I agree this ‘definition’ problem is outside of the scope of this list. But since you misused terms, I reacted.
In your example in words: - Observation 'Serum sodium = X’, 'Normal associated and stored Normal range for adult males:: Lower=A, Higher=B - Evaluation 1 'X is abnormal and lower than Lower bound A’ - Evaluation 2 'Patient System has a state of Hyponatrenomy’ - Evaluation 3 ‘Patient System has problem item on the Problem list Y’ - Evaluation 4 ‘Patient System has risk to have as possible diagnosis Z1, Z2, Z3’ - … -… - Evaluation N ‘Patient has diagnosis Z4’ I agree that just one single Observation is not enough to safely diagnose the patient. More is needed than that.
