T/F an emergency decompression of a tension pneumothorax can be performed with a 14 G cannula into the second intercostal space in the midclavicular line
T/F the second rib attaches to the sternum at the same point as the sternal angle (angle of Louis) – this landmark is reliably palpable
T/F IV cannulae can be too short to reach the pleural space
T/F the neurovascular bundle runs in a groove on the superior surface of each rib
T/F a chest drain (intercostal catheter) is usually inserted in the mid-axillary line in the 4th or 5th intercostal space (the nipple position in a male is usually the 5th intercostal space)
T/F if a chest drain is placed too posterior, the long thoracic nerve may be injured – this results in weakness of the serratus anterior muscle, and a ‘winged scapula’
T/F after insertion, the presence of a chest drain is usually not painful, because both the visceral and parietal pleura are poorly innervated

Can you name 6 procedures which can potentially cause a pneumothorax as a complication?
On the diagram below, draw and name the borders of the “triangle of safety” for lateral insertion of a chest drain.
