What is the recommended emergency treatment for a person experiencing low blood sugar?

The recommended emergency treatment for a person experiencing low blood sugar is to consume a high sugar food such as hard candy or fruit juice. This is correct because when someone has low blood sugar (hypoglycemia), their glucose levels in the blood drop below normal, which can lead to symptoms such as dizziness, confusion, and weakness. Consuming a fast-acting source of sugar can quickly raise blood glucose levels back to safety. Foods like hard candy or fruit juice are effective because they deliver glucose into the bloodstream rapidly, helping to alleviate symptoms and stabilize the person.

In contrast, drinking a large glass of water does nothing to address low blood sugar as it does not provide any glucose. Eating a high-protein snack may be beneficial for sustained energy but is not effective in quickly raising blood sugar levels in an emergency situation. Lastly, simply resting until symptoms subside without eating can be dangerous, as the person may continue to experience low blood sugar, potentially leading to severe complications. It is essential to promptly address the low blood sugar with a rapid source of glucose.
