You are providing education to a client with diabetes regarding hypoglycemia. Which of the following statements would be included in the teaching?

Choice A reason: Increasing Lantus (glargine) in response to low blood glucose is dangerous and contraindicated. Glargine is a long-acting basal insulin; increasing the dose would further lower blood glucose levels over the next 24 hours, severely exacerbating the hypoglycemia and potentially leading to a life-threatening coma. Choice B reason: Hypoglycemia actually triggers the sympathetic nervous system, not the parasympathetic system. This "adrenergic" response results in tachycardia, tremors, diaphoresis, and anxiety. Bradycardia is not a standard clinical sign of an acute hypoglycemic event; rather, the heart rate typically increases as a stress response. Choice C reason: Hypoglycemia occurs when there is an imbalance between insulin, glucose intake, and energy expenditure. Consuming too little carbohydrate to meet metabolic demands, or increasing physical activity without adjusting insulin or food intake, causes blood glucose levels to drop below the normal physiological range (typically < 70 mg/dL). Choice D reason: Hypoglycemia is a metabolic emergency that requires the immediate ingestion of fast-acting carbohydrates (the "Rule of 15"). Rest and fluid intake without a glucose source will not correct the low blood sugar level and may allow the patient's neurological status to deteriorate further.
