St. John Ambulance First Aid Practice Exam

In the case of a diabetic emergency, particularly hypoglycemia (low blood sugar), it is crucial to quickly and effectively raise the person's blood sugar levels. If the individual is conscious and able to swallow, providing sugar or glucose is the correct response. This is because quick sources of sugar, such as glucose tablets, juice, or candies, can quickly restore normal blood sugar levels and help alleviate symptoms such as confusion, dizziness, and weakness.

Providing water may not directly address the underlying issue of low blood sugar and will not provide the immediate boost of glucose needed. Administering insulin is inappropriate during hypoglycemic events, as this would only lower blood sugar levels further and worsen the situation. Encouraging a person to walk around might also be counterproductive, as physical activity can further deplete their blood sugar levels instead of helping them recover.

Thus, offering sugar or glucose is the correct and most effective response to manage someone experiencing a diabetic emergency when they are conscious.
