Answer: A."A fenestrated tube has holes in allowing for better speech ability. However, if you suction a trach that is fenestrated, the suction catheter could protrude through those holes and damage the tracheal lining. Therefore, a non-fenestrated inner cannula is inserted prior to suctioning. Consider the properties of a fenestrated tube. Damaging the tracheal lining would be serious problem, so preventing that would be the nursing priority."
