In a blood pressure reading, the bottom number represents the __________ of sounds or cessation of sounds.

• A. Change in sounds
• B. First diastolic sound
• C. Cessation of sounds
• D. Systolic measurement

Answer: (C)

The bottom number in a blood pressure reading corresponds to the point of cessation of sounds. This measurement is known as the diastolic pressure, which indicates the pressure in the arteries when the heart is at rest between beats. During the process of measuring blood pressure using a sphygmomanometer and a stethoscope, the healthcare provider listens for the Korotkoff sounds. The first sound heard indicates the systolic pressure, while the last sound heard—or the point at which the sounds stop completely—marks the diastolic pressure. Therefore, understanding that the bottom number reflects the cessation of sounds is crucial for accurately interpreting blood pressure readings. This concept is fundamental in clinical practice, as it helps assess the overall cardiovascular health of an individual. Properly identifying the cessation of sounds ensures accurate blood pressure monitoring, leading to better patient care.
