In treating shock, lying the person down with their head lower than their feet is aimed at:

The correct answer is focused on increasing blood flow to the brain. When a person is in shock, their body may struggle to maintain adequate blood circulation due to various factors such as blood loss or dehydration. By positioning the individual with their head lower than their feet, known as the Trendelenburg position, gravity aids in directing blood flow back towards the vital organs, especially the brain and heart. This positioning can help to revive the body’s circulation and oxygen delivery to critical areas, which is essential for combating the symptoms of shock.

While the other answers mention important aspects of care, such as reducing anxiety, promoting comfort, and restoring consciousness, they do not specifically address the physiological goal of increasing cerebral blood flow, which is crucial for treating shock effectively.
