A nurse is providing teaching to a client who has a new diagnosis of type 2 diabetes mellitus. The nurse should recognize that the client understands the teaching when he identifies which of the following as manifestations of hypoglycemia? (Select all that apply)
Explanation & Rationale
Rationale: A. Tachycardia: Hypoglycemia activates the sympathetic nervous system, leading to adrenergic symptoms such as tachycardia, palpitations, and tremors. This is an early warning sign that glucose levels are too low. B. Blurred vision: Inadequate glucose supply to the brain and eyes can impair normal visual function. Blurred vision is a common neuroglycopenic manifestation of hypoglycemia. C. Polydipsia: Excessive thirst is associated with hyperglycemia, not hypoglycemia. High blood glucose causes osmotic diuresis, leading to dehydration and increased thirst, which differentiates it from low blood glucose episodes. D. Polyuria: Frequent urination occurs with hyperglycemia due to osmotic diuresis. Hypoglycemia does not cause excess urine output and instead presents with neurologic and adrenergic symptoms. E. Moist, clammy skin: Low blood sugar activates the autonomic nervous system, causing sweating and pallor. Moist, clammy skin is a classic physical finding in clients experiencing hypoglycemia.
