Exam category: Patient Care → Ethical and Legal Aspects
Why it matters: This is one of the highest-yield "easy point" topics on the registry. The concepts are logic-based, not math-based — if you understand the reasoning, you rarely need to memorize.
Everything here boils down to one idea: the patient is a person with rights, and you are legally accountable for how you treat them. Every rule below exists to protect either the patient's right to control what happens to their body and information, or to define what happens legally when something goes wrong.
Informed consent means a patient has been told what will happen, why, what the risks and alternatives are, and has agreed to it before it happens. Three types:
| Type | What it looks like |
|---|---|
| Written | Signed document (e.g. a contrast-enhanced exam consent form) |
| Oral (verbal) | Spoken agreement, often witnessed/documented |
| Implied | Patient's actions show agreement (e.g. positioning themselves for the exam without objection) |
Consent for the medical procedure itself is generally obtained by the physician or ordering provider, not the radiographer. The radiographer's job is to explain the radiographic procedure itself — what will happen in the room, positioning, breathing instructions — and verify the patient understands. A patient can refuse any part of an exam at any time, even after starting it; refusal must be documented and reported to the ordering provider.
The Privacy Rule protects PHI (Protected Health Information) — any individually identifiable health information, in any form. PHI can be shared without patient authorization for three purposes only:
Memory cue — TPO: Treatment, Payment, Operations. Outside those three, disclosure needs the patient's written authorization.
The "minimum necessary" standard applies outside treatment-related sharing: only share the minimum PHI needed for the purpose. Discussing a patient's condition in a public hallway, or a coworker uninvolved in that patient's care asking out of curiosity, are both HIPAA violations regardless of intent.
Covers privacy, DNR (Do Not Resuscitate), access to information, and advance directives. Two documents worth telling apart:
Both only take effect once the patient can't make decisions themselves — an awake, competent patient still makes their own calls, even if they conflict with either document.
Research participation is on that same list of rights, and it runs through consent. Routine care is covered by the consent given on admission, but a procedure carrying substantial risk — or one that is experimental — needs its own informed consent first. So a patient always decides for themselves whether to take part in a study or an investigational procedure, and declining costs them nothing in the standard care they'd otherwise receive.
| Term | Meaning |
|---|---|
| Negligence | Failing to act as a reasonably careful technologist would, causing harm |
| Malpractice | Negligence committed by a licensed/credentialed professional |
| Battery | Touching/performing a procedure without consent |
| Assault | Making a patient reasonably fear unconsented touching — no touching required |
| Respondeat superior | Employer can be held liable for an employee's actions within the scope of their job |
| Res ipsa loquitur | Some injuries are so obviously the result of negligence that it doesn't need separate proof |
Before you image anyone, two separate checks have to pass, and they protect against two different errors.
Skipping the two-identifier check is a textbook negligence scenario — it's the failure to do what a reasonably careful technologist would do, and the harm (wrong exam, wrong patient, unnecessary dose) follows directly.
Restraints vs. immobilization: immobilization devices (sponges, sandbags, straps) support voluntary cooperation. Restraints limit movement against the patient's will and generally require a physician's order — a last resort, not a convenience tool.
Altering an exposure indicator, processing settings, or cropping/masking anatomy specifically to hide a technical error — rather than reporting and repeating appropriately — is both an ethics and (potentially) a fraud violation. The image should be an honest representation of what happened.
Ethics isn't just the legal-terminology list above — it rests on a set of named moral principles that show up throughout patient-care reasoning, including inside the ARRT Code of Ethics itself. Beneficence is the one named directly in the registry's own outline:
| Principle | Meaning |
|---|---|
| Beneficence | Goodness — acting in a way that brings about good for the patient |
| Nonmaleficence | "First, do no harm" — an obligation not to inflict harm |
| Autonomy | Self-determination — respecting a patient's independence and their right to decide for themselves |
| Justice | Fairness — an obligation to act with equity |
| Veracity | Truthfulness — an obligation to tell the truth |
| Fidelity | Faithfulness — an obligation to be loyal to the patient and the profession |
These aren't abstract — they're the reasoning behind rules you already know. Autonomy is why a competent patient can refuse an exam (§1). Veracity and nonmaleficence are why disguising a technical error (§5) is an ethics violation, not just sloppy work. Beneficence is the standard the ARRT's own Code of Ethics points to when it says a technologist acts in the best interest of the patient.
Memory cue — it's six, not four: general bioethics courses often teach just four principles (autonomy, beneficence, nonmaleficence, justice). Your radiography source recognizes six — don't drop veracity and fidelity if a registry question lists all six as answer choices.
| Part | Nature |
|---|---|
| Code of Ethics | Aspirational — describes ideal conduct, not independently enforceable |
| Rules of Ethics | Mandatory and enforceable — violations can mean sanctions, including loss of certification |
Registered Technologists must report a known or suspected ethics violation — including their own — within 30 days of the occurrence or at renewal, whichever comes first.
Registry questions like to disguise a battery scenario as a simple "difficult patient" story — if a competent patient has clearly said no and the technologist proceeds anyway, that's battery, not just poor bedside manner. Similarly, questions try to get you to say the technologist obtains informed consent for an invasive procedure like an arthrogram — it's the performing/ordering physician, even if the technologist witnesses a signature. A third trap: assuming the ethical-principles list stops at the general "autonomy, beneficence, nonmaleficence, justice" four — your source's list has six, and a question can test veracity or fidelity by name.
