A nurse is assessing a client who has type 1 diabetes mellitus and was administered insulin lispro 1 hr ago. Which of the following manifestations indicates that the client might be experiencing hypoglycemia?

Rationale: A. Confusion: Confusion is an early neurological manifestation of hypoglycemia caused by insufficient glucose supply to the brain. Clients may also experience irritability, shakiness, or difficulty concentrating, which are key indicators to assess for after insulin administration. B. Acetone breath: Acetone or fruity breath odor is associated with diabetic ketoacidosis (DKA), a hyperglycemic emergency, not hypoglycemia. This occurs due to ketone buildup when insulin is deficient, which is opposite of low blood glucose. C. Polydipsia: Excessive thirst is a symptom of hyperglycemia, not hypoglycemia. It occurs when elevated glucose levels cause osmotic diuresis, leading to dehydration and thirst, and is not expected shortly after insulin lispro administration. D. Hot, dry skin: Hot, dry skin is typically associated with hyperglycemia or fever. In hypoglycemia, the client often exhibits cool, clammy skin due to sympathetic nervous system activation and sweating, making this finding inconsistent with low blood glucose.
