Answer

To solve the question regarding the symptoms of altitude sickness, we need to identify which symptom does not belong to the list of common symptoms associated with altitude sickness. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand Altitude Sickness
Altitude sickness occurs when you cannot get enough oxygen from the air at high altitudes. It typically happens at elevations above 2,500 meters (8,200 feet).

### Step 2: Identify Common Symptoms
Common symptoms of altitude sickness include:
- Nausea
- Fatigue
- Headaches
- Heart palpitations

### Step 3: Analyze Each Option
1. **Nausea**: This is a common symptom of altitude sickness, characterized by a feeling of sickness and the urge to vomit.
2. **Fatigue**: This refers to extreme tiredness and weakness, which is also a symptom of altitude sickness.
3. **Heart Palpitations**: This involves a racing or pounding heart, which can occur at high altitudes due to reduced oxygen levels.
4. **Hyperoxia**: This term refers to an excess of oxygen in the tissues, which is not a symptom of altitude sickness. In fact, altitude sickness is associated with a lack of oxygen (hypoxia), not an excess.

### Step 4: Determine the Correct Answer
Based on the analysis, the symptom that does not belong to the list of altitude sickness symptoms is **hyperoxia**.

### Final Answer
The correct answer is **hyperoxia**.
