Post-procedure, which assessment should be routinely performed to ensure adequate blood flow to the extremities after catheterization?

• A. Blood glucose
• B. Peripheral pulses distal to the puncture site
• C. Visual acuity
• D. Lung auscultation

Answer: (B)

After catheterization, the most reliable way to confirm that blood is flowing adequately to the affected limb is to regularly assess distal peripheral pulses. These pulses reflect arterial perfusion beyond the access site, so any weakening or absence can signal problems like arterial occlusion, hematoma compressing the vessel, or vasospasm. In addition to pulses, observing skin color and temperature and checking cap refill can enhance early detection of compromised flow. Other assessments, such as blood glucose, visual acuity, or lung sounds, don’t provide direct information about limb perfusion and are not useful for monitoring this particular risk. Prompt detection of reduced distal perfusion allows timely intervention to prevent serious complications.
