How can hypoglycemia be treated effectively?

1. Administration of insulin

2. Food containing glucose or intravenous dextrose

3. Use of antihistamines

4. Blood transfusion

The correct answer is: Food containing glucose or intravenous dextrose

Hypoglycemia, which refers to abnormally low levels of glucose in the blood, can be effectively treated with food containing glucose or intravenous dextrose because these methods directly increase blood sugar levels. When a person is experiencing hypoglycemia, their immediate need is to raise their glucose levels quickly to prevent symptoms like confusion, weakness, seizures, or even loss of consciousness. Consuming foods that are high in glucose—such as sugary snacks or drinks—provides a rapid source of carbohydrates that the body can quickly convert into usable energy. In cases where a person is unable to swallow or has a severe hypoglycemic reaction, intravenous administration of dextrose provides a fast and controlled way to raise blood sugar levels, making it a critical intervention in emergency settings. Other options, such as insulin administration, would be counterproductive since insulin lowers blood sugar levels, while antihistamines and blood transfusions are unrelated to managing blood glucose levels. Therefore, the most effective treatment for hypoglycemia centers around quickly providing glucose or dextrose.
