College Answer

An anatomy question expects the use of anatomical nomenclature to describe relationships. Good answers defined the “safe triangle” for the lateral approach, soft-tissue layers passed through from skin to pleura and relationship of the neurovascular bundle to the ribs and intercostal muscles. Additional marks were gained for describing the anterior approach and related structures. Common omissions included description of deeper structures (relations) including intrathoracic and intra-abdominal organs and level of the diaphragm with regard to rib space.

No marks were awarded for a description of intercostal catheter insertion
