AND CORRECT ANSWERS | ALREADY GRADED A+ | LATEST VERSION (JUST RELEASED)
Question 1
Which of the following is considered a primary benefit of Health Information System (HIS)
implementation regarding financial management?
A) Eliminating the need for all administrative staff.
B) Increasing the cost of patient care to boost revenue.
C) Improving cost control and reducing personnel costs and inventory levels.
D) Focus only on clinical outcomes while ignoring financial data.
E) Extending the time required for billing cycles.
Correct Answer: C) Improving cost control and reducing personnel costs and inventory
levels.
Rationale: HIS implementation streamlines administrative tasks, automates inventory
tracking, and optimizes staffing schedules. By reducing manual errors and redundant
processes, organizations can significantly lower personnel costs and manage inventory
more efficiently.
Question 2
How does a well-implemented HIS affect the quality of patient care?
A) By increasing the number of physical files nurses must carry.
B) By improving the timeliness and accuracy of patient care and administrative information.
C) By limiting the amount of information shared between doctors.
D) By replacing the need for bedside clinical assessment.
E) By ensuring that only historical data is available for decision-making.
Correct Answer: B) By improving the timeliness and accuracy of patient care and
administrative information.
Rationale: Electronic systems provide real-time access to patient data, which reduces delays
in treatment and minimizes the risk of medical errors caused by illegible handwriting or
missing paper charts, thereby directly enhancing the quality of care.
Question 3
Which of the following best describes the role of a Nurse Informaticist within a healthcare
organization?
A) Repairing broken hardware and computer monitors.
B) Verifying ownership of information, looking for information, and connecting parties.
C) Acting solely as a bedside nurse with no technology interaction.
D) Programming the core source code of the Electronic Health Record.
E) Limiting patient access to their own electronic health information.
Correct Answer: B) Verifying ownership of information, looking for information, and
connecting parties.
Rationale: Nurse Informaticists act as a bridge between clinical practice and IT. They
ensure data integrity (verifying ownership), facilitate data retrieval for evidence-based
, 2
practice, and ensure that different stakeholders (clinicians, IT, administration) are
communicating effectively.
Question 4
In Lewin’s Change Model, what occurs during the "Unfreezing" stage?
A) New habits are formed and solidified.
B) The actual movement or change is implemented.
C) Preparing the organization to accept that change is necessary by breaking down existing status
quo.
D) Archiving old data from the previous system.
E) Training users on the final version of the software.
Correct Answer: C) Preparing the organization to accept that change is necessary by
breaking down existing status quo.
Rationale: Unfreezing is the first stage of Lewin’s model. It involves preparing the mindset
of the staff, identifying the need for change, and overcoming resistance before the new
system or process is actually introduced.
Question 5
According to Lewin’s Change Model, which stage involves the solidification of the new state
after a change has been implemented?
A) Unfreezing
B) Changing
C) Refreezing
D) Analysis
E) Execution
Correct Answer: C) Refreezing
Rationale: Refreezing is the final stage of Lewin’s model. It involves stabilizing the change
so that it becomes the new standard operating procedure, ensuring that staff do not revert
to old, inefficient ways of working.
Question 6
In Shannon & Weaver’s Mathematical Model of Communication, what is the role of the
"Encoder"?
A) The person who ultimately receives the feedback.
B) The machine or person that converts the message into signals or binary data.
C) The physical medium used to send the message.
D) The source of noise that interrupts the message.
E) The person who translates the signal back into a message.
Correct Answer: B) The machine or person that converts the message into signals or binary
data.
Rationale: In this model, the encoder takes the message from the source and converts it into
, 3
a format suitable for transmission over a channel (such as a telephone converting voice into
electrical signals).
Question 7
What is the "Channel" in Shannon & Weaver's communication model?
A) The person providing feedback.
B) The machine used to decode the data.
C) The medium used to send the message.
D) The binary code used in the transmission.
E) The person who receives the message at the destination.
Correct Answer: C) The medium used to send the message.
Rationale: The channel is the physical or virtual path through which the encoded signal
travels from the transmitter to the receiver (e.g., airwaves, fiber optic cables, or a computer
network).
Question 8
Which step of Bloom’s Knowledge Discovery from Databases (DDD) involves cleaning and
removing noise from data?
A) Selection
B) Preprocessing
C) Transformation
D) Data Mining
E) Interpretation
Correct Answer: B) Preprocessing
Rationale: Preprocessing is the stage where raw data is cleaned. This includes handling
missing values, removing outliers, and ensuring the data is consistent and reliable before it
is transformed or mined.
Question 9
In Bloom’s DDD process, what is the primary goal of the "Data Mining" step?
A) Selecting which database to use.
B) Converting data into a common format.
C) Engaging software to uncover hidden patterns or inter-relationships within large data sets.
D) Evaluating the financial cost of the database.
E) Archiving the data for long-term storage.
Correct Answer: C) Engaging software to uncover hidden patterns or inter-relationships
within large data sets.
Rationale: Data mining is the specific application of algorithms to extract patterns from
data. It is the "discovery" phase where previously unknown relationships are identified.
