Which of the following devices is designed for infection prevention using a disposable cover?

• A. Sphygmomanometer
• B. Digital Thermometer
• C. Stethoscope
• D. Surgical Mask

Answer: (B)

The digital thermometer is designed for infection prevention by utilizing a disposable cover or probe sheath. This feature allows for the thermometer to be used on multiple patients while minimizing the risk of cross-contamination and infection. The disposable cover acts as a barrier between the probing mechanism and the patient, ensuring that pathogens are not transmitted from one individual to another.

In contrast, other devices listed, like sphygmomanometers, often rely on disinfection protocols rather than disposable covers for maintaining cleanliness. Stethoscopes can be cleaned but typically do not use disposable components, and surgical masks are meant for protecting the wearer and preventing the spread of respiratory droplets rather than specifically for the purpose of measuring temperature in a way that facilitates infection control. Thus, the digital thermometer stands out as it directly incorporates a disposable element crucial for infection prevention in medical settings.
