Which of the following is a sign or symptom of low blood sugar?

• A. Weight gain
• B. Hypertension
• C. Rash
• D. Confusion

Answer: (D)

Low blood sugar limits the brain’s fuel supply, causing changes in mental status. Confusion is a classic sign because the brain cannot function properly without glucose, leading to difficulty thinking, disorientation, or impaired judgment. The other options don’t reflect the brain’s response to low glucose, so they aren’t associated with hypoglycemia. When someone at risk shows confusion, it’s important to check their blood sugar and treat promptly.
