Final answer:
Pyrexia is the term for elevated temperature greater than 38°C postpartum, suggesting potential postpartum complications or infections.
Step-by-step explanation:
The term that describes a temperature greater than 38°C on 2 out of 10 days postpartum (excluding the first 24 hours) when taken orally more than 4 times a day is known as pyrexia.
In the context of this scenario, pyrexia is an indication that the body's temperature is elevated above the normal range, which may suggest an infection or other postpartum complications. Normal body temperature is typically between 36.5°C and 37.5°C (97.7°F to 99.5°F), and the upward adjustment of the body temperature set point can be caused by various factors, including infections or inflammatory processes.
