You’re on Journey. During the expedition, and not all at the same time, a Learner complains of tingling lips, dizziness, is shaking, fatigued, irritable and anxious.
Another presents uncontrollable jerking movements, stiff muscles and is temporary confused.
Around midday, you notice a hiker in trouble; her skin colour is pale, she is sweating profusely, and after chatting to her, she tells you she feels dizzy and is nauseous.
You are the first aider on duty.
