Nuclear Medicine-Exam 3 Answered
(verified 2025)
Define ejection fraction: - ANSWER-a measurement of the percentage of blood leaving
your heart each time it contracts
Define hydrocephalus. - ANSWER-hydrocephalus-excess fluid built up in brain
Define in-vitro and in-vivo with respect to pertechnetate red blood cell labeling. -
ANSWER--in-vitro- "within the glass" performed in a controlled environment outside of
the living organism
-in-vivo- "within the living" performed using a whole living organism
Define myocardial infarction: - ANSWER-perfusion defect on both rest and stress
Define myocardial ischemia: - ANSWER-perfusion defect on stress only
Define QRS complex: - ANSWER-a name for the combination of three of the graphical
deflections seen on a typical electrocardiogram (ECG). It is usually the central and most
visually obvious part of the tracing. It corresponds to the depolarization of the right and
left ventricles of the human heart.
Define quality assurance and identify items a nuclear medicine department may track as
part of its QA program. - ANSWER-on-going process that looks to see if objectives are
being met:
-patient satisfaction
-referring physician satisfaction
-systematic protocol review/update
-quality control on equipment
Define systole: - ANSWER-blood pressure number, number on top
Describe patient's rights in the context of an imaging study. - ANSWER--patient refuses
exam
-stopping an exam at patient request/demand
-patient wanting to know results (MUST fill out form)

study requisition- worksheet that is used at site but is not a legal means to perform a
scan (does not have to have a physician's signature)
Discuss factors that must be considered when multiple nuclear medicine studies are
ordered on a patient. - ANSWER--time between
-medication
-type of radiopharmaceuticals used
Discuss patient preps that must be considered when scheduling nuclear medicine
studies: bone scan, hepatobiliary study, thyroid scan and uptake, stress cardiac studies,
gastric emptying and renal studies. - ANSWER--medication discontinuance
-NPO
-hydration
-reason for study
-need for delayed views
-physician involvement (Does physician have to be there?)
-acquisition type
-other possible procedures on same day
-multiple nuclear medicine procedures
Explain and demonstrate acceptable practices for identifying the patient. - ANSWER-
two responsive identifiers:
-full name
-birthdate
Explain the acceptable practices for confirming the correct radiopharmaceutical and
dosage. - ANSWER--check dosage on radiopharmaceutical prescription
-assay dose in calibrator and check that amount matches prescription
-confirm patient name on radiopharmaceutical
-recheck everything
-finally check syringe tab before injection
Explain the function of The Joint Commission and its role within the hospital
environment. - ANSWER--accredits hospitals to make sure they are upholding the rules
(voluntary but necessary)
-do on-site inspections for the entire healthcare facility
Explain the only reason one should access a patient's Protected Health Information
(PHI). - ANSWER-ONLY if it is needed in order to do your job properly
