Which of the following is NOT a sign of hypoglycemia?

  1. Confusion and dizziness

  2. Excessive sweating

  3. Fruity breath

  4. Rapid heart rate

The correct answer is: Fruity breath

Fruity breath is typically associated with hyperglycemia, particularly in cases of diabetic ketoacidosis, rather than hypoglycemia. When blood glucose levels are excessively high, the body may break down fat for energy, producing ketones that can lead to a distinctive fruity or sweet-smelling breath. On the other hand, signs of hypoglycemia, such as confusion and dizziness, excessive sweating, and a rapid heart rate, are physiological responses to low blood sugar levels as the body reacts to insufficient glucose supply for energy. Recognizing these signs is critical for timely intervention in hypoglycemic situations.
