A nurse is collecting data from a client. Which of the following findings should the nurse report to the charge nurse as an indicator of dehydration?

Skin tenting is a classic sign of dehydration. When the skin over the back of the hand or forearm is gently pinched and released, it returns slowly to its normal position in a dehydrated client because the interstitial fluid that normally gives skin its turgor has been depleted. This is a straightforward and reliable clinical indicator the nurse should promptly report. Red mucous membranes are not a sign of dehydration; dehydration typically causes dry, pale, or tacky mucous membranes rather than redness, which is more associated with inflammation or infection. A blood pressure of 178/90 mm Hg reflects hypertension, which is the opposite of what is expected in dehydration — dehydration reduces circulating volume and tends to lower blood pressure, producing hypotension and tachycardia. Jugular vein distention is a sign of fluid overload or right-sided heart failure, where excess venous pressure causes the neck veins to become visibly engorged. This finding is the opposite of dehydration, in which veins would be flat due to reduced circulating volume. Therefore, skin tenting is the only option consistent with volume depletion and should be reported as an indicator of dehydration.
