The capacity to understand and share the feelings and perspectives of another person, fostering strong professional relationships, as contrasted with sympathy, which involves pity or sorrow.

Stages of Grief

The five emotional stages formulated in the Kübler-Ross model experienced by patients confronting serious diagnoses: denial, anger, bargaining, depression, and acceptance.

Pulse Oximetry

A noninvasive diagnostic monitoring method used to measure arterial oxygen saturation (normal range $95\text{--}100\%$) and assess pulse rate.

Normal Adult Body Temperature

A baseline physiological measurement averaging $98.6^{\circ}\text{F}\,(37^{\circ}\text{C})$, with variations signaling potential infection, inflammation, or systemic dysfunction.

Blood Pressure

A vital sign expressed as systolic pressure over diastolic pressure, with a normal resting adult baseline reading around $120/80\,\text{mm\,Hg}$.

Orthostatic Hypotension

A sudden reduction in blood pressure that occurs when a patient transitions to an upright standing posture, often producing vertigo, dizziness, or syncope.

Hypoxia

A state of insufficient tissue oxygenation that elicits physiological compensatory mechanisms, including elevated heart rate, increased respiratory rate, and heightened blood pressure.

Automated External Defibrillator (AED)

A portable emergency device that interprets underlying cardiac rhythms and administers an electric shock when indicated to restore a normal sinus rhythm.

Autonomy

The core bioethical principle recognizing the right of competent patients to make independent choices regarding their own healthcare and medical interventions.

Nonmaleficence

The ethical duty obligating radiographers to refrain from inflicting harm, operationalized by applying radiation shielding, safe equipment operation, and proper exposure factors.

Beneficence

The ethical obligation to actively advance patient well-being, demonstrated through reassurance, explaining examinations, and reducing patient physical discomfort.

Justice

The ethical mandate requiring fairness, equity, and impartiality in medical care regardless of a patient's age, race, gender, or socioeconomic status.

Veracity

The fundamental ethical principle requiring absolute honesty, truthfulness, and transparency in all professional communications with patients and colleagues.

Fidelity

The professional ethical duty of faithfulness and reliability, manifested by upholding confidentiality and honoring commitments made to patients.

Implied Consent

Non-verbal agreement inferred when a patient cooperatively positions themselves for an imaging examination following an explanation of the procedure.

False Imprisonment

The unlawful restriction, restraint, or immobilization of a patient without legal authority, adequate clinical justification, or informed consent.

Defamation

The dissemination of false statements—either spoken (slander) or written (libel)—that inflict injury upon an individual’s reputation or character.

Negligence

A breach of standard of care defined as the failure to exercise the degree of skill and prudence that a reasonably prudent technologist would demonstrate under comparable conditions.

Res Ipsa Loquitur

A Latin legal doctrine meaning 'the thing speaks for itself,' applied when an injury occurs under the exclusive control of medical personnel that would not normally happen without negligence.

Respondeat Superior

A legal doctrine holding healthcare employers vicariously liable for the negligent acts or omissions committed by employees working within the legitimate scope of their job duties.

Good Samaritan Law

Statutory legal protection provided to healthcare professionals who render emergency assistance outside hospital settings, provided actions are reasonable and within professional competence.

A document (formerly known as the Patient Bill of Rights) detailing legal and ethical patient rights, including access to medical records, respectful care, informed consent, and privacy.

Quality Assurance (QA)

A department-wide program that systematically audits imaging outcomes, equipment functionality, and repeat image rates to uphold operational imaging standards.

Continuous Quality Improvement (CQI)

A structured management approach focused on continuous, system-wide process enhancements rather than personal fault-finding, engaging all personnel to elevate care standards.
