To maintain the accuracy of medical equipment, what action must a medical assistant avoid?

• A. Calibrating equipment daily
• B. Cleaning equipment with water
• C. Using faulty equipment
• D. Replacing batteries

Answer: (C)

Maintaining the accuracy of medical equipment depends on using devices that are functioning properly and properly maintained. The action to avoid is using equipment that is faulty or malfunctioning. When faulty equipment is used, readings can be inaccurate, leading to incorrect diagnoses, inappropriate treatments, or patient harm. Before each use, devices should be checked for proper operation, and any faulty equipment should be removed from service and repaired or replaced. Regular calibration and correct battery power are part of keeping equipment accurate, while cleaning should follow the manufacturer’s instructions—water exposure or improper cleaning can damage sensitive devices and alter readings.
