When a person has a normal body temperature it is called.

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2024

Explanation

The term 'Afebrile' is the correct medical term used to describe a person with a normal body temperature.
The prefix 'a-' means 'without', so 'afebrile' literally translates to 'without fever'.
A normal body temperature range is generally considered to be between 36.5°C and 37.5°C (97.7°F and 99.5°F).
This state indicates that the body's thermoregulatory mechanisms are functioning correctly to maintain homeostasis.

Option B: Febrile describes a person who has a fever, meaning their body temperature is elevated above the normal range.
Option C: Pyrexia is the medical term for fever. It is synonymous with febrile and indicates an elevated body temperature.
Option D: Hypothermia refers to a dangerously low body temperature, typically below 35°C (95°F), which is the opposite of a normal or elevated temperature.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Terminology of body temperature regulation as background academic context rather than a clinical decision trigger.
Accurate temperature assessment and the use of correct terminology (e.g., afebrile, febrile) are fundamental nursing skills essential for monitoring patient status, evaluating treatment effectiveness, and communicating clearly with the healthcare team.
Documenting a patient as 'afebrile' is a key indicator of clinical stability or recovery from an infectious process.
What if? If a patient with a bacterial infection becomes afebrile after receiving an antibiotic, it suggests the treatment is effective. However, if they become afebrile only after receiving an antipyretic (like paracetamol), the underlying infection may still be active and simply masked, requiring continued vigilance and monitoring.

How to Approach the Question

This is a factual recall question that tests your knowledge of basic medical terminology.
First, identify the key phrase in the question stem: 'normal body temperature'.
Next, analyze the options provided. Consider the prefixes and root words. The prefix 'a-' in 'afebrile' often means 'without' or 'not'.
Evaluate each term's definition. 'Febrile' and 'Pyrexia' both refer to fever (high temperature). 'Hypothermia' refers to low temperature ('hypo-' means low).
Conclude that 'Afebrile' (without fever) is the only term that correctly describes a normal body temperature.
