The temperature of eye irrigating solution should be at what degrees (in Fahrenheit)?

Appeared in: DSSSB - 28 August 2019 (Shift-1)

Explanation

The correct temperature for eye irrigation solution is 98-100°F.
This range is equivalent to normal body temperature (approximately 98.6°F or 37°C), which is essential for patient comfort and safety.
Using a solution at body temperature prevents thermal shock, pain, or injury to the highly sensitive corneal tissues.
This temperature minimizes reflex tearing and blinking, allowing the irrigation to be performed effectively.

Option B: This temperature range is above normal body temperature and would feel uncomfortably hot to the eye, potentially causing pain and vasodilation.
Option C: This range is significantly below body temperature. A cold solution would cause discomfort, excessive tearing, and blinking, making the procedure difficult and unpleasant for the patient.
Option D: This temperature is dangerously high for direct contact with the cornea and carries a significant risk of causing a thermal burn and permanent tissue damage.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Safe temperature for eye irrigation solution as background academic context rather than a clinical decision trigger.
Ensuring the correct temperature for irrigating solutions is a critical patient safety measure to prevent iatrogenic injury, such as corneal burns or abrasions.
The principle of using body-temperature solutions is a standard of care that also applies to other procedures like ear irrigations and bladder instillations to prevent discomfort and tissue damage.
What if? If a proper thermometer is unavailable in an emergency, the nurse can test the solution by pouring a small amount over their inner wrist. The fluid should feel neutral—neither warm nor cool. This is a less precise method and should be used with caution as a last resort.

How to Approach the Question

First, identify the core of the question: the safe temperature for a solution being introduced to a sensitive body part (the eye).
Recall the physiological principle that body cavities and mucous membranes are sensitive to temperature extremes.
Relate the required temperature to the normal human body temperature, which is approximately 98.6°F (37°C).
Evaluate the given options to determine which one best aligns with normal body temperature.
The range 98-100°F is the only option that safely and comfortably brackets the body's natural temperature, making it the logical and correct choice.
