Which statement indicates the need for further teaching about aging skin?

• A. The elasticity of the skin decreases with age.
• B. The collagen content of the skin increases with age.
• C. The underlying muscle and tissues become thinner with age.
• D. The older adult's skin can be easily torn in response to mechanical trauma.

Answer: (B)

Understanding how aging affects the skin includes knowing that collagen decreases, not increases, with age. Collagen and elastin fibers break down over time, and dermal thickness and subcutaneous fat tend to diminish. This reduces skin elasticity and strength. The option claiming collagen content increases with age contradicts these well-established changes, so it signals a misconception that needs teaching.

The other statements reflect true aging changes: elasticity declines, the underlying tissues tend to become thinner, and the skin is more easily torn with mechanical trauma. These align with expected physiological aging, so they don’t indicate a knowledge gap.
