Which fever pattern returns to normal at least once every 24 hours?

• A. Afebril
• B. Pyrexia
• C. Intermittent fever
• D. Relapsing fever

Answer: (C)

The concept tested is how fever fluctuates over a 24-hour period. Intermittent fever means the temperature spikes and then returns to normal at least once within each 24-hour cycle. In other words, there are fever episodes followed by a normal temperature, all within the same day. This distinguishes it from persistent or remittent fever, where the temperature stays elevated or never returns to normal within a day. Afebrile simply means no fever, and pyrexia means fever. Relapsing fever involves separate fever episodes separated by longer afebrile intervals (days to weeks), not a single daily return to normal. So the pattern where fever returns to normal at least once every 24 hours is intermittent fever.
