Severe dehydration is indicated by which symptom?

• A. VERY dry mouth
• B. Extreme thirst
• C. Rapid heart beat
• D. Confusion

Answer: (A)

Severe dehydration is signaled most clearly by a very dry mouth because as body fluids drop, saliva production dwindles and the mucous membranes become noticeably parched. This direct, observable cue reflects a significant fluid deficit and is a practical, quick indicator in real-world settings like training or coaching. Extreme thirst can occur with dehydration but isn’t as specific to severe cases and can happen earlier in the process; a rapid heartbeat can be caused by multiple factors and isn’t unique to severe dehydration; confusion tends to appear later when dehydration is already advanced and electrolytes are imbalanced. So, the presence of a very dry mouth best points to severe dehydration in this context.
