To a pouch that size... Well, since it wasn't specified what kind of environment this PSK should be designed for, I'll assume it's about the same as in here. Also, it wasn't specified how long one should be able to survive with the contents of this pouch, so let's assume that this is your average "hiker-lost" -PSK, so 3-7 days.
In Finland, even in summertime, I would say the first priority is shelter. So, I would add a disposable rain poncho, or a plastic trash bag, just to keep you dry and protected from the wind. Also, a space blanket might fit. Fire, of course, would be a necessity, so add a magnesium block or similar. Paracord is usefull also.
Signaling would be my second priority. Fire can be used, but I would add a whistle. After spending a few nights in the woods without proper equipment, one might find that yelling is not that easy. Space blanket can be used for signaling also.
A button-size compass wouldn't take much space, and that could get you out. Or, if you have no idea where the closest signs of civilization are, at least you can maintain a straight course. Most lost people end up walking in circles.
A knife, if you need to add one here. I'd propably loose my PSK pouch before my neck knife, so I don't have one in my PSK. But, to a pouch that size, find a flat and light little knife. A folder might be a good idea, as long as you know the limitations. For example, a CRKT Side Hawg might fit.
For First Aid, in here I carry an emergency gauze and a snake bite kit... so, think what you might need in your area. Sure, even the smallest wounds can be infected, so if there's space left, add some antiseptic. If its flammable, you can use it to start a fire also (if you really need to). As for bandaids and such: I dont personally have them in my PSK. Sure, I usually have a FAK with me also, but I dont consider bandaids etc. to be survival equipment. Smaller wounds wont be infected in this environment during the few days this pouch is designed for. However, if you feel the need to, pack 'em. If you wanna go light, carry a bandana and a flat roll of duct tape. You can improvise out of them all sorts of gauzes and band aids. Duct tape is usefull in so many ways, that one should carry at least a small amount of that stuff anyway.
Water... for a small, light weight bag, carry a condom or two, or a zip lock plastic bag, with a few purification tablets. Means to boil water would be ideal, but there's no way to carry a metal cup in that pouch. Sure, if all else fails, you can make a "boiling pit" from the space blanket or thrash bags, and boil the water with some heated rocks... Anyway, with the means to purify a couple of litres of water easily, without consuming too much energy, you can increase your chances of survival significantly.
And then the obvious stuff: always tell someone where you're going, check the weather report, and read this forum for all the cool tricks and tips you need!
