What must a nurse provide to a patient with systemic lupus erythematosus planning to spend a day at the beach?

For a patient with systemic lupus erythematosus (SLE), protecting the skin from ultraviolet (UV) light is crucial. Individuals with SLE may experience photosensitivity, where exposure to sunlight can lead to exacerbation of their condition. Therefore, using a waterproof sunscreen with a SPF of at least 15 is essential as it not only provides a protective barrier against UV rays but also ensures that the protection lasts despite water exposure, which is likely when spending a day at the beach.

Waterproof sunscreens are formulated to maintain their effectiveness even when exposed to sweat or water, which is common during beach activities. This is particularly important because frequent reapplication of regular sunscreen may be less feasible when engaging in fun activities or swimming.

Additionally, the use of sunscreen should not be limited to just the peak sun hours (high noon) or dismissed altogether, as UV rays can be harmful at any time during the day. Therefore, comprehensive sun protection is necessary for all hours spent outdoors, especially for individuals with a heightened risk due to their medical condition.
