❓ Frequently Asked Questions
Q: What is the normal body temperature range and when is a fever considered significant?
A: Normal body temperature typically ranges from 97°F to 99°F (36.1°C to 37.2°C). A fever is generally defined as a temperature of 100.4°F (38°C) or higher.
Q: What are common causes of fever?
A: Fever can be caused by a wide range of factors including infections (viral, bacterial, fungal), inflammation, autoimmune diseases, and certain medications.
Q: How does the body regulate temperature?
A: The hypothalamus in the brain acts as the body’s thermostat, regulating temperature through mechanisms like sweating, shivering, and changes in blood vessel diameter.
Q: What are some important aspects of a physical exam when a patient has a fever?
A: Key aspects include assessing vital signs (temperature, heart rate, respiratory rate, blood pressure), examining the skin for rashes, checking for signs of infection (e.g., throat, ears, lungs), and evaluating neurological status.
Q: When should I seek medical attention for a fever?
A: Seek medical attention if you have a high fever (over 103°F or 39.4°C), fever accompanied by severe symptoms (e.g., stiff neck, confusion, difficulty breathing), or if the fever persists for more than a few days.
Q: How does fever help the body fight infection?
A: Elevated body temperature can inhibit the growth of certain pathogens and enhance the immune system’s ability to fight infection by increasing the activity of white blood cells.
