Which statement is true about innocent murmurs in children during evaluation?

• A. They are best heard in diastole
• B. The murmur radiates to the axilla
• C. There is no variation with changes in position
• D. The intensity is no greater than I or II/VI

Answer: (D)

The main idea is that innocent murmurs in children are typically soft and uncomplicated, so their intensity is usually limited to a low grade on the standard 6-point scale. In practice, these benign murmurs are seen as systolic and rarely louder than a grade II/VI, which is why the statement about intensity being no greater than I or II/VI is the true description. This softness helps distinguish them from murmurs that suggest disease. Other clues that point away from innocence: being best heard in diastole would raise concern for a pathology rather than an innocent murmur, radiating to the axilla suggests valvular regurgitation rather than an innocent murmur, and many innocent murmurs actually change with body position or breathing, so a lack of variation with position isn’t typical. So, the correct understanding is that innocent murmurs are generally gentle, systolic, nonradiating, and do not exceed a low grade in intensity.
