Informatics
Nursing Informatics Study Guide (NCLEX Review)
⭐ Nursing Informatics
Definition:
Uses technology and information to:
Communicate
Manage knowledge
Reduce errors
Support clinical decision-making
Remember:
Technology + Nursing Knowledge = Better Patient Care
Florence Nightingale
First nurse to use data (1850s)
Used statistics to improve sanitation
ANA recognized Nursing Informatics as a specialty in 1992
⭐ Simulation
Definition
A realistic clinical scenario used for learning without harming real patients.
Benefits
Safe place to practice skills
Make mistakes without harming patients
Improves:
Critical thinking
Clinical decision making
Communication
Leadership
Confidence
Allows practice using:
Electronic Health Records (EHR)
Medication administration
Provider communication
NCLEX Tip
Simulation allows students to make errors without causing patient harm.
⭐ Clinical Decision Making
A continuous process of:
Assess the patient
Identify the priority problem
Choose evidence-based interventions
Evaluate outcomes
⭐ Clinical Information System (CIS)
A computerized system used by healthcare providers to access patient information.
Examples:
Electronic Health Record (EHR)
Barcode medication scanning
Provider order entry
Lab results
Documentation
Benefits
Instant access to information
Better communication
Faster diagnoses
Improves patient safety
Reduces duplicate paperwork
Improves medication reconciliation
⭐ Electronic Health Record (EHR)
A digital version of the patient's chart.
Contains:
Medical history
Diagnoses
Allergies
Medications
Lab results
Provider notes
Benefits
Better communication
Reduces medication errors
Faster documentation
Improves continuity of care
⭐ Clinical Pathways
Also called:
Care Maps
Integrated Care Pathways
Purpose:
Standardized evidence-based plans for specific diseases.
Benefits:
Better outcomes
Shorter hospital stays
Lower costs
More efficient care
⭐ HIPAA (Health Insurance Portability and Accountability Act)
Federal law protecting patient privacy.
Purpose:
Protect patient health information (PHI)
Prevent fraud
Maintain confidentiality
⭐ Protected Health Information (PHI)
Any information that identifies a patient.
Examples:
Name
DOB
SSN
Address
Medical history
Test results
Insurance information
⭐ HIPAA Rules
Privacy Rule
Protects all PHI.
Allows:
Patients can see their records.
Patients may request corrections.
Limits:
Who can view or share PHI.
Security Rule
Protects electronic PHI (ePHI).
Uses:
Passwords
Encryption
Secure systems
Cybersecurity safeguards
Breach Notification Rule
If unsecured PHI is exposed:
Notify affected patients
Notify HHS
Within 60 days
If PHI is encrypted → No breach notification required.
Enforcement Rule
Handled by:
Office for Civil Rights (OCR)
Can result in:
Investigations
Fines
Criminal charges
Jail time (serious violations)
⭐ HIPAA Violations
Examples:
Talking about patients with people not involved in care
Posting on social media
Texting PHI from personal phone
Taking patient pictures
Leaving charts open
Throwing away PHI improperly
⭐ Telehealth
Healthcare using technology.
Examples:
Video visits
Online appointments
Remote assessments
Benefits:
Increases access
Saves travel
Helps rural patients
Addresses nursing shortages
⭐ RN vs LPN
RN
Assesses patients
Develops care plans
LPN/LVN
Monitors patients
Reports changes
⭐ Smartphones in Nursing
Can be used for:
Drug references
Clinical decision support
Medical calculators
Never:
Text patient information
Take patient photos
Store PHI on personal devices
⭐ Meaningful Use of EHR
Purpose:
Improve patient safety
Improve efficiency
Encourage electronic prescribing (e-prescribing)
Benefits:
Better communication
Fewer medication errors
Better documentation
⭐ Medication Reconciliation
Compare current medications:
On admission
Transfer
Discharge
Every healthcare visit
Purpose:
Prevent medication errors
⭐ Medication Errors
Medication process:
Ordering
Transcribing
Dispensing
Administration
Most nursing errors occur during:
Administration
⭐ Barcode Medication Administration (BCMA)
Steps:
Scan patient armband
Scan medication barcode
Benefits:
Verifies the rights of medication administration
Prevents wrong patient
Prevents wrong medication
Prevents wrong dose
⭐ Documentation
Documentation should be:
Accurate
Complete
Timely
Objective
Purpose:
Legal record
Communication
Continuity of care
Patient safety
Poor documentation = Poor patient care
⭐ Remote Patient Monitoring (RPM)
Uses:
Wearable devices
Blood pressure monitors
Pulse oximeters
Glucose monitors
Smart watches
Monitors:
Heart rhythm
Oxygen saturation
Blood glucose
Vital signs
Falls
Activity
Benefits:
Early detection
Better chronic disease management
Faster provider notification
⭐ Health Literacy
Definition:
Patient's ability to:
Obtain
Understand
Use health information
Low health literacy leads to:
More ER visits
Less preventive care
Worse outcomes
Higher healthcare costs
⭐ Digital Health Literacy
Ability to use:
Patient portals
Health apps
Online information
Telehealth
Nurses should:
Use simple language
Speak slowly
Use teach-back
Encourage questions
Demonstrate skills
⭐ Smart Infusion Pumps
IV pumps with built-in medication safety software.
Benefits:
Calculates infusion rates
Alerts for unsafe doses
Reduces medication errors
Never override alerts unless clinically appropriate.
