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.).
“Your respiratory muscle strength may decrease as you age.”.
“Your lung tissue may become less elastic and more rigid over time.”.
“Your cough reflex and gag reflex may become weaker with age.”.
“Your vital capacity may increase and your residual volume may decrease as you age.”.
“Your ciliary action and mucus production may decrease with age.”.
Correct Answer : A,B,C,E
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.

Correct Answer is A
Explanation
The correct answer is A.“I may notice my hair becoming thinner and grayer as I age.” This statement reflects the common changes in hair that occur with aging, such as reduced melanin production, slower growth rate, and smaller hair strands.
Choice B is wrong because nails do not grow faster and stronger with age, but rather more slowly and may become dull and brittle.
Choice C is wrong because hair does not become more oily and curly with age, but rather drier and finer.
Choice D is wrong because nails do not become smoother and shinier with age, but rather yellowed and opaque.
Normal ranges for hair and nail growth vary depending on factors such as genetics, nutrition, health conditions, and environmental exposure.
However, some general estimates are:.
• Fingernails grow about 3 mm per month and toenails grow about 1 mm per month.
• Hair grows about 0.5 inches per month and loses about 50 to 100 strands per day.
• Hair color changes from about 30% gray at age 50 to about 50% gray at age 70.
Correct Answer is ["A","D","E"]
Explanation
The correct answer is A, D, and E.
Here is why:.
A. “You may experience dizziness when you stand up quickly.” This is true because aging causes the arteries and arterioles to become less elastic and less able to adjust the blood pressure quickly when the posture changes.This can lead to a drop in blood pressure when standing up, which can cause dizziness or fainting.
D. “Your blood vessels may become stiffer and narrower.” This is true because aging causes the walls of the arteries and arterioles to become thicker and stiffer, which reduces their compliance and increases the resistance to blood flow.This can lead to high blood pressure, atherosclerosis, and other cardiovascular diseases.
E. “Your heart may skip some beats or have extra beats.” This is true because aging causes changes in the electrical system of the heart, which can result in arrhythmias such as atrial fibrillation, premature ventricular contractions, or sinus bradycardia.These can cause irregular heartbeats that may be felt as palpitations or skipped beats.
B. “Your blood pressure may drop when you are resting.” This is false because aging does not cause a decrease in blood pressure at rest.
In fact, aging tends to increase the systolic blood pressure (the pressure when the heart contracts) due to the stiffening of the arteries.The diastolic blood pressure (the pressure when the heart relaxes) may remain normal or decrease slightly, resulting in a widened pulse pressure (the difference between systolic and diastolic pressures).
C. “Your heart may beat faster when you exercise.” This is false because aging does not cause an increase in heart rate during exercise.
In fact, aging tends to decrease the maximum heart rate that can be achieved during exercise due to the reduced responsiveness of the heart to adrenergic stimuli.The older heart also takes longer to recover after exercise.
Normal ranges for blood pressure are less than 120/80 mmHg for adults of any age.Normal ranges for heart rate are 60-100 beats per minute for adults of any age, but the maximum heart rate decreases with age according to the formula 220 minus age.
