NRRPT CABT Healthcare Safety Standards & Regulations 5

Question 1

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:

Accepted Answer

20% of the prescribed dosage

Answer

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.

Question 2

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

Accepted Answer

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

Answer

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).

Question 3

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

Accepted Answer

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

Answer

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.

Question 4

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

Accepted Answer

The applicable dose limits and shielding design goals for those spaces

Answer

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.

Question 5

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

Accepted Answer

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

Answer

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.
