What clinical finding suggests hypoglycemia after administering regular insulin?

Cold sweats are a clinical finding that suggests hypoglycemia after administering regular insulin. When blood glucose levels drop too low, the body activates mechanisms to raise blood sugar, which includes the release of adrenaline (epinephrine). This hormone triggers sweating, especially on the palms and forehead, leading to the characteristic cold sweats.

This response is a part of the autonomic nervous system's reaction to hypoglycemia. Symptoms of hypoglycemia can also include shakiness, irritability, confusion, and in more severe cases, loss of consciousness or seizures. Recognizing cold sweats as a sign can help prompt timely intervention to prevent further complications from low blood sugar levels.

The other options describe symptoms associated with different conditions. Rapid, labored breathing typically indicates respiratory distress or metabolic issues. Increased appetite may occur as the body attempts to compensate for energy loss but is not a definitive sign of hypoglycemia. Increased urination is more often associated with hyperglycemia or diabetes-related conditions rather than hypoglycemia, as the body tends to retain fluid and reduce urination when glucose levels are low.
