Anatomy & Physiology Respiratory #17

Question

Which respiratory rate is classified as tachypnea?

Answers

  1. 14 breaths per minute
    • Rationale:

      The normal range of respirations is 16 to 20 breaths per minute; therefore, a respiratory rate of 14 breaths per minute is classified as bradypnea, not tachypnea.

  2. 17 breaths per minute
    • Rationale:

      The normal range of respirations is 16 to 20 breaths per minute; therefore, a respiratory rate of 17 breaths per minute falls within the normal range of respiration and is classified as eupnea, not tachypnea.

  3. 20 breaths per minute
    • Rationale:

      The normal range of respiration is 16 to 20 breaths per minute; therefore, a respiratory rate of 20 breaths per minute falls within the normal range of respiration and is classified as eupnea, not tachypnea.

  4. 23 breaths per minute
    • Rationale:

      Tachypnea is defined as a respiratory rate that is more than the established normal range of 16 to 20 breaths per minute; therefore, a respiratory rate of 23 breaths per minute is classified as tachypnea.

Overview

Tachypnea is defined as an abnormally high respiratory rate.

Explanation

Learning Outcomes

The normal range for respirations is 16 to 20 breaths per minute. A respiratory rate that is less than 16 breaths per minute is referred to as bradypnea. A respiratory rate that is greater than 20 breaths per minute is referred to as tachypnea; therefore, 23 breaths per minute is classified as tachypnea.
