Answer to Question 1

Correct Answer: 3, 4, 5
Cl concentration in sweat is analyzed to confirm the diagnosis of cystic fibrosis. In CF, the Cl concentration is > 70 mEq/L. ABGs and oxygen saturation levels show hypoxemia. Pulmonary function studies reveal reduced total lung capacity. Patchy infiltrates on chest x-ray would be associated with pneumonia. Mediastinal shift on chest CT scan is consistent with a tension pneumothorax.

Answer to Question 2

Correct Answer: 2, 3
For huff coughing, the patient should be instructed to inhale deeply while leaning forward and to exhale sharply with a huff sound, to help keep airways open while mobilizing secretions. Coughing twice is part of the controlled coughing technique. Inhaling through the nose with the mouth closed is part of the pursed-lip technique. Placing one hand on the abdomen and the other on the chest is part of the diaphragmatic breathing technique.
