Which of the following is a symptom of dehydration?

Explanation:
Dehydration triggers the body's signal to restore fluid volume, and thirst is the direct cue the body uses to indicate the need for fluids. Thirst is a classic symptom because it reflects the body's effort to correct low fluid levels, often accompanied by a dry mouth and reduced urine output. Edema involves swelling from excess fluid in tissues, not loss of fluids. Cyanosis is a bluish discoloration from poor oxygenation, and wheezing is airway constriction—neither is a symptom of dehydration.
