The fluoroscopy timer must provide signal after how much fluoroscopic time has elapsed?

• A. 30 seconds
• B. 1 minute
• C. 2 minutes
• D. 5 minutes

Answer: (D)

The main idea is to keep fluoroscopy exposure under control by giving the operator a clear alert to reassess technique and dose immediately before exposure could become excessive. An audible signal after a defined fluoroscopic time helps ensure a prompt pause to review settings, use dose-saving practices, and check protective measures. Five minutes is the commonly adopted trigger because it provides a practical balance: it allows enough time for necessary imaging during a complex procedure, but it prompts a break or technique review before exposure risks accumulate significantly for patient and staff. When the timer sounds, you should evaluate factors such as the frame rate, the use of pulse fluoroscopy, last-image hold, and shielding, and implement steps to reduce exposure. Shorter intervals like thirty seconds or one or two minutes would disrupt normal workflow with frequent alarms, while five minutes aligns with standard safety practice and dose management.
