Knowing the high incidence and prevalence of heart failure among the elderly, the manager of a long-term care home has organized a workshop on the identification of early signs and symptoms of heart failure. Which of the following teaching points is most
 
  A)
  Displays of aggression, confusion, and restlessness when the resident has no history of such behavior can be a sign of heart failure.
  B)
  Heart failure will often first show up with persistent coughing and lung crackles.
  C)
  Residents in early heart failure will often be flushed and have warm skin and a fever.
  D)
  Complaints of chest pain are actually more often related to heart failure than to myocardial infarction.

Question 2

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.

Answer to Question 1

Ans:
A

Feedback:

Cognitive changes can often accompany heart failure in the elderly. Pulmonary edema is a later sign, and they are less likely to display coughing, chest pain of flushed skin, and fever.

Answer to Question 2

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.
