The nurse is teaching a client who is newly diagnosed with asthma. The nurse explains that air is trapped in the alveoli due to:
1. the release of antihistamines in the body.
2. inflammation of the airways.
3. decrease of the production of mucus.
4. shortening of the expiratory phase of ventilation.
Answer: 2
1. In response to a trigger, the body produces histamines, which causes inflammation.
2. The release of histamines causes inflammation of the airways, which decreases the lungs' ability to move air in and out.
3. The production of mucus is increased and further narrows the airways.
4. The expiratory phase increases in an attempt to remove trapped air.
