Which is the most accurate statement about fever thresholds mentioned in the material?

• A. 38 C is the threshold.
• B. 37 C is the threshold.
• C. 39 C is the threshold.
• D. 40 C is the threshold.

Answer: (A)

Fever is defined by a rising body temperature beyond a standard threshold. In the material, 38 C is the threshold used to label fever. This aligns with common clinical practice, since 38 C (about 100.4 F) is a practical cut-off that distinguishes normal variation from an febrile state when measurements are taken orally or tympanically. Keep in mind that the exact number can vary a bit with the measurement site: rectal temperatures tend to read about 0.5 C higher than oral, while axillary readings are typically about 0.5 C lower. With that in mind, 38 C serves as a consistent definition for fever in most scenarios. Lowering the threshold to 37 C would flag a lot of normal temperatures as fever, while raising it to 39 or 40 C would miss many true fevers, including milder but clinically significant ones.
