Which assessment method is considered unreliable in older adults?

The assessment of skin turgor is an important method used to evaluate hydration status, particularly in older adults. However, the reliability of this assessment can vary with age and skin changes. In older adults, the skin undergoes natural changes, including decreased elasticity and moisture content, which can affect the accuracy of skin turgor assessments.

When skin turgor is assessed at the sternum, it tends to be less reliable because the skin in this area is often older, more fragile, and has a higher likelihood of being influenced by factors such as pressure and position. Consequently, skin turgor measured here may not provide an accurate representation of a person's hydration status.

On the other hand, areas like the arm, leg, or back of the hand typically retain more reliable skin elasticity due to less significant skin aging effects, making them more appropriate sites for assessing hydration status. Thus, assessment of skin turgor at the sternum is recognized as unreliable in older adults due to these factors.
