Final answer:
To check for skin turgor quickly and easily, pinch the skin on the posterior surface of the hand; it should swiftly return to normal, indicating adequate hydration.
Step-by-step explanation:
The quickest and easiest method for checking turgor, which is the skin's elasticity and an indicator of hydration, is to pinch the skin on the posterior surface of the hand. To do this, simply pinch the skin between two fingers and release it. The skin should quickly return to its normal position. If it stays pinched or takes a while to return to normal, this may indicate dehydration. This method is non-invasive and does not require any equipment, unlike drawing blood for analysis. Examining the patient's eyes or nails can provide some health information, but these are not specifically related to assessing turgor.
