Physiological Changes with Aging
Physiological Changes with Aging ( 10 Questions)
A nurse is teaching a group of older adults about the respiratory system changes that occur with aging. Which of the following statements should the nurse include? (Select all that apply.).
These statements reflect the respiratory system changes that occur with aging, such as decreased respiratory muscle strength, decreased lung elasticity and recoil, decreased cough and gag reflexes, and decreased ciliary action and mucus production.
These statements reflect the respiratory system changes that occur with aging, such as decreased respiratory muscle strength, decreased lung elasticity and recoil, decreased cough and gag reflexes, and decreased ciliary action and mucus production.
These statements reflect the respiratory system changes that occur with aging, such as decreased respiratory muscle strength, decreased lung elasticity and recoil, decreased cough and gag reflexes, and decreased ciliary action and mucus production.
This is wrong because it states the opposite of what happens with aging. Vital capacity is the maximum amount of air that can be exhaled after a maximum inhalation.
These statements reflect the respiratory system changes that occur with aging, such as decreased respiratory muscle strength, decreased lung elasticity and recoil, decreased cough and gag reflexes, and decreased ciliary action and mucus production.
The correct answer is A, B, C, and E. These statements reflect the respiratory system changes that occur with aging, such as decreased respiratory muscle strength, decreased lung elasticity and recoil, decreased cough and gag reflexes, and decreased ciliary action and mucus production.
These changes can impair gas exchange, increase the risk of infections, and reduce exercise capacity.
Choice D is wrong because it states the opposite of what happens with aging.
Vital capacity is the maximum amount of air that can be exhaled after a maximum inhalation.
Residual volume is the amount of air that remains in the lungs after a maximum exhalation. With aging, vital capacity decreases and residual volume increases due to the loss of lung elasticity and airway closure.
This reduces the amount of fresh air that can enter the lungs and increases the amount of stale air that remains in the lungs.
