Nurses should advise patients to take several precautions to protect themselves from harmful UV rays: - Use Sunscreen: Encourage the use of a broad-spectrum sunscreen with an SPF of at least 30. Apply generously and reapply every two hours, or after swimming or sweating. - Wear Protective Clothing: Long-sleeved shirts, wide-brimmed hats, and sunglasses can provide a physical barrier against UV rays. - Seek Shade: Advise patients to stay in the shade, especially during peak sun intensity hours (10 AM to 4 PM). - Avoid Tanning Beds: Emphasize that tanning beds also emit harmful UV radiation and should be avoided.
