If a patient displays symptoms of hyperglycaemia and is conscious, what is the first thing you should ask the patient?

When a patient exhibits symptoms of hyperglycaemia, it is essential to assess their food intake because this could provide immediate insight into their condition. Asking when the patient last ate helps determine if they have had inadequate food intake relative to their insulin or other diabetes medications. This is crucial because hyperglycaemia can result from not eating properly, which may lead to an imbalance in blood glucose levels. Understanding their last meal can also help you assess whether they may need immediate intervention, such as insulin administration or adjustments in their treatment plan.

In contrast, questions about medications, feelings, or recent blood sugar checks, while potentially useful, do not directly address the immediate situation related to food intake and its impact on blood sugar levels. These considerations can follow after assessing the patient's last meal, ensuring the response is both timely and relevant to managing hyperglycaemia.
