Final answer:
The signs and symptoms of severe hypothermia include shivering and stumbling, no shivering and inability to walk, a mumbling and fumbling person, and lethargy and apathy.
Step-by-step explanation:
The signs and symptoms of severe hypothermia include:
- Shivering and stumbling: This is an early symptom of hypothermia where the body tries to generate heat through random muscle movements.
- No shivering, inability to walk: As hypothermia progresses, shivering may stop and individuals may experience difficulty walking due to muscle stiffness.
- A mumbling, fumbling person: Severe hypothermia can cause confusion and disorientation, resulting in mumbling and fumbling behavior.
- Lethargy and apathy: In advanced stages of hypothermia, individuals may become lethargic, lacking energy, and displaying apathy towards their surroundings.
