Which of the following is a risk at the entry site during a cardiac catheterization?

• A. Bleeding at the entry site
• B. Weight loss
• C. Hair growth
• D. Improved memory

Answer: (A)

When a catheter is threaded into a blood vessel for a cardiac procedure, the body relies on rapid sealing of the puncture after the device is removed. The most likely risk at the entry site is bleeding. This happens because the procedure involves puncturing an artery and patients are often heparinized or otherwise anticoagulated to prevent clotting during the test. If the puncture site doesn’t seal promptly, blood can escape into surrounding tissues, causing a visible hematoma or even more serious bleeding.

Understanding this helps explain why bleeding at the entry site is the central concern: it is a direct consequence of creating an arterial access point and the need for anticoagulation, whereas other options listed—weight loss, hair growth, or memory improvement—are not related risks of vascular entry during catheterization.

Clinically, you’d monitor the access site for ongoing bleeding, swelling, or expanding hematoma, and manage with firm direct pressure, appropriate reversal or adjustment of anticoagulation as needed, and, if indicated, vascular closure devices.
