How do you recognize and treat dehydration in a wilderness setting?

• A. Thirst, dry mouth, reduced urination; give large boluses of water; evac only if worse.
• B. Thirst, dry mouth, reduced urination; give small sips of water; avoid large boluses; consider electrolyte solutions; monitor for signs of heat illness; evac if symptoms persist or worsen.
• C. Only fatigue; rest in shade.
• D. Confusion and dizziness; use caffeinated drinks.

Answer: (B)

The main idea is recognizing dehydration early and rehydrating in a way that restores both water and electrolytes while avoiding methods that can cause harm in the backcountry. Early signs are thirst, dry mouth, and reduced urination, often with darker urine. In the wilderness, give small, frequent sips of fluids rather than large boluses. This keeps the stomach from getting overwhelmed and helps prevent vomiting or a dangerous shift in electrolytes. If available, use an oral rehydration solution or electrolyte-containing drinks to replace salts and minerals lost in sweat. While rehydrating, monitor for heat illness signs—dizziness, headache, confusion, nausea, or faintness—because dehydration increases the risk of heat-related problems. If symptoms persist or worsen, or if the person cannot keep fluids down or develops confusion, evacuate for higher-level care. Caffeinated drinks aren’t helpful here because they can act as mild diuretics and worsen dehydration, and resting alone without replacing fluids doesn’t address the problem.
