toward the incident she came upon and if she can understand how to deal with an extremity amputation she can likely do no harm with other injuries.
TQ the limb, Sharpie the time, Pack with Quick clot/gauze, apply pressure dressing, further protect with large abdominal gauze, treat for shock by maintaining heat, elevate wound, monitor for bleed through, pressure on artery to bone, you have done all that can be expected.
