What item is used to measure pulse rate for a full minute?

• A. Stethoscope
• B. Doppler
• C. Thermometer
• D. Watch/Clock with second hand

Answer: (D)

Counting pulse rate accurately for a full minute relies on a timing device that shows seconds. A watch or clock with a second hand lets you start counting the beats and stop exactly after 60 seconds, giving the beats per minute. This approach reduces error, especially if the pulse rhythm is irregular. You can palpate the pulse at the wrist or neck while watching the second hand to record the rate. The stethoscope or Doppler can help you hear the pulse when it’s hard to feel, but they don’t provide a timing function on their own. A thermometer measures temperature, not pulse rate.
