Which vital sign is measured by the number of beats per minute in an animal?

• A. Blood pressure
• B. Respiratory rate
• C. Heart rate
• D. Temperature

Answer: (C)

The vital sign that is measured by the number of beats per minute in an animal is heart rate. Heart rate specifically refers to the frequency of the heartbeat, which can be detected by feeling the pulse or listening to the heart with a stethoscope. It provides crucial information about the animal’s cardiovascular health, indicating how well the heart is functioning to circulate blood throughout the body. In contrast, blood pressure measures the force of blood against the walls of the arteries and is expressed in mmHg rather than beats per minute. Respiratory rate calculates the number of breaths taken in a minute, which is a different aspect of the animal's health, focusing on the respiratory system. Temperature refers to the animal’s internal body temperature and is measured in degrees, not in terms of frequency as with heartbeat. Therefore, heart rate is the only vital sign among the options that directly corresponds to beats per minute.
