A woman in her 26th week of pregnancy states that she is "not really short of breath" but feels that she is aware of her breathing and the need to breathe. What is the best reply by the nurse?

A) "The diaphragm becomes fixed during pregnancy, making it difficult to take in a deep breath."
B) "The increase in estrogen levels during pregnancy often causes a decrease in the diameter of the rib cage and makes it difficult to breathe."
C) "What you are experiencing is normal. Some women may interpret this as shortness of breath, but it is a normal finding and nothing is wrong."
D) "This increased awareness of the need to breathe is normal as the fetus grows because of the increased oxygen demand on the mother's body, which results in an increased respiratory rate."

Final Answer : C, Explanation :  During pregnancy, the woman may develop an increased awareness of the need to breathe. Some women may interpret this as dyspnea, although structurally nothing is wrong. Increases in estrogen relax the chest cage ligaments, causing an increase in the transverse diameter. Although the growing fetus increases the oxygen demand on the mother's body, this increased demand is easily met by the increasing tidal volume (deeper breathing). Little change occurs in the respiratory rate.
