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. Furrows in the tongue: Dehydration often causes dryness of the oral mucosa and the tongue, leading to prominent furrows or deep grooves. This is a common assessment finding in older adults because their thirst sensation is diminished, making them more prone to dehydration. B. Protruding eyeballs: Proptosis is not related to dehydration but rather to conditions like hyperthyroidism or orbital tumors. Dehydration instead may cause sunken eyes due to fluid volume loss. C. Elevated blood pressure: Dehydration typically leads to decreased circulating blood volume, resulting in low blood pressure or orthostatic hypotension rather than an elevation in blood pressure. D. Hypothermia: Dehydration more commonly causes fever or increased body temperature due to impaired thermoregulation. Hypothermia is not a usual manifestation of dehydration in older adults.
