LVN Comprehensive Study Guide: Legal/Ethical Nursing, End-of-Life Care, and Neurocognitive Disorders
The Structure and Function of the Legal System in Nursing
The practice of a Licensed Practical/Vocational Nurse (LPN/LVN) is governed by a complex framework of legal principles, established laws, moral standards, and ethical principles. Every state possesses specific nurse practice acts that establish the obligatory minimum standards for care. It is imperative that nurses act within their designated scope of practice; failing to meet established standards of care can lead to legal liability and the permanent loss of a nursing license.
The legal system is divided into two primary categories: criminal law and civil law. Criminal law involves conduct offensive to society as a whole and deals with public offenses such as robbery, murder, or assault. The fundamental purpose of criminal law is to punish and deter future crime, with cases resolved by a finding of guilt or innocence. Conversely, civil law addresses conduct that violates the rights of an individual rather than society at large. The purpose of civil law is to make the aggrieved person whole again, typically through accountability, innocence findings, or monetary settlements.
Negligence and Malpractice in Clinical Practice
Negligence is defined broadly as the absence of due care or general careless actions that any person might commit. Malpractice, however, is a professional level of failure. It is defined as the failure to meet a legal duty that subsequently causes harm to a patient. While negligence can be attributed to nurses or unlicensed assistive personnel, malpractice is reserved for professionals such as nurses and doctors. Examples of negligence include medication errors, patient falls, and equipment injuries. Malpractice scenarios often involve professional failings such as failing to report changes in a patient's status or performing a clinical procedure incorrectly. Total accountability is required for malpractice claims.
Statistical data indicated that the most common areas for litigation include labor and delivery cases, accounting for , surgery at , and emergency room medicine at . Critically, the most common factor leading to litigation across all areas is communication failure. Nurses should be familiar with legal terminology, such as assault (an intentional threat to cause harm without physical contact) and battery (unlawful touching without informed consent). Civil battery, sometimes called technical battery, can occur even if the intent was not to harm. Libel refers to malicious or untrue written statements, while slander refers to the same via spoken words. Defamation is the overarching term for statements that injure a person's reputation.
Legal Relationships, Advocacy, and Standards of Care
Accountability is defined as being responsible for one's own actions; this accountability gives rise to a legal duty. Liability is the legal responsibility itself. At the moment a nurse accepts a patient assignment, a legal relationship is initiated, establishing a duty to provide care at the expected level of expertise. In this role, the nurse also functions as an advocate — one who defends or pleads a cause on behalf of another.
There are several preventable omissions in nursing that frequently lead to legal issues. These include failures to collaborate with the health care team, failures to clarify interdisciplinary orders, failures to ask for or offer assistance, and the failure to utilize evidence-based performance. Furthermore, failing to communicate information to families, failing to limit overtime, or failing to adequately staff a unit with appropriately credentialed personnel are significant risks.
Standards of care define which acts are required, permitted, or prohibited. The legal test for determining if a standard was met involves comparing the nurse's actions with those of a reasonably prudent nurse of similar education and experience. Breaches of care are often categorized into practice failures (such as improper assessments, medication errors, or failing to honor advance directives), monitoring failures (failing to report deteriorating signs or detect pressure ulcers), and communication failures (timely documentation or failing to report abuse). A landmark legal case, Darling v Charleston, established the precedent that nurses are liable for failing to report a deteriorating patient, a standard now adopted by almost every state. In the legal world, care is not considered given if it was not charted; documentation serves as a nurse's primary legal protection.
Patient Rights and Informed Consent
In 1972, the American Hospital Association (AHA) developed the Patient's Bill of Rights, which was later updated in 2003 as The Patient Care Partnership. The Patient Self-Determination Act (PSDA) of 1990 requires that institutions receiving federal funding maintain written policies regarding advance directives. Patients have the right to access healthcare without prejudice, to be treated with dignity, to maintain privacy and confidentiality, and to receive complete information about their condition. They also have the right to accept or refuse treatment and participate in decision-making. Conversely, patients have responsibilities, including providing accurate medical information and participating in their treatment planning.
The doctrine of informed consent requires full disclosure of all facts a patient needs to make an intelligent decision regarding invasive treatments. Consent requirements dictate that the patient must be at least years old (with exceptions for marriage, court-approved emancipation, or service in the armed forces) and of sound mind, meaning they are not impaired by drugs or alcohol. While physicians and NPs are responsible for providing the information and disclosure, the nurse's role in informed consent is limited to acting as a witness to the signature only. The nurse should never be the one to provide the medical information; doing so creates legal liability. Patients may withdraw or limit consent at any any time.
