What is the correct method for measuring blood pressure?

• A. With a thermometer and a wrist cuff
• B. Using a sphygmomanometer and stethoscope
• C. By feeling the pulse on the wrist
• D. Utilizing a digital watch

Answer: (B)

The correct method for measuring blood pressure involves using a sphygmomanometer and a stethoscope. The sphygmomanometer consists of an inflatable cuff that is applied to the upper arm to temporarily stop blood flow in the artery. As the cuff is inflated and then slowly deflated, the healthcare provider listens with a stethoscope for the sounds of blood flow, known as Korotkoff sounds, which indicate the systolic and diastolic pressures. This method is the standard practice in clinical settings because it provides accurate and reliable measurements. The stethoscope allows for precise auditory detection of the blood flow sounds, which is essential for correctly identifying the exact points at which the blood starts and stops flowing when the cuff pressure is released. Other methods, such as using a thermometer, feeling the pulse on the wrist, or utilizing a digital watch, do not provide accurate blood pressure readings. A thermometer measures body temperature, while palpating the pulse can give an indication of heart rate but does not provide blood pressure information. Digital watches, unless specifically designed as blood pressure monitors, cannot measure blood pressure at all.
