- QUESTION 17 Lungs: With age, lung function becomes "less efficient." Which one does not explain why? Lung tissue becomes more "elastic" resulting in less expansion. There is a decrease in "reserve capacity" that affects stamina. There is a decrease in the number of airs sacs for oxygen transport. Muscles in the rib cage become weaker and reduce contraction.Question 1 When teaching parents what to do if their asthmatic child is in respiratory distress, the nurse would include all of the following EXCEPT: Question 1 options: Seek immediate medical attention if the child is in respiratory distress Do not allow the child to exert themselves Expose the child to cold fresh air to help with breathing Administer Ventolin 2 - 4 puffs every 15 - 20 minutesQuestion 27 in which bronchial and pulmonary disease do tubercles encapsulate bacteria, resulting in lung elasticity being reduced?
