cardiac cath lab question re sheath/wires/catheters


Hi All! I am new to cardiac cath and have a question regarding the order of things during a procedure. Correct me if I am wrong: First a sheath goes in, then a wire is inserted as a guide for the catheter. Then the physician can place a balloon or stent?? Is that the right order of things during a cardiac catheterization?

Thank you very much everyone! Appreciate any other advice for a new cardiac cath RN, especially anything online (preferably free) that I could study up on.

Stay Safe Everyone.
