Understanding Age-Related Skin Changes
As people age, the skin's elasticity naturally decreases due to a reduction in collagen and elastin fibers, as well as a loss of subcutaneous fat. This process, known as senile elastosis, makes the skin on areas like the hands and forearms less reliable for assessing fluid balance. The pinched skin on these sites will often 'tent' or remain elevated for a prolonged period, regardless of the person's hydration level, giving a false-positive reading for dehydration. For this reason, nurses must adapt their assessment techniques for geriatric patients to ensure accurate results and appropriate care.
Reliable Sites for Skin Turgor Assessment in Older Adults
When assessing skin turgor in the elderly, a nurse should choose sites that are less susceptible to natural age-related changes. These areas offer a more reliable indicator of the client's actual hydration status. The most recommended sites include:
- The Sternal Area (Breastbone): The skin over the sternum tends to retain its natural elasticity longer than skin on the extremities. To assess, the nurse should gently pinch a fold of skin below the clavicle and over the sternum. If the skin returns quickly to its normal position, it is a sign of adequate hydration. Prolonged tenting suggests potential dehydration.
- The Forehead: The skin on the forehead also maintains its integrity well into old age. While it may not be as prominent an assessment site, it can be used as a secondary check. The nurse can gently pinch the skin on the forehead and observe its recoil. This site is particularly useful for bed-bound patients.
- The Clavicle (Collarbone): Another reliable site for assessment is the skin just below the clavicle. The skin here is firm and not prone to the same degree of natural slackness as the back of the hand. The nurse can pinch a fold of skin and evaluate its rebound speed, similar to the sternal assessment.
Proper Technique for Assessment
Conducting a skin turgor assessment requires a specific, careful technique to ensure reliability and patient comfort. Here is a step-by-step guide:
- Select the Site: Choose one of the reliable sites, such as the sternum or clavicle. Avoid the back of the hand, which is not a credible site for elderly clients.
- Gently Pinch: Use your thumb and forefinger to gently pinch a small fold of skin. Do not cause discomfort to the client.
- Observe Recoil: After holding the skin for a few seconds, release it and observe how quickly it returns to its normal state.
- Interpret the Results: A rapid return indicates good skin turgor and likely adequate hydration. Slower recoil or "tenting" for an extended period suggests decreased skin turgor, which can be an indicator of dehydration, though other signs should also be considered.
Assessment Sites: Elderly vs. Younger Adults
To highlight the importance of site selection, the following table compares the recommended assessment locations for different age groups.
| Assessment Site | Young/Middle-Aged Adults | Elderly Clients (over 65) |
|---|---|---|
| Back of Hand | Reliable | Unreliable (due to natural aging) |
| Forearm | Reliable | Less Reliable (due to natural aging) |
| Sternal Area | Reliable | Reliable (less affected by aging) |
| Forehead | Less common | Reliable (less affected by aging) |
| Clavicle (Below) | Reliable | Reliable (less affected by aging) |
| Abdomen | Reliable | Less Reliable (due to changes in fat distribution) |
Other Indicators of Dehydration in the Elderly
While skin turgor can be a helpful tool when used correctly, it is never the only sign to look for. In the elderly, a nurse must also consider other, often more significant, indicators of dehydration. These include:
- Dry mucous membranes (tongue, mouth, lips)
- Sunken eyes
- Decreased urine output and dark, concentrated urine
- Changes in mental status, including confusion or dizziness
- Complaints of fatigue or weakness
- Rapid, thready pulse
- Low blood pressure
- Decreased appetite
The Holistic Approach to Hydration Assessment
Proper hydration assessment in an elderly client is a multi-faceted process that goes beyond a simple skin turgor check. A skilled nurse synthesizes information from multiple sources, including the reliable skin turgor sites, observation of other clinical signs, and patient history. This holistic approach ensures that dehydration is identified promptly and treated effectively, preventing more serious health complications. It is also important to remember that thirst sensation often diminishes with age, making it a poor indicator of hydration needs in older adults.
For a deeper understanding of comprehensive geriatric assessment techniques, including skin and hydration status, nurses can refer to reputable professional resources. One such resource is the Geriatric Nursing textbook by the American Nurses Association, which details evidence-based practices for caring for older adults.

Conclusion
In summary, when assessing skin turgor in the elderly client, a nurse must move beyond the traditional assessment sites used for younger individuals. By focusing on areas like the sternum, forehead, and clavicle, which are less affected by natural aging, and combining this observation with other clinical signs, a more accurate picture of the client's hydration status can be obtained. This vigilance is a cornerstone of quality senior care and helps prevent health complications associated with dehydration.
