What should a nurse do to prepare for a skin examination using a Wood light?

To effectively prepare for a skin examination using a Wood light, it is essential to darken the room. Wood light examinations are conducted in low-light conditions to enhance the visibility of various skin conditions that fluoresce under ultraviolet light. By reducing ambient light, the nurse ensures that the visual contrast is maximized, allowing for a more accurate assessment of the skin's characteristics and any abnormal findings.

The fluorescence produced by certain skin conditions can be subtle and less noticeable if there is excessive ambient light. Therefore, creating a darker environment is crucial for the nurse to interpret the results of the Wood light examination accurately. This practice allows for a better differentiation between normal skin and conditions that may require further evaluation or treatment.
