Which of the following is an appropriate treatment for low blood sugar?

When addressing low blood sugar, or hypoglycemia, the most effective and immediate treatment is the administration of fast-acting carbohydrates. This approach is based on the need to quickly elevate blood glucose levels to prevent further complications associated with low blood sugar, such as confusion, seizures, or loss of consciousness.

Fast-acting carbohydrates, typically in the form of glucose tablets, fruit juice, or regular soda, allow for rapid absorption and provide an immediate source of sugar that can increase blood glucose levels. The recommended amount is often around 15 grams, making it a standard and effective response to quickly rectify hypoglycemia.

In contrast, other options do not provide the immediate benefit necessary for treating low blood sugar. For example, administering insulin would exacerbate the problem by lowering blood glucose levels further. High-protein snacks and slow-acting carbohydrates, while important for overall nutrition, do not act quickly enough to address acute hypoglycemia. They may be beneficial for longer-term management of blood sugar levels, but they cannot swiftly counteract a low blood sugar incident.
