CNA - Certified Nursing Assistant Aging Process 1

Question 1

Which of the following is a normal age-related change in the respiratory system?

Accepted Answer

Decreased elasticity of lung tissue

Answer

Aging causes the lungs to lose elasticity, making it harder to fully expand and contract. This reduces respiratory efficiency and reserve capacity, which is a normal, expected change — not a disease process.

Question 2

A normal skin change associated with aging is:

Accepted Answer

Decreased subcutaneous fat

Answer

With aging, subcutaneous (under-skin) fat decreases, reducing cushioning and insulation. This makes elderly residents more vulnerable to cold temperatures and pressure injuries.

Question 3

Which change in the urinary system is considered a normal part of aging?

Accepted Answer

Decreased ability to concentrate urine

Answer

The aging kidney loses some ability to concentrate urine, which means elderly residents may produce more dilute urine and are at greater risk for dehydration despite adequate fluid intake.

Question 4

An elderly resident reports that food does not taste as good as it used to. The CNA should recognize this as:

Accepted Answer

A normal age-related decline in taste sensation

Answer

The number of taste buds decreases with age, and the sense of smell also diminishes, both of which reduce the ability to taste food. This is a normal aging change that can affect appetite and nutritional intake.

Question 5

Which of the following is a normal change in the nervous system related to aging?

Accepted Answer

Slowed response time and reaction speed

Answer

Aging slows nerve conduction velocity and reduces the speed of neural processing, resulting in slower reaction times. This is a normal change and contributes to increased fall risk in elderly residents.
