Section 1: Chronicles Database Architecture &
Data Structures (Questions 1–10)
1. Which of the following correctly describes the
structural hierarchy of Epic’s Chronicles
database from the highest level of organization
to the most granular?
A) Record, Master File, Item, Contact
B) Master File, Record, Contact, Item
C) Contact, Record, Master File, Item
D) Master File, Contact, Record, Item
Answer: B) Master File, Record, Contact, Item
Rationale: Chronicles is structured like a filing
cabinet. The Master File (INI) represents the
,cabinet itself. The Record represents a specific
drawer or folder within that cabinet. The Contact
represents a specific dated entry or event (like
an encounter) within that folder. The Item
represents the specific data field (like blood
pressure or a name) within that contact.
2. An analyst needs to configure an item that
stores a patient's historical blood pressure
readings. Each time a new reading is entered,
the old value must be preserved to track trends
over time. Which "Add Type" must be configured
for this item? A) Single Response
B) No Add
C) Response Each Time
D) Add On Fly
Answer: C) Response Each Time
Rationale: The "Response Each Time" add type
creates a new contact or node every time data is
entered, allowing the system to store a historical
log of values over time. "Single Response" items
only store one value per record and overwrite the
previous data if a change is made.
3. When configuring a questionnaire, you want to
create a field where users select exactly one
option from a hardcoded list of values (e.g.,
,"Yes", "No", "Unknown"). Which Data Type
should you select?
A) Free Text
B) Category
C) String
D) Word Processing
Answer: B) Category
Rationale: Category data types are used for strict
lists of predetermined values, such as dropdown
menus or radio buttons. Free Text and String
allow for unstructured typing, while Word
Processing is used for long, multi-line narratives.
4. What unique three-letter identifier is assigned
to every Chronicles Master File to distinguish it
across the database ecosystem?
A) IDN
B) INI
C) CID
D) MRI
Answer: B) INI
Rationale: Every Master File in Epic is
designated by a unique three-letter code known
as the INI (e.g., EPT for Patient, EMP for User,
DEP for Department).
, 5. In Epic's data dictionary, an item's "Response
Type" dictates how many values can be stored in
that item for a single contact. If an item needs to
hold a list of multiple current diagnoses for a
single encounter, which Response Type is
required? A) Single
B) Multiple
C) Related
D) Continuous
Answer: B) Multiple
Rationale: A "Multiple" response type allows an
item to hold more than one value on a single
contact line (e.g., a list of symptoms or
diagnoses). A "Single" response type restricts
the item to only one value per contact.
6. Which Chronicles feature allows two separate
items to be linked together line-for-line, ensuring
that a value in the first item directly corresponds
to a value in the second item (such as a
medication name and its associated dosage)?
A) Response Each Time
B) Related Response Type
C) Category Value Control
D) Item Overlap
Answer: B) Related Response Type
