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.

Answer and Explanation

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 C

Explanation

Choice C rationale
In the context of suspected acute pancreatitis, an increase in serum amylase is one of the key laboratory findings. Pancreatitis is associated with inflammation of the pancreas, which can result in the release of digestive enzymes such as amylase and lipase into the bloodstream.
Therefore, elevated levels of these enzymes are often used as markers for acute pancreatitis.
Choice A rationale
Decreased serum lipase is not typically associated with acute pancreatitis. In fact, an increase in serum lipase is more commonly seen in acute pancreatitis. Lipase is a digestive enzyme produced by the pancreas, and its levels in the blood can rise when the pancreas is inflamed.
Choice B rationale
Increased serum calcium is not typically associated with acute pancreatitis. While hypercalcemia, or high calcium levels, can be a cause of pancreatitis, it is not a typical finding in the blood tests of patients with acute pancreatitis.
Choice D rationale
Decreased white blood cell (WBC) count is not typically associated with acute pancreatitis. In fact, an increase in WBC count can sometimes be seen in acute pancreatitis due to the body’s inflammatory response to the condition. Hypothyroidism Explore

A. Free T4. B. Serum T3. C. Thyroid stimulating hormone (TSH). D. Serum calcium.

Correct Answer is C

Explanation

Choice A rationale
Free T4 levels are typically low in primary hypothyroidism, not elevated.

Choice B rationale
Serum T3 levels are also typically low in primary hypothyroidism.
Choice C rationale
In primary hypothyroidism, the thyroid gland is not producing enough thyroid hormone, leading to an elevated TSH level as the pituitary gland tries to stimulate more hormone production.
Choice D rationale
Serum calcium levels are not directly affected by primary hypothyroidism.
