Which statement best describes arterial bleeding?

• A. Bright red color and pulsating spurting flow
• B. Dark red color and steady flow
• C. Bright red color with a slow ooze
• D. Dark red color and a pulsating flow

Answer: (A)

Arterial bleeding is driven by high-pressure blood flow, so it tends to be bright red and come out with a pulsating spurting stream that matches the heartbeat. This combination—bright red color plus pulsatile spurting flow—is the hallmark of arterial injury and is the best match for describing arterial bleeding. The other descriptions align with different types of bleeding. Dark red blood that flows steadily points to venous bleeding, which has lower pressure and tends to ooze or steady leak rather than spurting. Bright red blood with a slow ooze doesn’t show the pulsatile character of arterial flow and is less typical of an arterial injury. Dark red blood that pulsates would mix the low-oxygen color of venous blood with pulsation, which isn’t characteristic of arterial blood.
