A nurse is providing a client with preoperative education. The nurse knows which of the following teaching points should be included in the instruction regarding deep breathing and coughing exercises?
A)
"When you are lying down, your body ends up needing more oxygen."
B)
"One needs to breathe deeper while lying flat in bed since this increases the work load on the diaphragm."
C)
"The resistance of your bed limits your lung expansion."
D)
"We want you to be able to use your abdominal muscles more, rather than depending on movement of your chest cage for breathing."
Ans:
C
Feedback:
The resistance of the bed in a supine position limits lung expansion and, ultimately, oxygenation. Inactivity does not increase oxygen demand, and patients tend to breathe more shallowly. The goal is to use abdominal muscles less and the chest cage more.
