A nurse is performing high-frequency chest compressions using a mechanical chest compression device for a child who has cystic fibrosis. Which of the following findings indicates the treatment has been effective?
The child develops a dry, hacking cough.
The child has increased nasal secretions.
The child has increased sputum production.
The child develops diminished breath sounds.
The Correct Answer is C
A. The child develops a dry, hacking cough: This suggests ineffective clearance of secretions and may indicate a need for further intervention.
B. The child has increased nasal secretions: Nasal secretions are not directly related to the effectiveness of high-frequency chest compressions in clearing pulmonary secretions.
C. The child has increased sputum production: Increased sputum production indicates that the
treatment is effectively mobilizing and clearing mucus from the airways, which is beneficial for a child with cystic fibrosis.
D. The child develops diminished breath sounds: Diminished breath sounds could indicate a complication such as atelectasis or pneumothorax and would not be an expected finding with effective high-frequency chest compressions.
