What is the primary clinical significance of assessing skin turgor of a patient?

Appeared in: BTSC 3 August 2025

Explanation

Skin turgor is a direct measure of the skin's elasticity, which reflects the interstitial fluid volume.
The primary purpose of this assessment is to quickly evaluate a patient's hydration status at the bedside.
When a patient is dehydrated, the skin loses its elasticity, causing it to return slowly to its normal position after being pinched—a sign known as 'tenting'.
This makes it a key indicator for identifying fluid volume deficit.

Option A: Skin temperature is assessed by palpation, typically with the back of the hand, to feel for warmth or coolness, which indicates changes in blood flow, not by pinching the skin.
Option C: The presence of a skin infection and erythema (redness) is determined by visual inspection and palpation for warmth, swelling, and tenderness, not by assessing elasticity.
Option D: Oxygen saturation is evaluated by observing skin color (for cyanosis), checking capillary refill time, and using a pulse oximeter. Skin turgor does not measure oxygen levels.

Clinical Relevance

Nursing practice connection: Use the key finding related to Clinical significance of skin turgor assessment to guide bedside assessment, documentation, and the next nursing action.
Assessing skin turgor is a fundamental nursing skill used for rapid screening of dehydration, a common and potentially serious condition.
It is especially important in vulnerable populations such as infants, children, and the elderly, who are at higher risk for fluid imbalances.
What if the patient is an older adult? In elderly patients, skin on the back of the hand or forearm naturally loses elasticity with age, which can give a false positive for dehydration. For a more accurate assessment in this population, the nurse should check turgor over the sternum or clavicle.

How to Approach the Question

First, identify the key term in the question: 'skin turgor'.
Recall the definition of skin turgor. It relates to the skin's elasticity and its ability to return to place after being pinched.
Connect this definition to its clinical purpose. The elasticity of the skin is directly affected by the amount of fluid in the tissues (hydration).
Evaluate each option based on this understanding.
Option A (temperature), C (infection), and D (oxygen) are all important skin assessments, but they are measured using different techniques (palpation for warmth, inspection for redness, observation for color/cyanosis).
Option B directly links skin elasticity to the assessment of hydration status, which is the correct primary significance of the test.
