Martha, a 55-year-old with a past medical history of hypertension, asks you about decreasing her risk for sun damage during her frequent beach trips. Which advice is most accurate?

Increasing sun exposure by 10 minutes each day will minimize risk.

Water-resistant sunscreens are all you need while swimming.

Use a sunscreen with SPF of at least 10

Avoid direct sun exposure between 10 AM and 2 PM.

Answer and Explanation

The Correct Answer is D

A.   Increasing sun exposure would actually increase the risk of sun damage and skin cancer rather than minimizing it.
B.   While water-resistant sunscreens are important for protection during swimming, they are not the only measure needed to reduce sun damage, especially during extended sun exposure periods.
C.   A sunscreen with SPF of at least 10 may not provide sufficient protection, especially for someone spending extended periods of time in direct sunlight. Higher SPF is generally recommended.
D.   Avoiding direct sun exposure between 10 AM and 2 PM is crucial because during these hours, the sun's rays are the strongest, increasing the risk of sunburn and skin

damage. Opting for shade or protective clothing during these hours can significantly reduce the risk of sun damage.

Correct Answer is C

Explanation

A. Immunofixation electrophoresis is not primarily used to assess kidney function.

B. Immunofixation electrophoresis is not used to assess lung function.

C. Immunofixation electrophoresis is a laboratory technique used to identify and characterize abnormal proteins in the blood, which is essential in diagnosing conditions like Waldenstrom's macroglobulinemia.
D. Immunofixation electrophoresis is not used to quantify white blood cells (WBCs).

A. Diffusion of gases will be enhanced B. Pulmonary blood supply is compromised C. Ventilation is likely efficient D. Work of breathing will be increased

Correct Answer is D

Explanation

A. Decreased lung compliance doesn't directly enhance gas diffusion; it may impair it due to decreased lung expansion.

B. Decreased lung compliance doesn't necessarily indicate compromised pulmonary blood supply; it's more related to the lung's ability to expand and contract.
C. Decreased lung compliance suggests that ventilation may be impaired because the lungs are less able to expand and contract effectively.
D. Decreased lung compliance means the lungs are stiffer, requiring more effort to breathe, thus increasing the work of breathing.
