What symptom should a CNA be observant of in a diabetic resident?

A Certified Nursing Assistant (CNA) should be particularly observant of signs of hypo- or hyperglycemia in a diabetic resident because these conditions represent acute changes in blood sugar levels that require immediate attention. Hypoglycemia occurs when blood sugar drops too low, which can lead to symptoms such as confusion, shaking, sweating, and in severe cases, loss of consciousness. Hyperglycemia, on the other hand, happens when blood sugar is too high, leading to symptoms like increased thirst, frequent urination, fatigue, and blurred vision. Recognizing these signs is crucial because timely intervention can prevent serious complications or emergency situations.

Monitoring these symptoms helps ensure that appropriate measures are taken to manage the resident's condition effectively, such as administering insulin for hyperglycemia or providing carbohydrates for hypoglycemia. While the other options might reflect symptoms that can occur in diabetes, they do not speak as directly to acute, life-threatening conditions that require prompt action, which is why focusing on changes in blood sugar is of utmost importance for a CNA in the care of diabetic residents.
