Information Technology In Client Care — Use Of Information Technology In Client Care

Historical Context & Motivation

Healthcare has always depended on the accurate recording and rapid exchange of patient information, yet for most of the twentieth century those functions relied almost entirely on handwritten charts, verbal orders, and paper-based filing systems. Errors in transcription, illegible handwriting, and misplaced records contributed to preventable adverse events at alarming rates. The landmark 1999 Institute of Medicine report, To Err Is Human, estimated that between 44,000 and 98,000 Americans died each year due to medical errors, many of which were information-related. That revelation ignited a nationwide push to leverage information technology (IT) as a structural safeguard against human fallibility. Understanding this history helps practical nursing students appreciate why IT competency is now tested on the NCLEX-PN and why coordinated care depends on digital literacy.

This trajectory raises a central question for today's licensed practical nurse (LPN/LVN): how do the various forms of health information technology work together to improve client safety, promote efficient communication among members of the healthcare team, and ensure continuity of care across settings? The following sections address that question systematically, covering definitions, visual workflows, practical applications, and the legal and ethical considerations that every NCLEX-PN candidate must understand.

Core Principles & Definitions

Before exploring specific technologies, it is essential to anchor understanding in the foundational principles that guide the use of IT in client care. These principles are not merely theoretical; they directly inform the standards of practice that the National Council of State Boards of Nursing (NCSBN) expects practical nurses to uphold. Every technology discussed in this lesson can be evaluated against these core ideas, and NCLEX-PN questions frequently test whether candidates can apply them to realistic clinical scenarios.

Visual Explanation — The Health IT Ecosystem

The visual makes a crucial point: the EHR is not a single application but rather a hub that aggregates data from multiple specialized subsystems. When an LPN scans a medication barcode at the bedside, the BCMA system checks the scanned data against the provider's order stored in the EHR and generates an alert if there is a mismatch. Similarly, when a physician enters a computerized provider order entry (CPOE) order, the CDS engine runs that order through evidence-based rules—checking for drug interactions, duplicate therapies, and renal dose adjustments—before the order reaches the nurse's task list. Telehealth portals extend this ecosystem beyond facility walls, enabling remote monitoring of vital signs for clients with chronic conditions. The client's own data—from wearable devices, patient portal entries, and self-reported symptoms—flows upward into the record, closing the feedback loop and empowering shared decision-making.

How Health IT Works — Key Systems in Depth

Electronic Health Records (EHRs)

An electronic health record is a longitudinal digital record of a client's health information that is created, maintained, and accessed by authorized clinicians across multiple healthcare settings. Unlike the older electronic medical record (EMR), which typically resides within a single practice or facility, the EHR is designed for interoperability—meaning it can be shared with external providers, laboratories, pharmacies, and even the client through a patient portal. For the LPN, the EHR serves as both a documentation tool and a reference library: it stores assessments, care plans, medication administration records, laboratory results, and provider orders in a searchable, time-stamped format.

Computerized Provider Order Entry (CPOE)

CPOE systems allow authorized prescribers to enter medication, laboratory, and imaging orders electronically rather than writing them by hand. This eliminates ambiguity caused by illegible handwriting—a factor implicated in an estimated 7,000 deaths per year prior to widespread CPOE adoption. When a provider submits an order, the system cross-references it with the client's allergy list, current medications, diagnoses, and renal function to generate real-time alerts. The practical nurse receives the verified order on a task list, reducing the risk of transcription errors that plagued the era of verbal and handwritten orders.

Barcode Medication Administration (BCMA)

BCMA technology reinforces the five rights of medication administration—right client, right drug, right dose, right route, and right time. At the bedside, the LPN scans the client's identification wristband and then the barcode on the medication package. The system verifies that the scanned medication matches the active order in the EHR. If any parameter is incorrect, an alert fires immediately, preventing administration of the wrong drug or dose. Studies have demonstrated that BCMA reduces medication administration errors by as much as 50 to 80 percent when used consistently.

Clinical Decision Support (CDS) Systems

A clinical decision support system is software embedded within the EHR that provides clinicians with evidence-based guidance at the point of care. CDS may take the form of drug–drug interaction alerts, fall-risk scoring calculators, sepsis screening prompts, or evidence-based order sets for common conditions. For the practical nurse, CDS often manifests as pop-up alerts during charting or medication administration. While these alerts can occasionally cause 'alert fatigue' if they are too frequent or non-specific, their proper use represents a fundamental patient safety mechanism that the NCLEX-PN expects candidates to understand.

Telehealth & Remote Monitoring

Telehealth encompasses the use of video conferencing, mobile health applications, and remote patient monitoring (RPM) devices to deliver care across geographic distances. During and after the COVID-19 pandemic, telehealth utilization increased by more than 3,000 percent in some settings. LPNs may participate in telehealth by conducting intake assessments, monitoring transmitted vital sign data (e.g., blood glucose, blood pressure, pulse oximetry), and reinforcing client education. The legal scope of telehealth practice varies by state, and the NCLEX-PN tests awareness that the nurse must verify licensure requirements when care crosses state lines.

Detailed Breakdown — IT Applications Across the Care Continuum

The continuum diagram reveals that no phase of the client encounter is untouched by information technology. At admission, the client receives a barcoded identification band generated by the EHR, and scanned copies of signed consent forms are uploaded to the legal documents section of the record. During assessment, networked vital sign monitors transmit blood pressure, heart rate, temperature, and oxygen saturation readings directly into the flowsheet, eliminating manual transcription. Treatment relies on CPOE, BCMA, and CDS to keep medications and interventions safe. At discharge, e-prescribing sends prescriptions electronically to the client's chosen pharmacy, while discharge instructions and follow-up reminders populate the patient portal. Post-discharge, the Health Information Exchange (HIE) ensures that a specialist or home health nurse can access the same record, supporting seamless continuity of care.

Worked Example — Safe Medication Administration Using IT

The following scenario illustrates how multiple IT systems work together in a single medication administration event. Walk through each step as though you are the LPN at the bedside.

Strengths, Limitations & Ethical Considerations

While information technology has dramatically improved client safety and care coordination, it is not without limitations. An effective practical nurse recognizes both the strengths and the vulnerabilities of the IT systems they use daily. The NCLEX-PN expects candidates to weigh these factors when selecting the best nursing action in a scenario.

Legal Framework — HIPAA, Security, and Nurse Accountability

The legal landscape surrounding health IT is dominated by the Health Insurance Portability and Accountability Act (HIPAA) of 1996 and its subsequent amendments under the HITECH Act. HIPAA establishes three categories of safeguards—administrative, physical, and technical—that all covered entities and their business associates must implement. For the LPN, the most practically relevant provisions include the Privacy Rule, which governs who may access and disclose PHI, and the Security Rule, which specifies how electronic PHI (ePHI) must be protected through encryption, access controls, and audit logging.

It is also important to recognize how health IT intersects with emerging topics likely to appear on future NCLEX-PN examinations. Artificial intelligence (AI) and machine learning algorithms are increasingly embedded in clinical decision support tools, generating risk scores for sepsis, falls, and readmission. While these tools augment clinical judgment, the LPN must understand that they do not replace critical thinking; an algorithm's recommendation must always be evaluated in the context of the individual client's presentation. Similarly, blockchain technology and advanced encryption methods promise to enhance data integrity and interoperability in the coming decade. Staying current with these developments is part of the LPN's professional accountability, as outlined in the NCSBN's practice analysis.
