A nurse is obtaining vital signs from 2-month-old infant. The infant's heart rate is 190/min and his temperature is 40° C (104° F). The father asks the nurse why the infant's heart is beating so fast. Which of the following responses by the nurse is appropriate
"The fever is causing an increase in your baby's heart rate."
"Your baby's heart is beating fast in an attempt to cool down his body
“This is within the expected range for your baby."
"As your baby begins to fall asleep, his heart rate will decrease.
The Correct Answer is A
A. In the case of a fever, the body's response often includes an increase in heart rate to help distribute heat and manage the fever.
B. While the body might attempt to regulate temperature through various means, the increased heart rate is primarily due to the fever itself.
C. A heart rate of 190/min is higher than normal for a 2-month-old infant and is likely elevated due to the fever.
D. Heart rate tends to decrease during sleep but doesn't explain the elevated heart rate specifically in response to the fever.
