Respiratory rate is best described as the number of breaths per minute. Which option states this correctly?

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

Answer: (B)

This item tests your understanding of vital signs and what each one measures. Respiratory rate is the number of breaths a person takes each minute. The description that matches this exactly is respiratory rate, since it specifies breaths per minute. Other options refer to different vital signs: pulse means heartbeats per minute, temperature measures body heat, and blood pressure is the force of blood against artery walls. Knowing these distinctions helps you identify the correct description quickly. In healthy adults, a typical respiratory rate is about 12 to 20 breaths per minute, and clinicians often count for a full minute to be accurate.
