The primary reason a client with chronic obstructive pulmonary disease (COPD) often experienc-es fatigue and activity intolerance is related to:
 
  1. The increased presence of surfactant that results in sticky alveoli
  2. The presence of chronic infections in the lungs and bronchial tree
  3. The extra energy that is needed to exhale the air from the damaged lungs
  4. The client's elevated anxiety level related to the air hunger being experienced

Question 2

When the nurse is reviewing a client's laboratory results, a low calcium level is noted. When the nurse then reviews the client's electrocardiogram, the most likely change noted will be a(n):
 
  1. Increased Q-T interval
  2. Increased P-R interval
  3. Q-T interval less than 0.12 seconds
  4. QRS interval greater than 0.12 seconds

Answer to Question 1

ANS: 3
Clients with advanced COPD lose the elastic recoil of the lungs and thorax. As a result, the cli-ent's work of breathing increases. Although the remaining options are not incorrect, they are not the primary source of the client's fatigue.

Answer to Question 2

ANS: 1
The normal Q-T interval is 0.12 to 0.42 second. Changes in electrolyte values, such as hy-pocalcemia, or therapy with drugs such as disopyramide or amiodarone increase the Q-T interval. The remaining options do not reflect a low calcium level.
