How do you use a catheter?

Answer:
A catheter is a term used for any thin tube inserted into the body - not just a urinary catheter.
So, you would use a catheter as intended.

You would insert a urinary catheter and secure it by inflating the balloon.

You would insert a central line catheter and x-ray it before use, then use it to administer medications.

Etc...
