Ethics, law and communication
- Patient Identification and VerificationBefore any exposure, match two identifiers from the patient to the wristband and the order.
- Informed Consent and CommunicationValid consent means a competent patient understands the exam, its risks and options, and agrees freely.
- Patient Privacy, Ethics, and Cultural CompetenceShare only what care requires, protect dignity, and adapt to each patient's culture without assumptions.
- Legal Issues, Doctrines and DocumentationTouch without consent is battery, an unneeded restraint is false imprisonment, and the employer answers for your work.
Assistance, monitoring and emergencies
- Patient Transfer and Body MechanicsWide base, bent knees, load close, no twisting, and wheels locked before every transfer.
- Vital Signs and MonitoringKnow adult normal ranges, take your own baseline, and report any significant change right away.
- Pediatric immobilizationDevices before people, the shortest exposure time, and no holder ever in the primary beam.
- Pediatric and Geriatric ConsiderationsChildren need the lowest dose and honest, simple talk; older adults need time, support, and gentle handling.
- Tubes, Lines, and OxygenIV bags above the site, drains and urine bags below. Never clamp a chest tube, and keep oxygen at the ordered rate.
- Trauma and Emergency ResponseMove the tube and receptor, not the patient, and keep immobilization on until a physician clears the spine.
- Medical EmergenciesRecognize the signs, call for help early, and stay with the patient. Anaphylaxis needs epinephrine and a code call.
Infection control
- Infection Control and Standard PrecautionsTreat every patient as potentially infectious, and add contact, droplet, or airborne precautions when needed.
- Sterile Technique and Hazardous MaterialsOnly sterile touches sterile, anything below the table edge is contaminated, and the SDS tells you how to handle a chemical.
Pharmacology and contrast
- Medications and RoutesKnow the route, check the six rights, and recognize the crash cart drugs. Give drugs only on order and within policy.
- Venipuncture and IV SafetyHigher gauge means a smaller needle. Watch the site during every injection and drop used sharps in the container at once.
- Contrast Agents and Patient PrepNonionic iodine has lower osmolality and fewer reactions. Suspected perforation means water-soluble contrast, not barium.
- Contrast Media Reactions and ManagementStay with the patient after injection, spot the early signs, and know your first steps if a reaction starts.
