A nurse is caring for a client with pneumonia. The client's oxygen saturation is below normal. What abnormal respiratory process does this demonstrate?
A) changes in the alveolar-capillary membrane and diffusion
B) alterations in the structures of the ribs and diaphragm
C) rapid decreases in atmospheric and intrapulmonic pressures
D) lower-than-normal concentrations of environmental oxygen
Ans: A
Any change in the surface area of the lungs hinders diffusion of gas exchange. Any disease or condition that results in changes in the alveolar-capillary membrane, such as pneumonia or pulmonary edema, makes diffusion more difficult, assessed by decreased oxygen saturation measurement.
