Answer to Question 1

ANS: A
Usually the signs of pneumothorax are nonspecific. Tachypnea, tachycardia, dyspnea, pallor, and cyanosis are significant signs and symptoms and are indicative of respiratory distress caused by pneumothorax. If the bronchial tubes were dilated, the child would have decreased work of breathing and would most likely be asymptomatic. Carbon dioxide retention is a result of the chronic alveolar hypoventilation in CF. Hypoxia replaces carbon dioxide as the drive for respiration progresses. Increased viscosity would result in more difficulty clearing secretions.

Answer to Question 2

ANS: B
One of the only adverse effects of DNase is voice alterations and laryngitis. DNase is given in an aerosolized form, decreases the viscosity of mucus, and is safe for children younger than 12 years.
