In which scenario is external bleeding MOST difficult to control?

• A. Small scalp laceration
• B. Fingertip bleed
• C. Femoral artery laceration with a blood pressure of 140/90 mm Hg
• D. Nosebleed

Answer: (C)

When bleeding comes from a large, high‑pressure artery, control becomes much harder. A femoral artery laceration dumps blood at a rapid, constant flow, and the vessel is deep in the thigh, making it difficult to compress effectively with just direct pressure. Even with firm pressure, the high arterial pressure (as implied by a normal/near-normal blood pressure) makes clot formation slower and bleeding harder to stop, so a tourniquet or rapid hemorrhage-control measures are often required. In contrast, a small scalp laceration, fingertip bleed, or nosebleed involves smaller vessels or lower-pressure bleeding that typically respond well to direct pressure or simple packing. That’s why the femoral artery injury presents the most challenging external bleed to control.
