Sphygmomanometer measures Only one correct answerA.Blood glucose levelB.Rate of transpirationC.Air pressureD.Blood pressure

Understanding the Question

The problem asks to identify what a sphygmomanometer measures from the given options.

Relevant Concepts

A sphygmomanometer is a medical instrument specifically designed to measure blood pressure. It works by temporarily stopping the flow of blood in an artery and then measuring the pressure in that artery as the blood starts to flow again.

Analyzing the Options

1. A. Blood glucose level: This is measured by a glucometer, not a sphygmomanometer.
2. B. Rate of transpiration: This pertains to plant physiology and is measured using different methods, not by a sphygmomanometer.
3. C. Air pressure: This is measured using a barometer, not a sphygmomanometer.
4. D. Blood pressure: As already established, this is the correct function of a sphygmomanometer.

Verify and Summarize

Each option was analyzed based on the scientific principles of measurement. The only correct measurement associated with a sphygmomanometer is blood pressure.

Final Answer

D. Blood pressure
