MULTIPLE CHOICE

1. Which of the following would not be considered a common pulmonary consequence of neuromuscular disease?

ANS:  D

The pulmonary consequences of neuromuscular disease can include the following: hyperventilation or hypoventilation, sleep apnea, aspiration, atelectasis with resulting hypoxemia, pulmonary hypertension, and cor pulmonale.

DIF:    Recall             REF:   p. 642            OBJ:   1

2. Hypoventilation that occurs with progressive neuromuscular disease may be a protective mechanism that avoids acute respiratory muscle fatigue

ANS:  A

Some experimental data suggest that when hypoxemia is chronic, it may increase diaphragm muscle endurance. Thus, the hypoventilation that occurs with progressive neuromuscular disease may be a protective mechanism that avoids acute respiratory muscle fatigue. However, when hypoxemia is acute, it actually potentiates respiratory muscle fatigue, hastening respiratory failure.

3. Respiratory muscle weakness is associated with all of the following abnormalities except:

ANS:  A

Of the many neuromuscular problems causing pulmonary dysfunction, respiratory muscle weakness that leads to atelectasis, hypoxemia, and ventilatory insufficiency is among the best recognized.

DIF:    Recall             REF:   p. 642            OBJ:   2

4. Patients with respiratory muscle weakness due to neuromuscular disease may initially report with the following symptoms except:

ANS:  C

Patients with respiratory muscle weakness due to neuromuscular disease may initially report exertional dyspnea, fatigue, orthopnea, or symptoms of cor pulmonale.

DIF:    Recall             REF:   p. 644            OBJ:   2

5. All of the following are examples of clinical conditions that can precipitate respiratory failure rapidly in patients with significant neuromuscular weakness except:

ANS:  D

Pulmonary edema, pneumonia, and mucous plugging are examples of clinical conditions that can precipitate respiratory failure rapidly in patients with significant neuromuscular weakness. Such patients may need observation of their respiratory status when they are in the hospital with these conditions
