Answer to Question 1

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

Answer to Question 2

ANS: B
Arterial blood gases are the best way to monitor carbon monoxide poisoning. Pulse oximetry is contraindicated in the case of carbon monoxide poisoning because the PaO2 may be normal. The child should receive 100 oxygen as quickly as possible, not only if respiratory distress or other symptoms develop.
