ممرض يعمل علاجاً طبيعياً للصدر بالقرع والتصريف الوضعي. أين يُطبق القرع؟

A nurse performs chest physiotherapy with percussion and postural drainage. Where is percussion applied?

1. Directly over the spine because it is the closest point to the lungs
2. On the abdomen to move the diaphragm
3. Over the ribs above the segment, avoiding spine and kidneys
4. Over the kidneys to move secretions downward

Answer: C) Over the ribs above the segment, avoiding spine and kidneys. Percussion uses a cupped hand over the ribs above the segment to drain, avoiding the spine, kidneys, breasts and wounds. It is avoided with recent haemoptysis, rib fractures and instability.
