What should the HHA do immediately if a client with diabetes feels very nervous and jittery?

The most appropriate action for the Home Health Aide (HHA) to take when a client with diabetes feels nervous and jittery is to give her a glass of orange juice. This response is correct because the symptoms of nervousness and jitteriness can be indicative of low blood sugar or hypoglycemia, which is a common concern for individuals with diabetes.

Orange juice is a quick source of glucose, and consuming it can help raise blood sugar levels rapidly. This is crucial because addressing low blood sugar promptly can prevent more severe symptoms and complications, including confusion, loss of consciousness, or seizures.

While providing water or monitoring blood sugar levels are important aspects of diabetes care, they do not address immediate hypoglycemia effectively. Water does not provide the carbohydrates necessary to raise blood sugar, and simply monitoring levels without intervening would mean delaying necessary treatment. Calling for emergency help may become necessary if the individual's condition worsens, but the first step should be to provide a quick source of sugar to address the immediate symptoms.
