If a passenger is conscious and experiencing low blood sugar, what is the first treatment step?

When a passenger is conscious and experiencing low blood sugar, the immediate treatment involves administering a source of sugar. This is crucial because low blood sugar, or hypoglycemia, can lead to symptoms like confusion, sweating, weakness, and potentially loss of consciousness. Giving sugar, such as in the form of orange juice, provides the body with the carbohydrates it needs to rapidly increase blood glucose levels.

Orange juice is particularly effective because it is easily absorbed and can quickly raise blood sugar levels, alleviating the symptoms of hypoglycemia. It is important that the person remains conscious and able to swallow before administering any oral treatment.

The other options are not appropriate first steps in this scenario. Insulin would be counterproductive, as it is used to lower blood sugar levels and could worsen the condition. Providing high-flow oxygen is typically reserved for situations involving respiratory distress or other critical conditions, not for low blood sugar. Monitoring pulse can be important in assessing overall patient condition, but prompt treatment of low blood sugar takes priority to prevent further symptoms or complications.
