kitchen drain stub-out picture 1

This is the drainpipe coming out of the brick.

Hi - before you read this I want to warn you that I don't konw the plumbing lingo so please bear with me. I just moved into a 1955 home and discovered that everytime I wash the dishes the water comes out a pipe that extends out the brick in the area of the kitchen sink. This pipe is not PVC - it is metal and looks old, rusted (extends about a fourth of an inch out, is smooth on the outside and has about 1/8" inches of worn out threading on the inside). The Ptrap and trap arm are PVC but it seems like the drain stub out is also metal only newer than the one that extends outside. (I was told the plumbing was redone not too long ago). The water comes out that old metal drainpipe at the same rate that I have the faucet on. I was told that it may be a cleanout and that if I plug it up the water would be redirected to where it should go. I went to home depot and one of the guys there told me that plugging it up might cause the water to backup, not to mention that we couldn't find either a pvc fitting nor a galvanized fitting that was the appropriate size (I believe that was 11/2").

About one foot away old metal pipe in the brick is a plugged pvc (2").

Should I try to plug up the old metal one, if so what can I use - PVC?

Should I try to connect the old metal one to the plugged PVC in the ground?

Should I take out the drain-stub out and replace it with a pvc one?

Should I call a plumber?

I agree that it must just be an old 1.5" galvanized clean-out.
Try to carefully wirebrush the old internal threads clean, and screw in a 1.5" PVC plug with teflon tape flat-wrapped about 2-3 turns around the threads of the plug clockwise only as the bottom of it faces you.
There isn't any real pressure on a drain, so any plug that stays in place should hold it. If the threads don't hold it, just caulk a plug in place to seal it off.
Good luck!
