What symptom should a nurse expect to see in a client with a capillary blood glucose reading of 48 mg/dL?

In a client with a capillary blood glucose reading of 48 mg/dL, diaphoresis, or excessive sweating, is a common symptom linked to hypoglycemia. When blood sugar levels drop significantly, the body responds by releasing hormones, such as adrenaline, that stimulate the fight-or-flight response. This leads to increased sweating, racing heartbeat, and feelings of anxiety.

The other symptoms listed may not be the primary manifestations of hypoglycemia. Excessive thirst is typically associated with hyperglycemia, not low blood sugar levels. Confusion can be a symptom of severe hypoglycemia as well, but diaphoresis is often one of the first noticeable signs. Increased urination generally relates to high blood sugar levels as well, further distinguishing it from hypoglycemic reactions. Therefore, in this situation, diaphoresis is the most expected symptom.
