After a cardiac catheterization, which finding requires immediate intervention?

• A. Diminished dorsalis pedis pulses in the affected leg
• B. Slight bruising at insertion site
• C. Mild numbness in toes
• D. Slight increase in heart rate

Answer: (C)

After a cardiac catheterization, protecting the limb’s blood flow and sensation is the top priority. A finding that signals a potential and urgent problem is a diminished pulse distal to the catheter site. This suggests the possibility of arterial occlusion or a hematoma pressing on the vessel, and if not addressed promptly, it can lead to limb ischemia. The nurse should immediately reassess neurovascular status (pulses, color, warmth, cap refill, pain, and sensation), notify the physician, and prepare for rapid evaluation or intervention as ordered.

Bruising at the insertion site is common and usually not emergent. Mild numbness in the toes may indicate transient nerve irritation or edema and should be evaluated, but it is not as urgent as a diminished distal pulse. A slight rise in heart rate can occur from pain or anxiety and is typically monitored rather than an immediate emergency unless accompanied by other alarming signs.
