Answer to Question 2
C
Atelectasis is the collapse of alveoli. In atelectasis, secretions block a bronchiole or a bronchus, and the distal lung tissue (alveoli) collapses as the existing air is absorbed, producing hypoventi-lation. If the client were suspected of having atelectasis, the nurse would expect diminished breath sounds in the area of hypoventilation.
Atelectasis may cause changes to the pulse; however, evaluating the pulse will not help diagnose atelectasis.
Atelectasis may cause changes to the blood pressure; however, evaluating the blood pressure will not help diagnose atelectasis.
Bronchovesicular sounds are a mixture of bronchial and vesicular sounds. Bronchovesicular whooshing would not be an expected sound indicating atelectasis.
