Answer: Neuromuscular drugs are used to facilitate endotracheal intubation and to paralyze patients who are on mechanical ventilation so that they will not resist the inflow of air from the ventilator. Drugs are also used to sedate patients who are intubated and on the ventilator. 64. Provide a brief history of Legionnaire’s disease, describe the scientific name for the bacterium that causes Legionnaire’s disease, and how that name indicates its affect on the body. Answer: Legionnaire’s disease, a serious and sometimes fatal pneumonia caused by the bacterium Legionella pneumophila, was named for its first recognized outbreak, which occurred in 1976 at an American Legion convention in Philadelphia. This gram-negative bacterium grew in standing water in the air conditioning system of the convention center and was distributed through ventilation ducts. The bacterium is especially attracted to the environment in the lungs, and so its full scientific name is Legionella (based on where it originated) and pneumophila (which means thing that loves the lungs).
