A client is scheduled to have a percutaneous transluminal coronary angioplasty (PTCA) to treat coronary artery disease. What information about the balloon-tipped catheter would the nurse plan to include when providing client education concerning the procedure?

A mesh-like device within the catheter will be inflated causing it to spring open.

The catheter will be positioned in a coronary artery to take pressure measurements in the vessel.

The catheter will be used to compress the plaque against the coronary blood vessel wall.

The catheter will cut away the plaque from the coronary vessel wall using an embedded blade.
