What are the three main objectives in first aid for shock?

The main objectives in first aid for shock focus on stabilizing the patient and preventing the condition from worsening. Ensuring the patient is breathing is crucial, as inadequate oxygenation can lead to further complications. Stopping external bleeding is a priority since significant blood loss can exacerbate shock, leading to a critical reduction in blood flow to vital organs. Maintaining body temperature is also important because shock can cause the body to become hypothermic, which can hinder the body’s ability to recover and respond to treatment.

The other options do not align as closely with the immediate first aid priorities for shock. While monitoring vital signs is important in a clinical setting, immediate first aid focuses on stabilizing the patient through breathing, controlling bleeding, and ensuring they maintain body temperature. Hydration is also vital but is secondary compared to the more urgent needs presented in the correct answer.
