In asthma, spasm of the smooth muscle of the bronchi and bronchioles causes constriction, producing impaired respiratory function. Atopy, or development of an immunoglobulin E (IgE)mediated response, is inherited but
is not the only cause of asthma. Asthma is characterized by increased resistance in the airway. Asthma has multiple causes, including allergens, irritants, exercise, cold air, infections, medications, medical conditions, and endocrine factors. ANS: A

Nursing care of the child with a chest tube requires close attention to respiratory status; the
chest tube and drainage device used are monitored for proper function (i.e., drainage is not impeded, vacuum setting is correct, tubing is free of kinks, dressing covering chest tube
insertion site is intact, water seal is maintained, and chest tube remains in place). Movement
in bed and ambulation with a chest tube are encouraged according to the child's respiratory
status, but children require frequent doses of analgesia. Supplemental oxygen may be required in the acute phase of the illness and may be administered by nasal cannula, face mask, flow-by, or face tent. The child should be positioned on the left side, not the right. Lying on
the affected side if the pneumonia is unilateral ("good lung up") splints the chest on that side
and reduces the pleural rubbing that often causes discomfort. The chest tube should never be clamped; this can cause a pneumothorax. The chest tube should be maintained to the underwater seal at all times. What structural defects constitute tetralogy of Fallot?
a. Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
b. Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
c. Aortic stenosis, ventricular septal defect, overriding aorta, left ventricular hypertrophy
d. Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy
