Which of the following is a dehydration sign and symptom listed in the material?

• A. Headache
• B. Dizziness
• C. Fatigue
• D. Thirst

Answer: (D)

Thirst is the body's direct signal that it needs more fluids and is typically listed as a dehydration sign and symptom. When you’re dehydrated, plasma osmolality rises and receptors in the brain trigger the urge to drink water, making thirst one of the earliest and clearest cues to rehydrate. While headache, dizziness, and fatigue can occur with dehydration, they are less specific and not the primary sign highlighted in the material. So thirst best fits the listed dehydration signs and symptoms.
