Explanation

70°F (21°C), which falls within the standard therapeutic range for cool water applications (65°F - 80°F).
This temperature is effective for reducing fever by promoting heat loss through conduction (transfer of heat to the cooler water) and evaporation (cooling as water dries on the skin).
It is cool enough to be therapeutic without being so cold that it causes a strong shivering response, which would be counterproductive.

Option A: 98°F is close to normal body temperature and is considered a 'warm' application. It would not be effective in reducing a fever as there is no significant temperature gradient for heat exchange.
Option B: 105°F is a 'hot' temperature. Applying hot water to a person with a fever is dangerous as it would increase their body temperature. Hot soaks are used to increase circulation and relax muscles, not to cool the body.
Option D: 0°F is significantly below the freezing point of water (32°F). Applying water or ice at this temperature directly to the skin would cause severe tissue damage, frostbite, and intense shivering.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Fever management and therapeutic use of hydrotherapy as background academic context rather than a clinical decision trigger.
The primary goal of sponging is to lower a high fever (pyrexia), but it must be done safely. The nurse's priority is to reduce the temperature without causing adverse effects.
A key nursing consideration is to monitor the patient for shivering. Shivering is the body's attempt to generate heat and will counteract the cooling effect of the sponging, potentially raising the core temperature. If shivering occurs, the procedure should be stopped.
What if the patient is a young child? For pediatric patients, tepid sponging (80°F - 93°F) is almost always preferred over cold sponging. This is because children have a larger surface area to body mass ratio and are more susceptible to rapid temperature changes and the adverse effects of cold, including shivering and discomfort.

How to Approach the Question

First, identify the core concept of the question, which is the appropriate temperature for 'cold sponging'.
This is a factual recall question. Access your knowledge of hydrotherapy and fever management principles.
Recall the different categories of water temperature used in healthcare: cold, tepid, warm, and hot.
Evaluate the given options against these categories. Eliminate options that are clearly incorrect, such as those that are too hot (105°F) or dangerously cold (0°F).
Consider the purpose of cold sponging – to reduce fever. A temperature close to body temperature (98°F) would be ineffective.
Select the option (70°F) that falls within the accepted 'cool' or 'cold' range for therapeutic sponging.
