What are two significant differences between the first element of medical decision making, number of diagnoses and management options, and the second element of medical decision making, the amount and/or complexity of data?

What will be an ideal response?

Answers should include the following:
The first element of medical decision making, number of diagnoses and management options, addresses the physician's familiarity with the presenting problem and any need for diagnostic testing to discern the possible, probable, rule-out, or final diagnosis, or diagnoses.
The second element of medical decision making specifically addresses the amount and/or complexity of data to be reviewed during the collection of any clinical, laboratory, pathology, or radiology results.
