Which of the following is considered an invasive procedure?

Invasive procedures involve entering the body by breaching the skin or penetrating a body cavity, vessel, or organ. Catheterization fits this because it requires inserting a catheter through the skin into a blood vessel or other interior space, which typically involves sterile technique and can involve tissue puncture. That entry into the interior of the body is what makes it invasive. The other options do not breach the skin or enter internal spaces. Ultrasound uses external sound waves to create images and does not insert anything into the body. X-ray imaging is performed with equipment outside the body and does not require penetration, unless a separate invasive step like injecting contrast is performed, which is beyond the basic X-ray itself. An EKG records electrical activity with skin electrodes and likewise does not invade the body. So, the procedure that is invasive among these is catheterization.
