A nurse is reinforcing discharge teaching with the parent of a child who has a new diagnosis of diabetes mellitus. Which of the following statements by the parent requires a clarification of the teaching?

A. ``Sweating can occur with hypoglycaemia." Sweating is a common symptom of hypoglycemia due to the activation of the sympathetic nervous system. This statement is accurate and does not require clarification. B. "My son might have nausea and vomiting with hypoglycemia." Nausea and vomiting are typically associated with hyperglycemia and diabetic ketoacidosis (DKA), not hypoglycaemia. Hypoglycaemia usually presents with symptoms like sweating, shakiness, confusion, and hunger. This statement indicates a misunderstanding that needs to be clarified. C. ``My son might complain of feeling shaky when he has a low blood glucose level." Feeling shaky is a common symptom of hypoglycemia due to the body's response to low blood glucose levels. This statement is correct and does not need clarification. D. "The onset of low blood glucose usually occurs rapidly." Hypoglycaemia often has a rapid onset, particularly when caused by factors like excessive insulin or missed meals. This statement is accurate and does not require clarification.
