Which measurement helps in determining the efficiency of the heart's function?

• A. Body temperature
• B. Respiration rate
• C. Pulse rate
• D. Body weight

Answer: (C)

The measurement that helps in determining the efficiency of the heart's function is the pulse rate. The pulse rate, which reflects the number of times the heart beats per minute, provides essential information about how well the heart is performing its role in circulating blood throughout the body.

A normal pulse rate indicates that the heart is functioning efficiently to supply oxygenated blood to tissues and organs. An elevated or abnormal pulse rate may suggest that the heart is under stress or working harder than normal, which could be due to various factors such as physical activity, emotional stress, or underlying health conditions.

In contrast, body temperature, respiration rate, and body weight are important vital signs but do not provide direct information about the heart's function. Body temperature can indicate infection or inflammation, respiration rate reflects lung function, and body weight can provide clues about overall health and nutrition, but they do not specifically measure how effectively the heart is working.
