How does the respiratory rate of a pregnant woman typically change during pregnancy?

• A. It decreases
• B. It increases
• C. It remains unchanged
• D. It varies significantly

Answer: (C)

During pregnancy, the respiratory rate of a woman typically remains unchanged, which makes this answer accurate. Although there are a number of physiological changes that occur during pregnancy, such as increased tidal volume and changes in lung mechanics, the overall rate of breathing tends to stay stable. As the pregnancy progresses, the body adapts by increasing the efficiency of gas exchange rather than drastically altering the respiratory rate. Pregnant women may experience shortness of breath due to the diaphragm being displaced by the growing uterus, but this does not mean an actual increase in the baseline respiratory frequency. Therefore, the option that indicates no significant change in respiratory rate accurately reflects the typical physiological response during pregnancy.
