What is a common side effect associated with the use of oral glucose?

The correct response highlights a common side effect associated with oral glucose, particularly in patients with specific underlying conditions or reactions to the sugar. When oral glucose is administered, it is primarily intended to quickly increase blood sugar levels, especially in cases of hypoglycemia. While side effects can vary, nausea is notably common. This can occur as a result of rapid absorption of the glucose or if the individual already has a sensitive stomach or related gastrointestinal issues.

Increased heart rate may occur as a response to elevated blood glucose but isn’t a direct side effect of oral glucose. Airway obstruction is more related to mechanical issues or certain allergies rather than the consumption of glucose itself. Dizziness could result from a fluctuating glucose level rather than the glucose ingestion directly. Thus, nausea presents a more typical side effect one might observe with oral glucose ingestion, making it important for EMTs to monitor patients for such reactions after administration.
