Answer to Question 1

A
Feedback:
Ipratropium is an anticholinergic administered via inhalation to produce bronchodilation without systemic effects. It is generally used as an adjunct to a b2-adrenergic agonist. Montelukast decreases the inflammatory response by antagonizing the effects of leukotrienes. Cromolyn prevents release of histamine from sensitized mast cells. Theophylline provides for continuous airway relaxation.

Answer to Question 2

B
Feedback:
Pulse oximetry is a useful tool for determining the extent of hypoxia. It can be used by the nurse for continuous or intermittent monitoring. Pulmonary function testing measures respiratory flow and lung volumes and is indicated for asthma, cystic fibrosis, and chronic lung disease. Peak expiratory flow testing is used to monitor the adequacy of asthma control. Chest radiographs can show hyperinflation, atelectasis, pneumonia, foreign bodies, pleural effusion, and abnormal heart or lung size.
