This is one of a few places you can exploit the game's placement of items. In mission 3, you are tasked to restart the Ishimura's engines. On your way to the engine room, there is a node locked door next to a set of malfunctioning, fast shutting doors.
Do not take items from the node locked room, but unlock the door and use the kinesis module to move the items (money, medikit, schematics, ammo) out of the secret room and leave them anywhere on the ground.
Use stasis to bypass the fast-closing doors and go to the end of the hallway to a save point outside the engine room. You do not need to save, just touch the save point. This gets you far enough from the node locked room to duplicate the items.
Travel back to the node locked room (past the fast closing doors) and some of the items in the secret room will be there, as well as the ones you used kinesis to move out last time.
This exploit stops working if you take any of the items (i.e., if you take the medikit, the medikit stops respawning) or when there are too many items on the screen (about 30 or so). If you need more stasis to get by the door, use the "Restore Stasis Energy" code seen on this page.
This exploit works elsewhere in Dead Space where you have preset items and can move far enough away to silent-stream in a new area or map.

Conserving ammunition is vital as you get deeper into the ship. The old exploit from Resident Evil 4 works with the weapons here too. When you are out of ammo and have a Bench and several Power Nodes, you can refill the ammunition in the weapon to its new maximum by upgrading to a capacity node in that weapon.
