A nurse in a community clinic is assessing an older adult client for manifestations of dehydration. Which of the following findings should the nurse expect?

A. Protruding eyeballs: Proptosis or bulging eyes is not associated with dehydration. This finding is more commonly related to conditions such as thyroid eye disease or orbital tumors and does not indicate fluid deficit in older adults. B. Hypothermia: Dehydration typically does not cause hypothermia. Older adults may have altered thermoregulation, but dehydration more commonly presents with other signs such as tachycardia, hypotension, or dry mucous membranes rather than low body temperature. C. Elevated blood pressure: Dehydration usually leads to decreased circulating volume, which often results in hypotension rather than hypertension. Elevated blood pressure is not a typical expected finding in fluid-deficient states. D. Furrows in the tongue: Dry mouth and deep furrows on the tongue are classic signs of dehydration. Reduced fluid intake or excessive fluid loss causes mucous membranes to become dry, and the tongue may appear cracked or furrowed.