HIPAA and the Protection of Health Information
The Health Insurance Portability and Accountability Act (HIPAA) of 1996 sets strict rules on who has permission to access health information and assigns penalties for wrongful disclosure. Protected Health Information (PHI) includes 18 specific identifiers: names, geographic locations smaller than a state (zip codes, cities, counties), dates (admission, discharge, death, and all ages over ), telephone numbers, fax numbers, email addresses, social security numbers, and medical record numbers. It also includes health plan beneficiary numbers, account numbers, license numbers, vehicle identifiers, device serial numbers, URLs, IP addresses, biometric identifiers (such as fingerprints), full face photographs, and any other unique identifying code.
Best practices for maintaining confidentiality include holding discussions in private rooms rather than elevators, closing doors during procedures, and destroying report sheets before leaving the worksite. Responsibility for confidentiality does not end at the shift change. Regarding social media, many nurses falsely believe that posted content is private or easily deleted. However, any violation of social media policies can lead to termination and nursing board sanctions. Nurses are also mandated reporters; under the Child Abuse Prevention Treatment Act of 1973, failing to report suspected abuse can result in fines or imprisonment. Acting in "good faith" protects the nurse from liability during these reports.
Insurance, Disciplinary Processes, and Advance Directives
Nurses should maintain professional liability insurance. Two types exist: claims-made policies, which protect when a claim is made while the policy is active; and occurrence-basis policies, which protect against claims for events during the policy period, even after it ends. Disciplinary defense insurance is also available to provide legal representation if a nurse is brought before a licensing board. Potential sanctions against a license include letters of reprimand, probation with stipulations, mandated diversion programs for substance abuse, suspension, or total revocation.
Advance directives are signed, witnessed documents that provide instructions if a patient becomes unable to make decisions. The two basic types are living wills and durable power of attorney for healthcare. A living will directs treatment in the event of terminal illness, whereas a durable power of attorney designates a specific agent or proxy to make decisions. For these to be enforceable, the patient must be legally incompetent. Termination of competency is determined by a judge, while decisional capacity is determined by a physician. Do-Not-Resuscitate (DNR) orders are written by physicians after family consultation; once written, the nurse has a legal duty to follow them. Historically, cases like Bouvia v Superior Court and Cruzan v Director, MO Dept of Health have upheld the right to refuse medical treatment or lifesaving hydration.
Ethical Principles in Nursing Practice
Ethics are values that influence behavior and feelings regarding right and wrong. Fundamental principles include respect for people (viewing life as sacred), autonomy (freedom of personal choice), beneficence (doing good), and nonmaleficence (doing no harm). Justice refers to the concept of fairness and the equal right to nursing interventions. Ethical dilemmas are situations where there is no clear right or wrong answer. To resolve these, nurses must identify the problem, gather info, consider ethical principles, and then act.
The ANA position on practitioner-assisted suicide (PAS) is that it is not consistent with the philosophy of nursing due to the duties of beneficence and nonmaleficence. While patients have a right to refuse treatment, a nurse may only refuse to assist with procedure that conflict with moral beliefs (like abortion) provided they do not abandon the patient. A nurse may never refuse care based on a patient's diagnosis or lifestyle, such as HIV status or sexual orientation.
Sentinel Events and Root Cause Analysis
A sentinel event is a safety event unrelated to the natural course of a patient's illness that results in death, permanent harm, or severe temporary harm. These events signal systemic problems and must be reported to The Joint Commission (TJC). "Never Events" are a subset of these that are considered preventable and unambiguous medical errors, such as surgery on the wrong body part, leaving foreign objects in a patient, or Stage 3 or 4 pressure ulcers acquired after admission.
When a sentinel event occurs, a Root Cause Analysis (RCA) must be performed. RCA is a tool that identifies contributing factors and systemic faults rather than individual blame, often using the "Five Whys" method. An RCA must be initiated within hours and completed within days. Failure to comply can place a facility on "Accreditation Watch." Nurses assist by stabilizing the patient, notifying supervisors, and completing accurate incident reports. Incident reports are internal quality improvement tools; they are not part of the medical record, and nurses should never document in the medical record that an incident report was filed.
