What power source powers a vital signs machine?

• A. Wind-up
• B. Solar
• C. Battery power
• D. Gas power

Answer: (C)

Vital signs monitoring needs a power source that keeps the device running when it’s moved or when a wall outlet isn’t available. Battery power is the best choice because it provides portability, allows continuous operation during transport or in rooms without immediate access to mains, and serves as a built-in backup if power is lost. Wind-up isn’t suitable for electronic medical monitors since they require steady electrical energy, not manual cranking. Solar power isn’t the standard primary source for bedside monitors (though some portable devices can be charged remotely by solar in special settings). Gas power isn’t used to power medical electronics. So, battery power is the appropriate answer.
