The nurse is encouraging a client to cough frequently and complete deep breathing exercises. The nurse knows that many factors can cause a decrease of gas exchange for clients.
 
  Based on this information, what are factors that can cause a decrease in gas exchange?
  1 . Immobility
  2 . Shaken baby syndrome
  3 . Thoracic/pulmonary surgery
  4 . Pneumonia
  A) 1, 2, 3
  B) 1, 2, 4
  C) 1, 3, 4
  D) 2, 3, 4

Question 2

The nurse is reviewing the diagnostic test results for a client on the pulmonary care unit. Based on this information, what diagnostic test result would best lead to stimulation of the medulla to increase respirations?

  B) High carbon dioxide
  C) High oxygen
  D) Low pH

Answer to Question 1

C
Feedback:
Many factors can cause a decrease in gas exchange, including immobility, thoracic/pulmonary surgery, or pneumonia. Encouraging frequent coughing and deep breathing exercises should assist in improving oxygen delivery to the lungs and tissues. Certain portions of the brain stem are particularly sensitive during infancy; neurons can be destroyed if the child is shaken violently or dropped. This results in shaken baby syndrome and can lead to death.

Answer to Question 2

D
Feedback:
An excess of carbon dioxide in the blood of a healthy person lowers the pH of the blood. This drop in pH leads to stimulation of the medulla to increase respirations, which provides a means for blowing off excess carbon dioxide.
