What letter should be written after temperature numbers to indicate that a rectal method was used?

When documenting a rectal temperature, it is standard practice to use the letter "R" after the temperature number. This notation specifies that the method of measurement was rectal, which is significant because different methods can yield varying results. For instance, rectal temperatures are typically higher than oral temperatures, so clear documentation is crucial for accurate patient assessments and treatment decisions. By using "R," healthcare providers can ensure they understand the context of the temperature reading, which aids in monitoring a patient's clinical condition effectively.
