Is it appropriate to take a rectal temperature in a child diagnosed with leukemia?

Taking a rectal temperature in a child diagnosed with leukemia is not appropriate due to the risk of introducing bacteria into the bloodstream or the rectal mucosa, which can lead to infections. Children with leukemia often have compromised immune systems, making them more susceptible to infections from even minor procedures. Additionally, the rectal area can be more susceptible to bleeding, especially in patients with bone marrow suppression or thrombocytopenia, which is common in leukemia.

For these reasons, alternative methods of temperature measurement, such as oral or axillary, are generally preferred in this population to ensure the safety and well-being of the patient.
