How long should hemostatic agents be applied with direct pressure?

1 minute
2 minutes
3 minutes
4 minutes

The correct answer is: 3 minutes

Applying hemostatic agents with direct pressure for an appropriate duration is crucial in effectively controlling bleeding. The correct duration of three minutes is based on guidelines provided in trauma care protocols, which emphasize giving the hemostatic agent time to work effectively in conjunction with direct pressure. During this period, the pressure applied helps to both promote clot formation and prevent further blood loss, ensuring that the treatment is as effective as possible. If insufficient time is given—like one or two minutes—the agent may not have enough opportunity to interact with the blood, potentially leading to inadequate hemostasis and increased risk of complications. Meanwhile, extending the pressure beyond the recommended time may not provide additional benefits and could unnecessarily compromise the tissue around the wound site. Hence, three minutes strikes a balance, allowing sufficient time for the agent to function while maintaining the effectiveness of direct pressure in staunching hemorrhage.
