Legionnaires’ disease 军团病；退伍军人症
159. Correct answer: b.
Legionella bacillus is found in water; so a person can become infected by aspirating contaminated water or inhaling spray from a shower of contaminated water. Tetanus is found in soil and the organism causing histoplasmosis is found in bird feces.
160. Correct answer: c.
An infant awaiting repair of a T/E fistula should be positioned in semi-Fowler’s position to decrease the risk of stomach contents being regurgitated and entering the trachea. Side lying and dorsal recumbent positions do not contribute to the pull of gravity in preventing backflow of stomach contents into the esophagus and Trendelenburg position in which the head is lower than the body actually encourages the backflow.
