Which statement about urine pH and skin damage is true?

• A. Acidic urine is more damaging to the skin than alkaline urine.
• B. Alkaline urine is more damaging to the skin than acidic urine.
• C. pH has no effect on skin damage.
• D. Neutral pH is most damaging to the skin.

Answer: (A)

The main concept is how urine pH affects skin irritation and damage in continence care. When urine is more acidic, the fluid can lower the skin’s surface pH further and disrupt the protective barrier of the outer skin layer. This makes the perineal skin more susceptible to chemical irritation and dermatitis, especially with moisture and prolonged exposure from incontinence. In this context, acidic urine tends to cause more skin irritation than alkaline urine, leading to increased redness, itching, and rash. Neutral pH is not the most damaging, and the idea that pH has no effect isn’t accurate, since pH directly influences how irritants interact with the skin.
