Which vital sign is a measure of the force of blood against the walls of arteries?

• A. Heart rate
• B. Respiratory rate
• C. Blood pressure
• D. Body temperature

Answer: (C)

Blood pressure is a vital sign that specifically measures the force exerted by circulating blood against the walls of the arteries. It is typically expressed as two numbers: systolic pressure, which represents the pressure when the heart beats and pumps blood, and diastolic pressure, which indicates the pressure when the heart is at rest between beats. This measurement is critical in assessing overall cardiovascular health and can indicate whether an individual may be experiencing conditions such as hypertension (high blood pressure) or hypotension (low blood pressure). In contrast, heart rate measures the number of times the heart beats per minute, respiratory rate evaluates how many breaths a person takes in a minute, and body temperature assesses the body's temperature regulation. While all these vital signs are important indicators of a person's health, only blood pressure directly reflects the force of blood against arterial walls.
