A Caregiver for a Child Who Is Undergoing Chemotherapy for Cancer

A caregiver for a child who is undergoing chemotherapy for cancer shares with the nurse that the child's temperature is being taken rectally every 4 hours. Which of the following is the nurse's best response?

A) "Good for you for paying close attention to whether your child has a fever or not."
B) "Once a day, at the same time each day, is the best practice for taking the temperature."
C) "It is not necessary to take the temperature so often. You need only take the child's temperature if you suspect fever."
D) "Stop this practice, because the thermometer can cause breaks in the rectal mucosa and cause bacteria to enter the bloodstream, resulting in sepsis or abscess."
