Final answer:
The least suggestive sign of a diabetic emergency is bradycardia.
Step-by-step explanation:
The least suggestive sign of a diabetic emergency is A) Bradycardia.
Bradycardia refers to a slow heart rate, which is not typically associated with a diabetic emergency. Instead, a diabetic emergency is more commonly characterized by symptoms such as rapid breathing, fruity breath odor, combativeness, and tachycardia (a fast heart rate).
For example, deep, rapid breathing is often seen in ketoacidosis, a severe complication of diabetes, as the body tries to compensate for the buildup of acids in the blood. Fruity breath odor is also a common symptom of ketoacidosis due to the exhalation of acetone. Combativeness and tachycardia can be signs of the body's stress response to the diabetic emergency.
