Which practice supports safe use of medical devices?

• A. Correct usage per manufacturer instructions
• B. Routine maintenance
• C. Reporting malfunctions
• D. All of the above

Answer: (D)

Safe use of medical devices relies on three integrated practices that together protect patients and staff. Using the device exactly as the manufacturer instructs ensures it is operated within its designed parameters, with the correct settings, indications, and workflow. Routine maintenance keeps the device functioning reliably—calibrations, cleaning, replacing worn parts, and checking batteries or power sources prevent drift or unexpected failures. Reporting malfunctions creates a safety feedback loop, so problems are investigated, fixes are applied, and alerts or recalls can be issued if broader risk is identified. When these elements are combined, you reduce the chance of user error, equipment failure, and unaddressed defects, providing the strongest protection for safe care. Focusing on only one aspect leaves gaps—following instructions without maintenance can miss wear-and-teardown issues; maintenance without reporting can miss latent faults; reporting without proper use and upkeep can allow unsafe operation to continue. All of the above.
