Explanation

The term 'tepid' refers to a lukewarm temperature. The range of 27–37° C is slightly below normal body temperature (approximately 37°C).
This temperature gradient allows for effective heat loss from the body to the water through conduction and evaporation.
Using water in this range is crucial because it is cool enough to reduce fever but warm enough to prevent the body from initiating a shivering response.
Shivering is a physiological mechanism to generate heat, which would be counterproductive to the goal of lowering body temperature.

Option A: The range of 16–18° C is classified as cold sponging. This temperature is too low and is likely to cause significant shivering and vasoconstriction, which traps heat and can paradoxically increase the core body temperature.
Option B: The range of 18–25° C is considered cool sponging. While cooler than tepid, it still carries a substantial risk of inducing shivering and causing patient discomfort, making it less ideal than tepid sponging.
Option D: The range of 40–45° C is for a hot or warm application. Applying water at this temperature would add heat to the body, thereby increasing the patient's fever, not reducing it.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Temperature ranges for therapeutic baths and sponging for fever management as background academic context rather than a clinical decision trigger.
Using the correct water temperature for tepid sponging is a critical nursing skill that directly impacts patient safety and comfort. Incorrect temperatures can lead to adverse physiological responses.
A core principle of fever management is to cool the patient gradually. Rapid cooling with cold water can cause peripheral vasoconstriction, which impairs heat loss and can lead to a rebound increase in core temperature.
What if the patient has a very high fever (e.g., 40.5°C)? The principle remains the same. Tepid sponging is still the preferred method. It should be used as an adjunct to, not a replacement for, prescribed antipyretic medications. The goal is a controlled, gradual decrease in temperature.

How to Approach the Question

First, identify the key term in the question: 'tepid sponging'.
Recall the definition of 'tepid', which means lukewarm or moderately warm.
Consider the physiological goal: to reduce fever without causing shivering. Shivering generates heat, so the water cannot be too cold.
Evaluate the options in relation to normal body temperature (~37°C). The water must be cooler than the body to allow heat transfer.
Eliminate the 'cold' (16-18°C) and 'cool' (18-25°C) options as they are likely to cause shivering.
Eliminate the 'hot' (40-45°C) option as it would raise, not lower, body temperature.
