<s>[INST] You are working with a dataset about patients' medical information. Your code must use the `snake_case` naming convention,

Create a functional programming approach to filter the dataset where a patient's `blood_pressure` is greater than or equal to 130 AND their `cholesterol_level` is greater than or equal to 240. 

Before filtering, create a sample dataset with 10 entries meeting the requirements.

```python
# bool: high_blood_pressure = blood_pressure >= 130
# bool: high_cholesterol = cholesterol_level >= 240
```

```python
# Define the filter using a lambda expression
filter_clinical_criteria = lambda dataset: filter(lambda patient: patient['blood_pressure'] >= 130 and patient['cholesterol_level'] >= 240, dataset)
```

Here is what the filter condition looks like:

```python
# Define the boolean variables for blood pressure and cholesterol level
def define_these_variables(patient):
    
    # Define the variable high_blood_pressure
    patient["high_blood_pressure"] = blood_pressure_over_threshold(patient)
    
    # Define the variable high_cholesterol
    patient["high_cholesterol"] = cholesterol_over_threshold(patient)
    
    return patient

# Function to check if blood pressure is above 130
def blood_pressure_over_threshold(patient):
    return patient["blood_pressure"] >= 130

# Function to check if cholesterol level is above 240
def cholesterol_over_threshold(patient):
    return patient["cholesterol_level"] >= 240
```

How would I implement this?[/INST]
