What should the nurse prepare to do when a diabetic client is weak, tired, and does not respond?

In scenarios where a diabetic client presents as weak, tired, and non-responsive, administering glucose is essential and appropriate for several reasons. These symptoms often indicate potential hypoglycemia, which is a condition characterized by abnormally low blood sugar levels. When blood glucose levels decrease significantly, the body does not have enough energy to function adequately, leading to symptoms such as weakness and fatigue.

By administering glucose, the nurse can quickly elevate the client's blood sugar levels, providing the necessary energy for brain function and overall metabolic processes. This intervention is critical in preventing further complications, such as loss of consciousness or seizures, which can occur with severe hypoglycemia.

While other options such as administering insulin or contacting a physician may be relevant in different contexts, in the immediate scenario of weakness and non-responsiveness, the priority is to address potential low blood sugar. Checking blood pressure could be relevant in evaluating the client's overall condition but does not directly address the most pressing issue of suspected hypoglycemia.
