Which signs indicate glucose has improved after administration?

• A. No change in symptoms
• B. Worsening confusion
• C. Increased blood pressure only
• D. Improvement in mental status, stabilized vital signs, and reported feeling better

Answer: (D)

When treating suspected hypoglycemia, you look for signs that glucose has restored brain function and overall stability. A true improvement shows up as the brain getting its fuel back—mental status improves, such as becoming more alert, oriented, and cooperative. In parallel, vital signs should settle toward normal ranges as the body’s sympathetic response settles and glucose supplies energy to organs. The patient may also report feeling better, with reduced dizziness or weakness. If there’s no change, or if only one parameter changes (like blood pressure going up) without improved mental status or overall well-being, that suggests glucose hasn’t produced the expected effect yet. Therefore, improvement in mental status, stabilized vital signs, and the patient’s feeling better best reflect a positive response to glucose.
