Fill in the blank:
As a result of hyperventilation, breath-holding time is _______________________.
While inspecting the patient’s chest, the nurse notes that the chest wall contracts on inspiration & bulges on expiration. From this assessment, she suspects:
1. What is the disorder of this 17-year-old student? Why?
2. Is this primarily a restrictive or an obstructive disorder? Why?
3. Write the formula for determining residual volume (RV).
4. Determine the residual volume (RV) before and after the use of the bronchodilator. a. RV before using the bronchodilator: b. RV after using the bronchodilator:
5. Why is expiration more difficult than inspiration in this person?
6. What does the change in pulmonary function after the bronchodilator therapy indicate?
7. Why does the bronchodilator exaggerate the tachycardia?
8. What causes the hypoxemia and the hypocapnia in this person?
9. A beta 2-adrenergic agent was prescribed for further use because it has less cardiostimulatory (beta1) effect. Based on your knowledge of beta1 and beta2 receptors, why is this a good suggestion?
10. An anticholinergic agent was also suggested as a possible nebulizer agent. How might this help the breathing problem?
