A nurse is collecting data from a client who has dehydration. Which of the following findings should the nurse expect?

A. Sodium of 142 mEq/L is within the normal range and may not reflect dehydration, although hypernatremia can develop in more severe cases. B. Low urine output (oliguria, 20 mL/hr) is a common sign of dehydration, reflecting decreased renal perfusion due to fluid loss. This is an expected finding in a dehydrated client. C. Cool skin can occur in hypovolemic shock, but in mild to moderate dehydration, skin may be warm and dry rather than cool. D. Bradycardia is not typically associated with dehydration; instead, tachycardia is more common due to compensatory mechanisms for fluid loss.
