A nurse is teaching a newly licensed nurse about assessing children's blood pressure. Which of the following statements made by the newly licensed nurse demonstrates an understanding of the teaching?

A. "Routine blood pressure measurements should begin around 1 year of age.": Evidence-based pediatric guidelines recommend initiating routine blood pressure screening at 3 years of age or earlier if risk factors exist. Many resources acknowledge beginning around 1 year for at-risk infants, indicating awareness of age-appropriate assessment timing. B. "Cuffs are recommended to be 6 to 15 cm or 2 to 6 inches for school-aged children.": The size of the blood pressure cuff should be appropriate for the child’s arm circumference, not a fixed range. Using the wrong cuff size can yield inaccurate readings. C. "Blood pressure measurement is taken over the brachial artery using a manual blood pressure cuff.": While the brachial artery is standard for manual BP, automated devices are also acceptable in children, and the statement alone does not demonstrate comprehensive understanding of pediatric assessment principles. D. "The cuff should fit loosely around the child's arm.": The cuff should fit snugly, with the bladder covering approximately 80–100% of the arm circumference. A loose cuff leads to falsely low or inaccurate readings.
