Certified Electronic Health Records Specialist
(CEHRS) Mock Examination – Comprehensive EHR
Practice Questions with Rationales
1. A patient presents at the front desk and states their legal name has changed since their last
visit. Which action should the EHR specialist take to maintain the integrity of the Master
Patient Index (MPI)?
A. Update the patient’s record immediately based on their verbal statement.
B. Create a new patient chart with the new name to ensure all future records are accurate.
C. Request legal documentation such as a marriage certificate or court order before
updating the name.
D. Inform the patient that their name cannot be changed in a legal health record once
established.
Correct Answer: C
Explanation: Maintaining data integrity within the Master Patient Index (MPI) requires
verifying legal identification to prevent duplicate records or identity errors. By requiring
legal documentation, the specialist ensures that the medical record remains a valid legal
document that accurately represents the patient’s identity. A common mistake is creating a
duplicate record or updating information without verification, which can lead to
fragmented care and billing complications.
,2. While documenting in a patient’s EHR, a provider realizes they have entered a note into
the wrong patient’s chart. What is the correct procedure for correcting this error?
A. Flag the note as erroneous, follow the facility’s amendment policy, and cross-reference
the correct chart.
B. Leave the note as is but write a new note in the correct chart.
C. Delete the entire note and start over in the correct chart.
D. Cut and paste the note into the correct chart and use white-out on the screen.
Correct Answer: A
Explanation: EHR integrity requires that errors are not simply deleted but are corrected
using a transparent audit trail that shows the original entry and the correction. This
process protects the legal validity of the record and ensures clinical staff do not rely on
inaccurate information during treatment. Candidates should avoid simply deleting
information, as HIPAA and legal standards require an ‘audit log’ of all changes to PHI.
3. A provider is using Computerized Provider Order Entry (CPOE) to prescribe a new
medication. The system displays an alert indicating a potential drug-allergy interaction. What
is the primary purpose of this EHR function?
A. To slow down the provider to ensure they are paying attention.
B. To automate the billing process for pharmacy services.
C. To provide Clinical Decision Support (CDS) to improve patient safety.
D. To fulfill the requirements of the facility’s marketing department.
,Correct Answer: C
Explanation: Clinical Decision Support (CDS) provides clinicians with knowledge and
person-specific information, intelligently filtered or presented at appropriate times, to
enhance health and healthcare. These alerts significantly reduce adverse drug events by
catching potential errors before the order is finalized. A common mistake is ignoring these
alerts (alert fatigue), which can lead to serious patient harm and liability.
4. According to the HIPAA Security Rule, which of the following is considered a technical
safeguard?
A. Locked doors to the server room.
B. Unique user identification and encryption.
C. Written policies regarding workstation use.
D. Background checks for all new employees.
Correct Answer: B
Explanation: Technical safeguards are the technology and the policy and procedures for
its use that protect electronic protected health information (ePHI) and control access to it.
Using unique IDs and encryption ensures that only authorized personnel can access and
interpret sensitive data. Candidates often confuse administrative safeguards (policies) or
physical safeguards (locks) with technical ones.
, 5. An EHR specialist is training new staff on the use of the patient portal. Which of the
following is a primary benefit of using a patient portal?
A. It allows the patient to edit their own clinical diagnoses directly.
B. It eliminates the need for the provider to document in the EHR.
C. It increases patient engagement and allows secure communication with the provider.
D. It provides a public forum for patients to discuss their health issues with others.
Correct Answer: C
Explanation: Patient portals enhance the patient-provider relationship by allowing
patients to view lab results, schedule appointments, and message their care team securely.
This transparency empowers patients to take an active role in their health management
and improves administrative efficiency. A common mistake is thinking portals are social
media platforms; they are secure, HIPAA-compliant extensions of the EHR.
6. Under the HIPAA Privacy Rule, a covered entity must provide a patient with access to their
PHI within how many days of the request?
A. 15 days
B. 60 days
C. 45 days
D. 30 days
Correct Answer: D
