The large, heavy, and older adult patient, post stroke, develops an infected decubitus on the sacrum during the hospital stay. When the patient goes home, about 2 weeks later, the patient returns to the hospital with pneumonia. The distinction between these two infections is which of the following?
A. The decubitus is considered to be caused by protozoa, whereas the pneumonia is termed unpreventable because of the size of the patient.
B. The decubitus and pneumonia are caused by the same host.
C. The decubitus infection was transmitted from other patients on the unit, but the pneumonia was transmitted from a neighbor visiting when the patient was at home.
D. The decubitus is termed nosocomial and the pneumonia is termed community-acquired.
D. Because the decubitus developed during the stay in a health care facility, it is classified as nosocomial. Because the patient did not have pneumonia when he left the facility, it is classified as community-acquired.
