Question: 1 / 400

Which intervention is least effective in controlling arterial bleeding?

Applying a pressure bandage

Using a tourniquet

Using direct pressure

Monitoring the patient's vital signs

Monitoring the patient's vital signs is the intervention least effective in controlling arterial bleeding. While vital sign assessment is crucial for understanding the patient's hemodynamic status and can help guide further treatment, it does not actively address the source of arterial bleeding.

In contrast, applying a pressure bandage, using a tourniquet, and employing direct pressure are all interventions designed to stop or minimize blood loss. These methods physically obstruct blood flow from the affected artery, making them direct approaches to treating bleeding. In emergency situations, immediate actions to control bleeding are vital, whereas monitoring vital signs, though important for overall patient assessment and care strategy, takes precedence after the more immediate life-threatening issue of bleeding is addressed.
