A Febrile Patient's Mother Asks the Nurse Why Her Daughter's

A febrile patient's mother asks the nurse why her daughter's breathing rate is increased. The nurse replies:

A) "It is normal for the fever to increase her metabolic rate. Because the heart and lungs work together, you see her breathing speed up along with her heart rate."
B) "It is quite normal for this to happen, so you can expect her respiratory rate to increase by 8 to 10 respirations per minute for each 1°F elevation in temperature."
C) "Breathing speeds up when the temperature is elevated to blow off some of the body heat."
D) "It is rare that respirations are affected by fever. We should be very concerned about this."
