Final answer:
A 38-year-old patient with an axillary temperature of 37.9 degrees Celsius is considered febrile, as it is slightly above the normal body temperature range for adults.
Explanation:
The question addresses whether a 38-year-old patient's axillary temperature of 37.9 degrees Celsius is considered febrile, normal, inaccurate and should be retaken, or hypothermic. Normal body temperature for adults typically ranges from 36.5-37.5 degrees Celsius (97.7-99.5 degrees Fahrenheit), and a temperature above this range, specifically over 37.5 or 38.3 degrees Celsius (99.5 or 100.9 degrees Fahrenheit), is considered indicative of fever or hyperthermia. Therefore, an axillary temperature of 37.9 degrees Celsius in a 38-year-old adult can be considered febrile because it is marginally above the normal range. However, it is important to consider individual variation and clinical symptoms before making a definitive diagnosis.
