Which of the following is NOT a sign of hyperglycemia/diabetic coma?

The statement that "no thirst" is not a sign of hyperglycemia or diabetic coma is accurate. In hyperglycemia, the body typically experiences a state of dehydration due to increased urination as the kidneys attempt to excrete excess glucose. This process leads to dehydration, which is often accompanied by increased thirst or polydipsia. Therefore, an individual experiencing hyperglycemia would generally have a strong urge to drink fluids.

In contrast, the other signs listed are indeed characteristic of hyperglycemia or diabetic coma. A breath with a fruity odor results from acetone, a ketone body produced during fat metabolism when glucose is not adequately utilized. A fast, weak pulse may occur as the body attempts to compensate for low blood volume due to dehydration and may signal further physiological stress. Dry skin is a common symptom, as dehydration affects the body's overall hydration status, leading to less moisture in the skin.

Understanding the correct manifestations of hyperglycemia is essential for recognizing and responding to this condition effectively.
