How many contacts can a single patient record have in relation to events?

How many contacts can a single patient record have in relation to events?

• A. multiple
• B. exactly one
• C. zero
• D. unknown

Answer: (A)

Relationship multiplicity in the data model shows that a patient can be linked to many contacts over time through events. A patient may have multiple events, each involving different contacts (like a physician, a nurse, a social worker, or family members). Because care interactions accumulate over time, there isn’t a fixed limit to how many contacts a single patient record can relate to via events—there can be multiple. That’s why the best answer is that it can be multiple. Saying exactly one would ignore the reality of ongoing care with several people involved, and zero would only apply if there were no events at all, which isn’t the general expectation for a patient’s history.