Loss, Grief, and Dying
Loss occurs when an aspect of the self is no longer available. Grief is the pattern of physical and emotional responses to that loss. Maturational loss results from normal transitions (leaving home, menopause), while situational loss occurs suddenly (job loss, sudden death). Grief work is the process of adapting to these changes. Anticipatory grief involves preparing for a loss before it happens. Complicated grief, or dysfunctional grieving, occurs when responses are delayed, exaggerated, or masked.
Major theories of grief include Kübler-Ross's 5 Stages: Denial, Anger, Bargaining, Depression, and Acceptance. Bowlby's Phases of Mourning include Numbing, Yearning and Searching, Disorganization and Despair, and Reorganization. Worden's Tasks of Mourning require accepting reality, working through pain, adjusting to the environment, and finding an enduring connection. These stages are not sequential; patients may skip or repeat them.
Perspectives on death vary by age: children aged 0-5 believe death is reversible like sleep; those 5-9 realize it is final but think they can personally avoid it; and children 9-12 begin to understand their own mortality. Palliative care focuses on symptom relief and quality of life at any stage of illness, whereas hospice is specifically for the terminal phase. Signs of impending death include a slow, thready pulse, lowered blood pressure, Cheyne-Stokes respirations, mottling of extremities, and the "death rattle" (mucus in the throat).
Clinical Care and Postmortem Procedures
Nurses should prioritize physical care for the dying, including oral care every to hours and eye care for crusting. Postmortem care (Skill 25.1) involves donning clean gloves, closing the eyes and mouth, removing tubing (unless an autopsy is required), and placing the patient in a supine position with the head elevated to prevent discoloration. Valuables should be identified and given to the family or taped to the body for legal protection. Cultural practices vary: for example, Orthodox Jews typically oppose autopsies and prefer the body is not left unattended, while Roman Catholics may desire the Anointing of the Sick.
Neurocognitive Disorders: Delirium and Dementia
Neurocognitive disorders (NCDs) involve significant impairment in cognition. Delirium is a sudden, fluctuating decline in orientation and awareness, usually caused by medical conditions (UTI, hypoxia, medications) and is typically reversible. Dementia (Major NCD) is a progressive, irreversible cognitive decline that interferes with daily functioning. Alzheimer’s Disease (AD) is the most common form, characterized by amyloid plaques and neurofibrillary tangles in the brain. Other forms include Vascular Dementia (from strokes), Lewy Body Disease (featuring hallucinations and syncope), and Frontotemporal Dementia (affecting behavior and language).
Pharmacology for AD includes cholinesterase inhibitors such as Donepezil (Aricept), Rivastigmine (Exelon), and Galantamine (Razadyne), which increase levels of acetylcholine. Memantine (Namenda) is used for mid-to-late stage AD. These drugs are not curative but slow the decline. Nurses must avoid using Benzodiazepines in older adults as they increase oversedation and confusion. Antipsychotics in the elderly carry an increased risk of death.
Nursing care for NCD patients involves the Cognitive Developmental Approach (CDA), which adapts the environment to the patient. For patients with dementia, reality orientation may cause agitation; instead, nonconfrontational redirection and simple, direct statements (e.g., "Put your shirt on") are preferred. If a patient wanders or resists care, nurses should investigate unmet needs like pain or hunger rather than using physical restraints, which increase injury risk and anxiety.
Questions & Discussion
Q: What is the primary difference between delirium and dementia?
A: Delirium has a sudden onset and is typically reversible when the underlying cause is treated. Dementia has a slow, gradual onset and is chronic and irreversible.
Q: A patient with AD wanders during mealtimes. What is the priority intervention?
A: Consult the dietitian about providing high-protein, high-carb finger foods. This allows the patient to maintain nutrition while moving safely.
Q: What is the nurse's role in witnessing informed consent?
A: The nurse witnesses the signature only. They are not responsible for explaining the procedure; that is the physician's legal duty.
Q: How do most drugs used for Alzheimer's work?
A: They work as cholinesterase inhibitors, which block the breakdown of acetylcholine, thereby increasing its level in the brain to help memory and learning.
Q: When is a Stage 3 or 4 pressure ulcer considered a sentinel event?
A: It is considered a sentinel or "never" event when it is acquired after the patient has been admitted to the healthcare facility.
Q: If a nurse makes a mistake in charting, and the supervisor tells them to rewrite the notes, what should they do?
A: Refuse. Falsifying records is a licensure violation. The nurse should follow proper incident reporting procedures instead.
