Which strategy is least effective when dealing with a casualty in shock?

The least effective strategy when dealing with a casualty in shock is engaging in frantic speech to maintain alertness. When a person is in shock, they often experience heightened anxiety, confusion, and distress, which can be exacerbated by frantic communication. Using calm and reassuring language is critical during this time because it helps to stabilize the casualty's emotional state and can reduce their stress. Keeping the casualty informed about what actions are being taken also helps in building their trust and reduces feelings of helplessness. Offering physical comfort, such as touch or ensuring the casualty is in a comfortable position, can have a soothing effect and promotes a sense of safety. Therefore, a calm and composed approach is essential to effectively manage a casualty presenting with shock, whereas frantic speech can create additional panic and hinder the overall care process.
