Before a cardiac catheterization or PCI, what is an appropriate nursing action regarding the insertion site?

• A. Administer diuretics
• B. Start antibiotics
• C. Mark pulse points distal to insertion site
• D. Remove jewelry

Answer: (C)

Marking distal pulse points on the extremity used for arterial access is a key step because it establishes a baseline for perfusion that can be compared after the catheterization or PCI. After vascular access, there’s a risk of reduced blood flow from arterial injury, spasm, a hematoma, or thrombosis, so having a clearly noted pulse distal to the insertion site helps the nurse detect any decline quickly and intervene promptly to prevent limb ischemia. While ensuring the limb is free of constricting jewelry and other general pre-procedure checks are important, they don’t directly provide the ongoing perfusion reference that marking distal pulses does, which is why this action is the most appropriate regarding the insertion site.
