Execute a shell script in current shell with sudo permission

Question

For executing a shell script in current shell, we need to use a period . or a source command. But why does it not work with a sudo permission?

I have a script with execute permission called setup.sh. When I use a period, I get this:

$ sudo . ./setup.sh  sudo: .: command not found 

The source command also produces a similar error. Am I missing out something? What should I do to run the script with sudo permission in the same/current shell?

Thanks in advance..

I'm not sure if this breaks any rules but

sudo bash script.sh 

seems to work for me.
