15.1 Patient Care, Education, and Consent
Key Takeaways
- HIPAA requires minimum necessary use/disclosure of PHI; nuclear medicine technologists protect identity, images, reports, and spoken details in public areas, elevators, and waiting rooms.
- Verify identity with at least two identifiers (armband + verbal name/DOB ± barcode scan) before every radiopharmaceutical administration, and reconcile the written/electronic order with the scheduled study and dose.
- Pre-exam screening covers prep compliance, pregnancy/breastfeeding, contraindications, history, medications, allergies, recent contrast/procedures, and labs (e.g., creatinine before CT contrast; TSH/pregnancy when protocol requires).
- Informed consent may be written or verbal per procedure risk and institutional policy; technologists educate on what happens, radiation precautions, activity restrictions, and therapy/inpatient release criteria—not medical diagnosis.
- Emergency readiness includes recognizing syncope, seizure, and code responses; post-procedure assessment and correct biohazard disposal (sharps, blood, contaminated waste) close the care loop.
15.1 Patient Care, Education, and Consent
Quick Answer: Protect PHI (HIPAA), confirm two patient identifiers, screen prep/contraindications/history/meds/allergies/labs, obtain or confirm informed consent, educate on procedure + precautions + release, and be ready for syncope, seizure, or code. Transfer safely, manage support devices (e.g., Foley), assess after the study, and dispose of biohazard/sharps correctly.
Clinical Procedures (Domain V) treats every study as a patient-care episode. CNMT items test the full sequence—from greeting through release—not only collimator choice.
HIPAA Privacy in the Nuclear Medicine Suite
The Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule governs protected health information (PHI): names, medical record numbers, dates of birth, images, reports, appointment lists, and verbal details that can identify a patient.
| Practice | Why it matters |
|---|---|
| Discuss cases only with need-to-know staff | Minimum necessary standard |
| Avoid hallway/elevator/waiting-room clinical talk | Incidental disclosure risk |
| Log off workstations; face monitors away from public view | Screen privacy |
| Release images/results only through authorized channels | Patient rights + institutional policy |
| Shred or secure printed schedules with PHI | Paper is still PHI |
Nuclear medicine adds unique PHI vectors: hot-lab dose logs, camera worklists, and therapy written directives. Do not photograph identifiers on personal devices; de-identify teaching cases per policy.
Basic Patient Care: Vitals, First Aid, Infection Control
Technologists obtain or document vital signs when ordered or protocol-required (e.g., pharmacologic stress, therapy observation, unstable patients). Flag emergencies such as sudden hypotension after upright transfer, chest-pain tachycardia, or desaturation.
First aid / emergency recognition at the tech level:
| Situation | Immediate tech actions (high-level) |
|---|---|
| Fainting (syncope) | Support patient to floor safely, protect head, elevate legs if appropriate, call for help, check responsiveness/breathing |
| Seizure | Protect from injury, time the event, do not force objects into the mouth, recovery position when safe, activate emergency response |
| Code / unresponsiveness | Call code team, begin BLS per training/certification, retrieve crash cart/AED, clear space for responders |
Infection control: hand hygiene; standard precautions for all patients; transmission-based precautions as posted; disinfect camera surfaces, pads, and positioning aids between patients. Blood-borne pathogen spills follow institutional BBP procedures—not identical to a radioactive spill workflow (both may apply after a therapy accident).
Transfer Techniques and Support Devices
Safe transfer prevents falls and line disconnections. Assess mobility, use gait belts/slide boards when indicated, lock brakes, and never leave a fall-risk patient unattended on the table. For Foley catheters, keep the bag below bladder level, avoid kinks, and never rest it on the abdomen or detector. Keep IVs, oxygen, chest tubes, and drains patent during table motion—coordinate with nursing before disconnecting.
Patient Identification, Orders, and Pre-Exam Screening
Identification uses at least two identifiers—commonly armband name/MRN plus verbal full name and date of birth, often with barcode scan. Verify identity immediately before radiopharmaceutical administration, not only at check-in hours earlier.
Orders: confirm the electronic/written order matches the scheduled procedure, laterality/site when relevant, and authorized prescribing clinician. Question incomplete, conflicting, or outdated orders before drawing or administering activity.
Pre-exam screening checklist (exam favorites):
| Screen item | Examples / why |
|---|---|
| Prep compliance | NPO, low-iodine diet, bowel prep, hydration, voiding |
| Contraindications | Pregnancy for many studies; specific agent allergies; inability to lie flat for long SPECT when no alternative |
| History | Prior NM studies, surgery, known disease, claustrophobia |
| Medications | Interfering drugs (e.g., for MIBG, thyroid, cardiac stress protocols) |
| Allergies | Contrast, latex, medications used as adjuncts |
| Labs / special status | Creatinine/eGFR before IV CT contrast; pregnancy test; TSH status for thyroid cancer pathways |
| Recent procedures | Iodinated contrast, barium, other tracers still on board |
Document positive findings and escalate to the authorized user/physician when the study should be delayed, modified, or cancelled.
Informed Consent: Written vs Verbal
Informed consent means the patient (or legal surrogate) understands the procedure, material risks/benefits/alternatives at an appropriate level, and agrees voluntarily. Low-risk diagnostic exams often use verbal consent plus education; invasive procedures, research, and many therapeutic administrations require written consent (therapy also ties to written directives).
Technologists confirm consent, answer logistics questions, and stop if consent is revoked or capacity is unclear—never pressure patients. Use plain language.
Education, Precautions, Restrictions, and Release Criteria
Teach what will happen (injection, wait, scan length, breath-holds), radiation precautions when applicable (hydration/voiding for bladder dose reduction; time/distance/hygiene after therapy), activity restrictions (driving after sedation, close contact with infants after high-activity therapy), and when to seek care (infiltrate symptoms, allergic reaction).
| Setting | Education focus |
|---|---|
| Outpatient diagnostic | Timing, NPO if needed, post-void imaging, usual daily activity unless instructed |
| Inpatient | Coordinate transport, lines, isolation status, nursing handoff of residual activity/precautions |
| Travel | Airport/monitor letters for residual activity when policy provides them |
| Therapy (e.g., I-131) | Home isolation rules, toilet hygiene, laundry, duration of restrictions, release criteria based on dose rate/activity rules |
Release criteria after therapy follow NRC/agreement-state rules—technologists measure dose rates and document teaching, but the authorized user owns medical release decisions.
Post-Procedure Assessment and Biohazard Disposal
After imaging or therapy, reassess comfort, access sites, vitals when indicated, and ambulation. Report complications promptly. Dispose of sharps in puncture-resistant containers; bag blood-contaminated materials as biohazard; segregate radioactive waste per half-life and license rules—never mix ordinary trash with radioactive or infectious waste.
Bottom line: privacy + two identifiers + order/screen/consent + education + emergency readiness + clean disposal define safe CNMT-level patient care.
