Which description BEST represents the physical examination technique used to assess tissue hydration in the hand?

• A. Pinch and lift the skin and determine the time for the skin to return to normal.
• B. Push into the skin and determine the time for the skin to return to normal.
• C. Measure the surface temperature over the volar aspect of the wrist.
• D. Obtain volumetric measurements on each arm and compare displacement measures.

Answer: (A)

Skin turgor is the indicator used to assess tissue hydration. When you pinch and lift a fold of skin, the skin should rise briefly and then rapidly return to its flat shape if hydration and tissue elasticity are adequate. If the person is dehydrated or has reduced tissue turgor, the skin tents and takes longer to snap back, signaling diminished hydration in the skin and underlying tissues. This direct assessment of how quickly the skin recoil occurs is the most specific way to gauge hydration status in the hand. Pushing into the skin and watching for rebound is less reliable because the amount of pressure, skin thickness, and local edema can alter the response, making it harder to interpret. Measuring surface temperature reflects perfusion rather than hydration, and volumetric limb measurements gauge edema, not the skin’s hydration status.
