A pre-school age child with a congenital heart defect is brought to the clinic by the parent because of a fever and an earache. During the assessment, the parent asks the nurse why the child is at the 5th percentile for weight and height for age. Which response is best for the nurse to provide?

A. "You should not worry about the growth tables. They are only averages for children.": Growth charts are standardized tools used to compare a child’s development with expected norms. Dismissing the concern overlooks an important clinical sign and fails to address the parent’s valid question. B. "Haven't you been feeding according to recommended daily allowances for children?": This response places blame on the parent and does not acknowledge the child’s medical condition. It may also create unnecessary guilt rather than offering supportive education. C. "Does your child seem mentally slower than his peers also?": Asking about developmental delay in this way is inappropriate and insensitive. It shifts the focus to cognitive ability rather than addressing the physical growth concern directly tied to the child’s condition. D. "The smaller size is probably due to the heart disease.": Children with congenital heart defects often experience poor growth because of increased metabolic demands and reduced energy available for growth. This response gives the parent a clear, accurate explanation while validating the concern.
