What is a key indicator that glucose administration has had a positive effect?

• A. Blood glucose level normal immediately
• B. No change in respiratory rate
• C. Increased sweating only
• D. Improvement in mental status and stabilized vital signs

Answer: (D)

Glucose therapy is aimed at reversing brain glucose deprivation, so the most meaningful sign it’s worked is when the patient’s mental status improves and their vital signs stabilize. When brain cells receive glucose again, confusion, agitation, or weakness often lessen, and as the body’s stress response eases, heart rate, blood pressure, and breathing tend to come toward normal ranges. A normal blood glucose reading right away isn’t always guaranteed, and relying on peripheral signs like sweating or only a change in one vital sign can be misleading. The combination of better mental status and steadier vital signs is the best evidence that glucose has had the desired effect.
