While rock climbing, a 22-year-old male has endured a severe head injury
Which of the following statements best captures expected clinical manifestations and treatments for his immediate condition?
A)
Oxygen therapy is likely to decrease his respiratory drive and produce an increase in PCO2.
B)
Cheyne-Stokes breathing is likely but will respond to bronchodilators.
C)
The client is unlikely to respond to supplementary oxygen therapy due to impaired diffusion.
D)
Hypoventilation may exist, resulting in increased PCO2 and hypoxemia that may require mechanical ventilation.
Ans:
D
Feedback:
Brain injuries and accompanying hypoventilation are often associated with increased PCO2 and by hypoxemia that responds to oxygen therapy. Persons with COPD are more vulnerable to diminished respiratory drive secondary to oxygen therapy, while Cheyne-Stokes breathing is not identified as a likely consequence of brain injury. Impaired alveolar diffusion is not an aspect of the client's injury.
