Atelectasis is defined as the lack of gas exchange within alveoli, due to alveolar collapse or fluid consolidation. Banehollow, a 4-year old child, was rushed to the ER after swallowing several pieces of clay. After undergoing x-ray, the child is diagnosed with atelectasis of the right lung d/t to complete obstruction in the right bronchus. Stat surgery is to be done. Which of the following assessment findings would Nurse Bradwarden most likely find? Choose one answer.
a. tracheal shift to the left, breath sounds absent in the left lung, present in the left, hyperresonance percussion in the left lung Incorrect
b. tracheal shift to the left, breath sounds absent in both lung fields, dull percussion in the right lung Incorrect
c. tracheal shift to the right, breath sounds absent in the right lung, present in the left, dull percussion on the right lung Correct In atelectasis, fewer aerating alveoli are present and therefore have a lower pressure. Therefore, the trachea is slightly pushed by the healthy lung to the affected side, which contains less air and lesser pressure. Breath sounds are absent in the right lung because alveoli are not ventilated because air does not reach them. Breath sounds are present in the left lung because the alveoli are still ventilated as the bronchus is unobstructed. Dull percussion is elicited because the alveoli are collapsed and air is not present in the affected lung. (p. 473, Health Assessment and Physical Examination by Estes 3rd edition, 2006)
d. tracheal shift to the right, breath sounds absent in the right lung, present in the left, resonance percussion in the left lung Incorrect Incorrect
