What effect does chronic exposure to ultraviolet (UV) rays have on the skin that increases the risk for skin cancer?
Decreases the water content of the skin
Causes an error in the skin’s genetic code
Increases in blood flow to the skin
Causes degeneration of elastic fibers in skin tissue.
The Correct Answer is B
Choice A rationale
While chronic exposure to UV rays can cause skin dryness, it does not decrease the water content of the skin20. Skin dryness is more of a symptom rather than a risk factor for skin cancer20.
Choice B rationale
Chronic exposure to UV rays can cause an error in the skin’s genetic code20. This can lead to the development of skin cancer, as the damaged DNA can lead to uncontrolled cell growth20.
Choice C rationale
Increased blood flow to the skin is not a direct result of chronic exposure to UV rays20. While UV rays can cause skin redness and inflammation, these are not directly linked to an increased risk of skin cancer20.
Choice D rationale
Chronic exposure to UV rays does not cause degeneration of elastic fibers in skin tissue20. While UV rays can cause skin aging and wrinkles, these are not direct risk factors for skin cancer20. Diabetic retinopathyDiabetic retinopathy Explore

Correct Answer is B
Explanation
Choice A rationale
Maintaining systolic BP between 136 and 140 mm Hg is not recommended for clients who have hypertension and have experienced a TIA789. Studies have shown that maintaining a lower systolic BP can help reduce the risk of recurrent stroke.
Choice B rationale
The client should aim to maintain systolic BP between 120 and 129 mm Hg. This range is associated with a reduced risk of recurrent stroke. Lifestyle modifications and antihypertensive therapy can help achieve this target.
Choice C rationale
Maintaining systolic BP between 141 and 145 mm Hg is not recommended for clients who have hypertension and have experienced a TIA789. This range is higher than the recommended target and may increase the risk of recurrent stroke.
Choice D rationale
Maintaining systolic BP between 130 and 135 mm Hg is not the recommended target for clients who have hypertension and have experienced a TIA789. The recommended target is lower to help reduce the risk of recurrent stroke.
