**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the medical term that describes the condition of having an excess of potassium in the blood.

2. **Identifying Key Terms**: The key term here is "excess of potassium." We need to find a term that specifically refers to high levels of potassium in the blood.

3. **Analyzing the Options**:
- **Option 1: Hypercholesterolemia**: This term refers to high levels of cholesterol in the blood, not potassium. Therefore, this option is incorrect.
- **Option 2: Hyperkalemia**: This term specifically refers to high levels of potassium in the blood. This is the correct answer.
- **Option 3: Osteomalacia**: This condition is related to a deficiency of vitamin D and is not related to potassium levels. Thus, this option is also incorrect.
- **Option 4: Hyper excitability of nerves**: This condition is associated with low potassium levels (hypokalemia), not high levels.

4. **Conclusion**: Based on the analysis, the correct answer is **Hyperkalemia**, which is the medical term for the condition of having excess potassium in the blood.

**Final Answer**: Hyperkalemia
