Radiography

Patient Care is worth 33 of the 200 scored items, all in the subcategory Patient Interactions and Management. It covers everything a radiographer does for the patient apart from making the exposure: legal and ethical duties, communication and patient education, safe transfers and monitoring, emergencies, infection control, hazardous materials, and contrast media. Expect scenario questions that ask for the first or most appropriate action, questions that name a legal term from a short description, and at least one contrast-dose or lab-value item.

Ethical Principles and the ARRT Standards of Ethics

The ARRT Standards of Ethics have two parts. The Code of Ethics is aspirational: it describes the professional conduct every radiographer should strive for, such as acting in the patient's interest, respecting dignity, and continuing to learn. The Rules of Ethics are mandatory and enforceable: they list specific conduct (for example, fraud on an application, practicing outside the scope of practice, sexual misconduct, or failing to report a conviction) that can lead to sanctions, up to revocation of ARRT credentials. Certified technologists must report certain events, such as criminal convictions, to ARRT.

Patients' Rights and Consent

The American Hospital Association's Patient Care Partnership summarizes what patients can expect: high-quality care, a clean and safe environment, involvement in their care, protection of their privacy, help preparing for discharge, and help with billing. Patients have the right to privacy, to information about their care, to refuse treatment, and to have their wishes followed through advance directives: a living will states which treatments the patient wants or refuses if unable to decide, a health care proxy (durable power of attorney for health care) names a decision-maker, and a do not resuscitate (DNR) order directs that CPR not be performed. Patients also have the right to decide whether to take part in research.

A patient may withdraw consent at any time, even after signing. If a patient refuses, stop, do not argue or coerce, and notify the physician or supervisor. Continuing after a refusal is battery.

Confidentiality is protected by the Health Insurance Portability and Accountability Act (HIPAA). Protected health information may be used for treatment, payment, and health care operations, and staff should access only the minimum necessary information. Never discuss patients in public areas, leave images or worklists visible to others, or share log-in credentials.

Verification prevents many legal problems: identify every patient with two identifiers (full name and date of birth or medical record number, never room number), compare the order with the clinical indication and the patient's history, and confirm the correct examination and side. Report a discrepancy to the ordering provider before imaging; document any change to the order. Accurate exam coding links the procedure performed to the order.

Restraints versus positioning aids. Sponges, sandbags, compression bands, and a Pigg-O-Stat used briefly to eliminate motion during an exposure are positioning or immobilization aids. Devices that restrict a patient's freedom of movement beyond the exposure are restraints and require a physician's order and facility policy; misuse can be false imprisonment.

Manipulation of electronic data. Digital images can be altered, and some alterations misrepresent the examination. Electronically cropping or masking an image to hide the fact that the beam was not collimated, changing the exposure indicator, or removing anatomy from the image is unethical and may be illegal. Collimation must be performed with the collimator at the time of exposure; electronic masking may only improve viewing and must never hide anatomy or the true exposed field.

Documentation. Record the examination performed, the number of images, any repeat and its reason, changes to the order, contrast given (agent, amount, route, lot number where required), patient condition, and any medical event, such as a fall or reaction. Incident reports are factual and objective, completed promptly, and are not placed in the patient's chart.

Communication and Patient Education

Communication is verbal or written (words, tone, instructions, consent forms) and nonverbal (eye contact, facial expression, posture, touch, and personal space). Nonverbal cues often carry more meaning than words, and touch used appropriately (a hand on the shoulder, guiding a limb into position after explaining why) reassures patients. Introduce yourself, identify the patient, explain the procedure in plain language, and check understanding by asking the patient to repeat the key instructions in their own words (teach-back). Avoid medical jargon, or explain terms when you must use them.

Patient Education

Explain the purpose of the examination, how long it will take, what the patient will feel or be asked to do, and, when asked, the radiation dose in understandable terms (for example, comparing it with natural background radiation) while noting the steps taken to keep it low. Scheduling considers procedure length, patient condition and age (diabetic patients and young children early in the day when fasting is required), and preparation. Give pre- and post-examination instructions clearly: diet and bowel preparation, medications to take or hold, the need for an interpreter, and discharge instructions (after barium, drink fluids and expect light-colored stools; report constipation).

Patients often ask about other modalities. Ultrasound uses sound waves and MRI uses a magnetic field and radio waves, so neither uses ionizing radiation; MRI requires screening for implants, pacemakers, and metal. CT and nuclear medicine use ionizing radiation; nuclear medicine uses radioactive tracers given to the patient. Preparations differ: CT and fluoroscopy may require contrast, and nuclear medicine may require fasting or stopping certain medications.
