A nurse is caring for two patients, one has pneumonia, and the other was in a car accident and has a broken leg and arm. The patient with pneumonia is having a severe coughing episode, so the nurse
rushes into the room and suctions the mucus out of the patient's' trachea so he may breathe better.
Unfortunately, she doesn't put on gloves or a mask. Four days later, the patient who had been in a car
accident develops a severe cough and complains of difficulty breathing. His chest x-ray shows
pneumonia. Using the chain of infection, describe how this patient contracted pneumonia.
