What is the medical term for no fever?

The medical term for no fever is afebrile. It means a person's body temperature is within the normal range, typically below 100.4°F (38°C). In CNA charting and verbal reports, you'll use "afebrile" to document that a resident has no fever.

Afebrile vs. Febrile

Febrile means the person has a fever. Afebrile means they do not. For example, a nurse might say, "Mr. Lee is afebrile today," meaning his temperature is normal. This is important because fever is often the first sign of infection, and CNAs are frequently the first to notice it.

How CNAs Use "Afebrile"

When you take a temperature, you'll report the exact reading and whether the resident is afebrile or febrile. Common normal ranges are:

• Oral: 97.6°F to 99.6°F (36.5°C to 37.5°C)
• Axillary: 96.6°F to 98.6°F (35.9°C to 37°C)
• Tympanic: 98.6°F (37°C) or slightly higher

If a temperature is at or above 100.4°F (38°C), the resident is considered febrile. Always report a fever to the nurse immediately, along with any other symptoms like chills, flushing, or confusion.

Why It Matters for the CNA Exam

Questions about vital signs and infection control are common on the written exam. Understanding terms like afebrile helps you answer correctly. For example, a question might ask, "Which finding should the nurse aide report?" and list "afebrile" as a normal finding versus "febrile" as abnormal. Practicing with free CNA practice test with answers can help you get comfortable with this vocabulary.

Documenting Accurately

When charting, write the actual temperature and use the term afebrile if appropriate. Avoid vague notes like "no fever", use the correct medical term to ensure clear communication. For more guidance on documentation, see our subjective observation in CNA practice guide.

Remember, fever is a sign of infection. According to the CDC infection control guidelines, early detection and reporting are key to preventing the spread of illness in healthcare settings.
