CABT Healthcare Safety Standards & Regulations Flashcards

A nuclear medicine technologist administers a diagnostic radiopharmaceutical to the wrong patient. Under 10 CFR 35.3045, this is reportable if the administered dosage differs from the prescribed dosage by more than:

Answer: 20% of the prescribed dosage

A medical event in diagnostic nuclear medicine is triggered when the administered dosage differs from the prescribed dosage by more than 20% per 10 CFR 35.3045 criteria.

What type of shielding requirement typically applies to rooms where x-ray fluoroscopy is permanently installed in a US hospital?

Answer: Shielding designed to maintain doses below 1 mSv/week for controlled areas and 0.02 mSv/week for uncontrolled areas

NCRP Report No. 147 and state/NRC regulations require shielding designs that maintain weekly doses below 1 mSv for controlled areas (radiation workers) and 0.02 mSv for uncontrolled areas (public).

What is the NRC's requirement for 'declared pregnant workers' in terms of fetal dose monitoring?

Answer: A separate deep-dose badge worn at the abdomen is required to estimate fetal dose

Facilities typically issue a second dosimeter to be worn at the abdomen to estimate fetal dose throughout the declared pregnancy in compliance with 10 CFR 20.1208.

The concept of 'controlled area' vs. 'uncontrolled area' in a hospital radiation facility primarily affects which regulatory requirement?

Answer: The applicable dose limits and shielding design goals for those spaces

Controlled areas are occupied by radiation workers with dose limits of 50 mSv/year; uncontrolled areas are occupied by the public with a limit of 1 mSv/year, directly driving shielding design.

Under Joint Commission standards, when a healthcare facility identifies a radiation safety near-miss event, what is the expected organizational response?

Answer: Conduct a proactive risk assessment and implement corrective actions to prevent recurrence

The Joint Commission expects healthcare organizations to analyze near-miss events using proactive risk assessment methods (such as FMEA) and implement corrective actions to prevent future occurrences.

Which 10 CFR Part 20 section governs the concentration limits for releasing radioactive effluents into sanitary sewerage systems from hospital nuclear medicine departments?

Answer: 10 CFR 20.2003

10 CFR 20.2003 establishes the conditions and concentration limits under which licensed radioactive material may be released into sanitary sewerage systems.

A healthcare facility wants to release a patient treated with iodine-131 for thyroid cancer. Which regulatory guidance most directly governs when the patient may be released based on radiation exposure to members of the public?

Answer: 10 CFR 35.75 — release of individuals containing unsealed byproduct material

10 CFR 35.75 specifically authorizes release of patients administered radiopharmaceuticals when the total effective dose equivalent to any other individual is unlikely to exceed 5 mSv.
