Which are early signs of dehydration in field conditions, and what actions should you take?

• A. Thirst, dry mouth, fatigue, dark urine; provide safe fluids, avoid overhydration, monitor
• B. Headache only
• C. Immediate IV fluids
• D. Do nothing

Answer: (A)

In the field, recognizing dehydration early hinges on noticing the body's prompts that fluids are running low. Thirst and dry mouth are immediate signals that you need fluids, while fatigue shows the body's energy and performance are being affected by reduced hydration, and dark urine indicates the kidneys are concentrating urine to conserve water. The best response is to provide safe fluids and monitor closely. Offer water or an oral rehydration solution in small, regular sips rather than a large amount at once to avoid stomach upset. This helps replenish fluids and electrolytes without overwhelming the system. Keep an eye on urine color and output as a simple gauge of improvement; as rehydration progresses, urine should become lighter and more frequent. Also watch for signs that would require more advanced care (dizziness, confusion, fainting, vomiting that prevents keeping fluids down, or no urination for an extended period); if those occur, seek medical support. Giving only an IV in a field setting isn’t appropriate for early signs, and doing nothing would let dehydration worsen.
