1. Telehealth has seen significant growth in recent years. Which of the following factors
contribute to the expansion of telehealth services? (Select All That Apply)
A. Increased prevalence of chronic diseases needing monitoring
B. Advances in mobile communication technology and high-speed internet
C. A decrease in the geriatric population requiring home-based care
D. Provider shortages in rural and underserved geographic areas
E. Changes in reimbursement policies by Medicare and private insurers
F. Patient demand for more convenient and accessible healthcare options
Correct Answer: A,B,D,E,F
Rationale: Telehealth expansion is driven by the necessity to manage chronic illnesses
more efficiently and the availability of robust digital infrastructure. Rural provider
shortages make remote consultation a critical alternative for health equity. Recent policy
shifts have also ensured that providers are compensated for virtual visits, matching the
growing patient desire for flexibility.
,2. A nurse is explaining the difference between a Personal Health Record (PHR) and an
Electronic Health Record (EHR) to a patient. Which statement is correct?
A. The EHR is managed solely by the patient, while the PHR is managed by the provider.
B. The PHR is a private, secure application through which an individual can manage and
share their health information.
C. The EHR contains less clinical data than a standard PHR.
D. Both records are essentially the same and are legally owned by the patient.
Correct Answer: B
Rationale: The Personal Health Record is designed to be patient-centric and patient-
controlled, allowing individuals to maintain their own health data. In contrast, an EHR is a
legal record created and maintained by healthcare providers during clinical encounters.
Understanding this distinction is vital for patient engagement and data management
strategies.
3. Which standard is primarily used for the exchange of clinical and administrative data
between software applications used by various healthcare providers?
A. ICD-10
B. HL7
C. CPT
D. LOINC
, Correct Answer: B
Rationale: Health Level Seven (HL7) provides a framework and related standards for the
exchange, integration, sharing, and retrieval of electronic health information. While ICD-10
is used for diagnosis coding, HL7 focuses on the messaging and communication between
different systems. This interoperability is essential for a cohesive healthcare delivery
system.
4. Which of the following are benefits of implementing a Computerized Provider Order Entry
(CPOE) system? (Select All That Apply)
A. Reduction in transcription errors
B. Immediate notification of drug-drug interactions
C. Elimination of the need for nurse verification
D. Improved turnaround time for pharmacy and laboratory orders
E. Increased clarity and legibility of clinical orders
Correct Answer: A,B,D,E
Rationale: CPOE systems significantly enhance patient safety by removing the risks
associated with illegible handwriting. They provide real-time clinical decision support,
such as alerting providers to potential allergic reactions or dosing errors. Furthermore, the
electronic nature of the orders streamlines communication between departments, though
nurses must still verify and implement orders per protocol.
