Question

A nurse is conducting a health promotion class for clients on sun protection. Which of the following client responses indicates effective teaching?

A. "Sunscreen does not need to be applied on a cloudy day."
B. "If I sunburn in 10 minutes, SPF15 will give me 2.5 hours of sun exposure."
C. "A sun screen over a sun blocker is the best choice for my toddler."
D. "I can expose my 3 month old to the sun if I apply sunscreen."

Answer 1

The correct client response that indicates effective teaching is option B: "If I sunburn in 10 minutes, SPF15 will give me 2.5 hours of sun exposure."

Step-by-step explanation:

The correct client response that indicates effective teaching is option B: "If I sunburn in 10 minutes, SPF15 will give me 2.5 hours of sun exposure."

This response demonstrates an understanding of the concept of Sun Protection Factor (SPF). SPF measures a product's protection from UVB rays, which are the wavelengths that cause sunburn. Higher SPF values provide a longer duration of protection. In this case, the individual understands that if they can tolerate 10 minutes of sun exposure before getting sunburned, SPF15 will allow them to stay in the sun for 2.5 hours without getting burned.

Answer 2

Client response B suggests understanding of sun protection, as it demonstrates knowledge of how SPF15 correlates to sun exposure time. SPF protects against UVB rays, with SPF30 filtering 97% of these rays. Reapplication every two hours is essential, infants under 6 months should not be exposed to the sun, and protection against both UVA & UVB rays is important.

Step-by-step explanation:

The correct client response that indicates effective teaching for sun protection is: "SPF15 will give me 2.5 hours of sun exposure if I sunburn in 10 minutes." When using sunscreen, it is important to choose a product with a sufficient sun protection factor (SPF) and to understand its effectiveness.

The SPF is a measure of a sunscreen's protection against UVB rays and does not quantify protection from UVA radiation. An SPF of 30 is recommended, filtering out approximately 97% of UVB rays. While increasing SPF past 30 offers minimal additional protection, it is still important to choose a broad-spectrum sunscreen that protects against both UVA and UVB rays.

Additionally, sunscreens and sunblocks should be reapplied every two hours, especially after sweating or swimming, as no products are completely waterproof, and some are only water-resistant. For infants under 6 months, it is generally not recommended to expose them to the sun or use sunscreen on their sensitive skin. Instead, protective clothing and shade are preferred.
