The practical nurse (PN) is caring for a client newly diagnosed with diabetes mellitus (DM). Which finding is an early sign of hypoglycemia?

Hypoglycemia occurs when blood glucose levels drop below normal levels. It is commonly associated with diabetes mellitus and can result from various factors such as excessive insulin or oral hypoglycemic medication, delayed or missed meals, increased physical activity, or alcohol consumption. Tremors, or shaking hands, are one of the early signs of hypoglycemia. They can occur due to the brain's response to low blood glucose levels. Other early signs of hypoglycemia may include sweating, palpitations, anxiety, hunger, and weakness. A. Polyuria, or excessive urination, is not typically associated with hypoglycemia. It is more commonly seen in conditions such as hyperglycemia or diabetes insipidus. C. Bradycardia, or a slow heart rate, is not a characteristic sign of hypoglycemia. It can occur in some cases of severe hypoglycemia, but it is not an early sign. D. Difficulty swallowing is not directly related to hypoglycemia. It may be caused by other factors such as neurological or muscular conditions, esophageal disorders, or structural abnormalities in the throat or esophagus.
