Ethical Principles in Nursing, explained for the bedside and the exam
Written and reviewed by Dana Whitfield, RN, MSN · 4 min read · Updated September 2026
Short answer
The core ethical principles in nursing are autonomy, beneficence, non-maleficence, justice, fidelity, and veracity. Most clinical ethics questions, on the exam and at the bedside, come down to identifying which two principles are in tension and choosing the response that best protects the patient's right to decide.
The idea in one paragraph
Autonomy is the patient's right to make decisions about their own care, including refusal, even when the choice looks unwise to the team. Beneficence is the duty to act for the patient's benefit. Non-maleficence, 'do no harm', restrains that duty from tipping into harm. Justice means fair distribution of resources and care regardless of a patient's background. Fidelity is keeping the commitments a nurse makes to a patient, and veracity is telling the truth even when it is uncomfortable.
These six principles are not ranked. A situation is an ethical dilemma precisely because two of them point in different directions, and neither answer is free of cost.
Why it matters clinically
A nurse who defaults to beneficence alone will override patient wishes in the name of 'what's best', which is paternalism, not care. A nurse who defaults to autonomy alone will hand over painful truths and let patients decline needed care without checking understanding first. Clinical ethics is choosing, case by case, which principle carries more weight given the facts in front of you.
These principles also shape legal exposure. Failing to disclose a medication error violates veracity and can constitute negligence. Ignoring a competent patient's refusal violates autonomy and can constitute battery. The ethics and the law frequently point the same direction.
How to apply it at the bedside
Before acting, name which principle is under pressure. A patient refusing a blood transfusion on religious grounds is exercising autonomy; your role is to confirm capacity, ensure informed refusal, and document, not to persuade them out of a competent decision. A patient asking you not to tell their spouse about a new diagnosis raises fidelity and veracity questions that need a conversation about who else is entitled to that information.
When resources are scarce, justice governs: a single ICU bed goes by clinical criteria, not by who arrived first or who a nurse likes better. When a treatment's burden might outweigh its benefit, beneficence and non-maleficence have to be weighed against each other explicitly, usually with the care team and family present.
Where students get it wrong
Students often treat beneficence as the automatic correct answer because it sounds like 'good nursing.' It is not automatically correct when it conflicts with a competent patient's autonomy. The exam rewards recognising the conflict, not picking the principle that sounds kindest.
Another common error is confusing veracity with disclosure obligations that belong to the physician, such as diagnosis or prognosis. A nurse's duty of veracity covers what the nurse says and does, including answering questions honestly within their scope, not delivering news that belongs to another provider.
Worked examples
A terminally ill patient with capacity requests no further resuscitation attempts, against the family's wishes. Autonomy governs: document the patient's wishes, ensure an advance directive or POLST reflects them, and support the family separately rather than overriding the patient.
Two patients need the same donor organ and only one is available. Justice governs: allocation follows established clinical and organizational criteria, not staff preference, relationship to the patient, or order of request.
How the exam tests it
NCLEX items rarely name the principle outright. They describe a scenario and ask which principle is being upheld, violated, or is in conflict, or they ask for the best nursing response given a named principle. The strongest strategy is to identify the two principles in tension before reading the answer choices, then eliminate any option that resolves the tension by overriding a competent patient's stated wishes.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our fundamentals practice questions are the closest set to what this page covers.
Common questions
What is the difference between beneficence and non-maleficence?
Beneficence is the active duty to do good and benefit the patient. Non-maleficence is the duty to avoid causing harm. They usually align but can conflict, for example when a beneficial treatment carries significant risk of harm.
Can a nurse override patient autonomy for the patient's own good?
Not if the patient has decision-making capacity. A competent patient's refusal must be honored even when the team disagrees; overriding it without a legal basis such as incapacity or an emergency exception is both an ethics violation and a legal one.
What does veracity require when a patient asks a difficult question?
It requires an honest answer within the nurse's scope, delivered with appropriate sensitivity. It does not require volunteering information that belongs to another provider's disclosure, such as a diagnosis the physician has not yet discussed.
How does justice apply outside of organ or resource allocation?
Justice governs everyday decisions too, such as how attention and pain management are distributed across a patient assignment. It means care is not shaped by a patient's insurance status, background, or how demanding they are.
