What is a potential serious complication of an arterial puncture after a cardiac catheterization?

• A. Arterial bleed leading to shock
• B. Increased appetite
• C. Hair growth
• D. Weight loss

Answer: (A)

Arterial puncture during cardiac catheterization carries a real risk of significant bleeding because arterial pressure is high. If bleeding is not quickly controlled, it can lead to a large loss of blood and hypovolemic shock, which is why arterial bleeding is considered a serious complication. The puncture can also produce a hematoma or, in certain access sites like the femoral artery, a retroperitoneal bleed that worsens instability. Recognize signs such as increasing pain, swelling, or changes in vital signs, and respond with prompt direct pressure and appropriate hemostasis and monitoring. The other options don’t fit with this procedure—increased appetite, hair growth, and weight loss aren’t typical complications of an arterial puncture after cardiac catheterization.
