One of the liberties of being "just a scrub nurse" was the privilege of asking dumb, foolish questions. When there was a lull in surgical action such as waiting for a phone call from pathology or passing time until an esoteric instrument was flashed, the time was ripe to pose philosophical queries to the attending surgeon. Surgeons could come up with some convoluted answers to foolish questions when they were caught off guard. Timing and delivery of the question was the key to obtaining an offbeat answer.
Here is a sampling of some questions I asked in a foolish attempt to resolve the greatest mysteries of the operating room; "Why do cloth shoe covers track blood on the floor a greater distance than new-fangled plastic disposable covers?... How normal is 0.9 saline?... Can you sleep on a mattress suture?... and perhaps the ultimate question... "Why is the working end of many surgical instruments curved?"
